NOTICE: will also be indicated by a bold key word embedded in the text followed by an italicized safety message. Failure to comply will result in death or serious injury. The operating company is responsible for any injuries or equipment damage resulting from failure to heed the warnings in this manual. Electrical Shock Hazard Do not connect or disconnect wiring while the power is on. Before servicing, disconnect all power to the equipment. The internal capacitor remains charged even after the power supply is turned off.
After shutting off the power, wait for at least the amount of time specified on the drive before touching any components. Sudden Movement Hazard System may start unexpectedly upon application of power, resulting in death or serious injury. Clear all personnel from the drive, motor and machine area before applying power.
Secure covers, couplings, shaft keys and machine loads before applying power to the drive. Unpredictable equipment operation may result in death or serious injury. Electrical Shock Hazard Do not attempt to modify or alter the drive in any way not explained in this manual. Failure to comply could result in death or serious injury. Yaskawa is not responsible for any modification of the product made by the user. This product must not be modified.
Do not allow unqualified personnel to use equipment. Maintenance, inspection, and replacement of parts must be performed only by authorized personnel familiar with installation, adjustment and maintenance of AC drives.
Do not remove covers or touch circuit boards while the power is on. Fire Hazard Do not use an improper voltage source. Failure to comply could result in death or serious injury by fire.
Verify that the rated voltage of the drive matches the voltage of the incoming power supply before applying power. Crush Hazard Do not use this drive in lifting applications without installing external safety circuitry to prevent accidental dropping of the load. The drive does not possess built-in load drop protection for lifting applications. Failure to comply could result in death or serious injury from falling loads. Crush Hazard Do not carry the drive by the front cover.
Failure to comply may result in minor or moderate injury from the main body of the drive falling. Failure to comply may result in ESD damage to the drive circuitry.
Do not perform a withstand voltage test on any part of the drive. Failure to comply could result in damage to the sensitive devices within the drive. Do not operate damaged equipment. Failure to comply could result in further damage to the equipment. Do not connect or operate any equipment with visible damage or missing parts.
Install adequate branch circuit short circuit protection per applicable codes. Failure to comply could result in damage to the drive. Do not expose the drive to halogen group disinfectants. Failure to comply may cause damage to the electrical components in the drive. Do not pack the drive in wooden materials that have been fumigated or sterilized. Do not sterilize the entire package after the product is packed. For specialized motors, make sure that the motor rated current is less than rated output current for the drive.
When running more than one motor in parallel from a single drive, the capacity of the drive should be larger than 1. Starting Torque. The overload rating for the drive determines the starting and accelerating characteristics of the motor. Expect lower torque than when running from line power. To get more starting torque, use a larger drive or increase both the motor and drive capacity. Emergency Stop. When the drive faults out, the output is shut off. This, however, does not stop the motor immediately.
Some type of mechanical brake may be needed if it is necessary to halt the motor faster than the Fast Stop function is able to. Connect only Acompatible devices. Heat stress generated from repetitive high current can shorten the life span of the IGBTs.
Yaskawa recommends lowering the carrier frequency, particularly when audible noise is not a concern. The user can also choose to reduce the load, increase the acceleration and deceleration times, or switch to a larger drive. Be sure to check the peak current levels when starting and stopping repeatedly during the initial test run, and make adjustments accordingly.
The drive should be one frame size larger than the motor. Installation Enclosure Panels. Keep the drive in a clean environment by either selecting an area free of airborne dust, lint, and oil mist, or install the drive in an enclosure panel. Be sure to leave the required space between drives to provide for cooling, and that proper measures are taken so that the ambient temperature remains within allowable limits.
Keep flammable materials away from the drive. If the drive must be used in an area where it is subjected to oil mist and excessive vibration, protective designs are available. Contact Yaskawa or your Yaskawa agent for details. Installation Direction. The drive should be installed upright as specified in the manual. For more information on installation, Refer to Mechanical Installation on page Settings Upper Limits. The drive is capable of running the motor up to Hz.
Due to the danger of accidentally of operating at high speed, be sure to set the upper limit for the frequency. The default setting for the maximum output frequency is 50 Hz. DC Injection Braking.
Acceleration and deceleration times are affected by how much torque the motor generates, the load torque, and the inertia moment. For faster acceleration and deceleration, install one of the braking options available or increase the capacity of the drive. Doing so will destroy the drive. Be sure to perform a final check of all sequence wiring and other connections before turning the power on.
Type B according to IEC Magnetic Contactor Installation. Use a magnetic contactor MC to ensure that power to the drive can be completely shut off when necessary. The MC should be wired so that it opens when a fault output terminal is triggered. Avoid switching a magnetic contactor on the power supply side more frequently than once every 30 minutes.
Frequent switching can cause damage to the drive. Inspection and Maintenance. Capacitors in the drive take time to discharge even after the power has been shut off. The heatsink can become quite hot during operation, and proper precautions should be taken to prevent burns. When replacing the cooling fan, shut off the power and wait at least 15 minutes to be sure that the heatsink has cooled down. Even when the power has been shut off for a drive running a PM motor, voltage continues to be generated at the motor terminals while the motor coasts to stop.
Take the precautions described below to prevent shock and injury: In Applications where the machine can still rotate even though the drive has fully stopped a load switch for disconnecting motor and drive should be installed to the output side of the drive. Do not allow an external force to rotate the motor beyond the maximum allowable speed, also when the drive has been shut off. Wait for at least the time specified on the warning label after opening the load switch on the output side before inspecting the drive or performing any maintenance.
Do not open and close the load switch while the motor is running, as this can damage the drive. If the motor is coasting, make sure the power to the drive is turned on and the drive output has completely stopped before closing the load switch. Use only the tools recommended by the terminal manufacturer for crimping. Transporting the Drive. Never steam clean the drive. During transport, keep the drive from coming into contact with salts, fluorine, bromine, phthalate ester, and other such harmful chemicals.
The cooling fan of a standard motor is usually designed to sufficiently cool the motor at the rated speed. As the selfcooling capability of such a motor reduces with the speed, applying full torque at low speed will possibly damage the motor. To prevent motor damage from overheat, reduce the load torque as the motor slows. Consider voltage tolerance levels and insulation in applications with an input voltage of over V or particularly long wiring distances. Contact Yaskawa or your Yaskawa agent for consultation.
High Speed Operation. Problems may occur with the motor bearings and dynamic balance of the machine when operating a motor beyond its rated speed.
Contact the motor or machine manufacturer. Torque Characteristics. Torque characteristics differ compared to operating the motor directly from line power. The user should have a full understanding of the load torque characteristics for the application. Vibration and Shock. Selecting high carrier PWM can help reduce motor oscillation. Take particular caution when using a variable speed drive for an application that is conventionally run from line power at a constant speed.
If resonance occurs shock-absorbing rubber should be installed around the base of the motor and the Jump frequency selection should be enabled to prevent continuous operation in the resonant frequency range. Audible Noise. Noise created during run varies by the carrier frequency setting. When using a high carrier frequency, audible noise from the motor is comparable to the motor noise generated when running from line power.
Using a Synchronous Motor Contact Yaskawa or your Yaskawa agent if you plan to use any other synchronous motor not endorsed by Yaskawa. A single drive is not capable of running multiple synchronous motors at the same time.
Use a standard induction motor for such setups. At start, a synchronous motor may rotate slightly in the opposite direction of the Run command depending on parameter settings and rotor position.
The amount of starting torque that can be generated differs by each control mode and by the type of motor being used.
Set up the motor with the drive after verifying the starting torque, allowable load characteristics, impact load tolerance, and speed control range. Contact Yaskawa or your Yaskawa agent if you plan to use a motor that does not fall within these specifications. In Open Loop Vector Control for PM motors, the allowable load inertia moment is approximately 50 times higher than the motor inertia moment or less. Contact Yaskawa or your Yaskawa agent concerning applications with a larger inertia moment.
Failure to set the proper timing can result in speed loss. Not for use with conveyor, transport, or hoist type applications. Short Circuit Braking requires a special braking resistor. Speed Search can be used to restart a coasting motor rotating slower than Hz. If the motor cable is relatively long, however, the motor should instead be stopped using Short Circuit Braking, which forces the motor to stop by creating a short-circuit in the motor windings.
Because the rated current will differ from a standard motor, be sure to check the maximum current when selecting a drive. Always stop the motor before switching between the number of motor poles. If a regen overvoltage fault occurs or if overcurrent protection is triggered, the motor will coast to stop. Because motor rated current is greater than a standard motor, select the drive capacity accordingly. Be sure to use a large enough motor cable to avoid decreasing the maximum torque level on account of voltage drop caused by a long motor cable.
Explosion-Proof Motor. Both the motor and drive need to be tested together to be certified as explosion-proof. The drive is not designed for explosion proof areas. Furthermore, if an encoder is attached to an explosion-proof motor make sure the encoder is explosion-proof too. Use an insulating signal converter for connecting the encoder signal lines to the drives speed feedback option card. Geared Motor. To avoid gear damage when operating at low speeds or very high speeds, make sure that both the gear and lubricant are rated for the desired speed range.
Consult with the manufacturer for applications that require operation outside the rated speed range of the motor or gear box. Single-Phase Motor. Variable speed drives are not designed for operation with single phase motors. Using capacitors to start the motor causes excessive current to flow and can damage drive components.
A split-phase start or a repulsion start can end up burning out the starter coils because the internal centrifugal switch is not activated. A is for use with three-phase motors only. Motor with Brake. Caution should be taken when using a drive to operate a motor with a built-in holding brake. If the brake is connected to the output side of the drive, it may not release at start due to low voltage levels. A separate power supply should be installed for the motor brake. Motors with a built-in brake tend to generate a fair amount of noise when running at low speeds.
Notes on Power Transmission Parts belts, chains, gear boxes, Installing a drive in a machine that was directly connected to the power supply allows to adjust the machine speed. Continuous operation above or below the rated speed can wear on lubrication material in gear boxes and other power transmission parts. In order to avoid machine damage make sure lubrication is sufficient within the whole speed range. Note that operation above the rated speed can increase the noise generated by the machine.
Drive Label Warnings Always heed the warning information listed in Figure i. Figure i. Wait 5 minutes for capacitor YEG discharge after disconnecting power supply.

Do not carry the drive by the front cover or the terminal cover.
Failure to comply may cause the main body of the drive to fall, resulting in minor or moderate injury. A motor connected to a PWM drive may operate at a higher temperature than a utility-fed motor and the operating speed range may reduce motor cooling capacity. A Model Selection Table 1. Note: The models and capacities in shown here are based on standard settings and operation conditions.
Derating is required for higher carrier frequencies and higher ambient temperatures. Motor Power kW 0. Note: Current derating is required when setting the carrier frequency higher. Refer to Carrier Frequency Derating on page for details. Control Mode Selection Table 1. Table 1. May fluctuate with characteristics and motor temperature. Speed deviation when operating at constant speed. Performance may differ by capacity. Automatically adjusts parameter settings that concern electrical characteristics of the motor.
Sets the maximum torque for the motor to protect the load and connected machinery. Allows direct control of motor torque for tension control and other such applications. Bi-directional speed detection of a coasting motor to restart it without stopping. Saves energy by always operating the motor at its maximum efficiency. Increases motor loss to allow for faster deceleration than normal without the use of a braking resistor. The effectiveness may vary based on motor characteristics. Improves speed accuracy when the load changes by compensating effects of the system inertia.
Decelerates the drive to allow it to ride through a momentary power loss and continue operation. Provides fast deceleration without using a braking resistor. Provides automatic Speed Control and Feed Forward function tuning. Prevents overvoltage by increasing speed during regeneration. Never use this function with hoist or crane applications. Greatly increases the speed control range of an IPM motor. Please perform the following tasks after receiving the drive: Inspect the drive for damage.

If you have received the wrong model or the drive does not function properly, contact your supplier. MOTOR : 5. Note: Refer to Drive Models and Enclosure Types on page 31 for differences regarding enclosure protection types and component descriptions.
Two types of enclosures are offered for A drives. IP00 enclosure models are designed for installation in an enclosure panel that serves to protect personnel from injury caused by accidentally touching live parts.
This section gives and overview of the drive components described in this manual. Note: 1. See Using the Digital Operator on page 87 for a description of the operator keypad. The drive may have no cooling fans or only one cooling fan depending on the model. Fire Hazard Provide sufficient cooling when installing the drive inside an enclosed panel or cabinet.
Failure to comply could result in overheating and fire. When multiple drives are placed inside the same enclosure panel, install proper cooling to ensure air entering the enclosure does not exceed 40C.
Crush Hazard Do not carry the drive by the front cover or the terminal cover. Equipment Hazard Prevent foreign matter such as metal shavings or wire clippings from falling into the drive during drive installation and project construction. Place a temporary cover over the top during installation.
Be sure to remove the temporary cover before start-up, as the cover will reduce ventilation and cause the unit to overheat. Observe proper electrostatic discharge ESD procedures when handling the drive. Failure to comply could result in ESD damage to the drive circuitry. Operating the motor in the low-speed range diminishes the cooling effects, increases motor temperature, and may lead to motor damage by overheating.
Reduce the motor torque in the low-speed range whenever using a standard blower cooled motor. Select a motor that is compatible with the required load torque and operating speed range. The speed range for continuous operation differs according to the lubrication method and motor manufacturer. If the motor is to be operated at a speed higher than the rated speed, consult with the manufacturer.
Continuously operating an oil-lubricated motor in the low-speed range may result in burning. When the input voltage is V or higher or the wiring distance is greater than meters, pay special attention to the motor insulation voltage or use a drive-rated motor with reinforced insulation. Failure to comply could lead to motor winding failure. Motor vibration may increase when operating a machine in variable-speed mode, if that machine previously operated at a constant speed.
Install vibration-proof rubber on the motor base or use the frequency jump function to skip a frequency resonating the machine. The motor may require more acceleration torque with drive operation than with a commercial power supply.
The rated input current of submersible motors is higher than the rated input current of standard motors. Select an appropriate drive according to its rated output current. When the distance between the motor and drive is long, use a cable thick enough to connect the motor to the drive to prevent motor torque reduction. The current rating differs for a motor with variable pole pitches differs from a standard motor.
Check the maximum current of the motor before selecting the drive capacity. Only switch motor poles when the motor is stopped. Switching between motor during run will trigger overcurrent protection circuitry or result in overvoltage from regeneration, and the motor will simply coast to stop.
When using an explosion-proof motor, it must be subject to an explosion-proof test in conjunction with the drive. This is also applicable when an existing explosion-proof motor is to be operated with the drive. Since the drive itself is not explosion-proof, always install it in a safe place. Never lift the drive up while the cover is removed. This can damage the terminal board and other components.
This section outlines specifications, procedures, and the environment for proper mechanical installation of the drive. Installation Environment To help prolong the optimum performance life of the drive, install the drive in an environmental matching the specifications below.
Table 2. When using the drive in an enclosure panel, install a cooling fan or air conditioner in the area to ensure that the air temperature inside the enclosure does not exceed the specified levels. Do not allow ice to develop on the drive. Install the drive in an area free from: oil mist and dust metal shavings, oil, water or other foreign materials radioactive materials combustible materials e. NOTICE: Avoid placing drive peripheral devices, transformers, or other electronics near the drive as the noise created can lead to erroneous operation.
If such devices must be used in close proximity to the drive, take proper steps to shield the drive from noise. NOTICE: Prevent foreign matter such as metal shavings and wire clippings from falling into the drive during installation. Place a temporary cover over the top of the drive during installation.
Remove the temporary cover before startup, as the cover will reduce ventilation and cause the drive to overheat. Installation Orientation and Spacing Install the drive upright as illustrated in Figure 2. Figure 2. When installing multiple drives into the same enclosure panel, mount the drives according to Figure 2. When mounting drives with the minimum clearance of 2 mm according to Figure 2. Refer to Temperature Derating on page Leave space between the top and bottom of stacked drives for easy cooling fan replacement if required.
Refer to Top Protective Cover on page 64 to remove and reattach the top protective cover. Digital Operator Remote Usage Remote Operation The digital operator mounted on the drive can be removed and connected to the drive using an extension cable up to 3 m long. This makes it easier to operate the drive when it is installed in a location where it can not be accessed easily. The digital operator can also be permanently mounted in a remote location like a panel door.
An extension cable and an installation support set depending on the installation type will be required. Note: Refer to Drive Options and Peripheral Devices on page for information on extension cables and installation support sets.
There are two ways the digital operator can be mounted to an enclosure: 1. Simplified installation with the digital operator is mounted on the outside of the panel with two screws. Installation Support Set A for mounting with screws through holes in the panel. Encloses the digital operator in the panel. The digital operator is flush with the outside of the panel. Installation Support Set B for use with threaded studs that are fixed to the panel.
Note: Prevent foreign matter such as metal shavings or wire clippings from falling into the drive during installation and project construction. Cut an opening in the enclosure panel for the digital operator as shown in Figure 2. Position the digital operator so the display faces outwards, and mount it to the enclosure panel as shown in Figure 2. An internal flush-mount requires an installation support set that must be purchased separately. Contact your Yaskawa representative to order an installation support set and mounting hardware.
Mount the digital operator to the installation support. Mount the installation support set and digital operator to the enclosure panel. Exterior and Mounting Dimensions Table 2. Electrical Shock Hazard Do not operate equipment with covers removed. The diagrams in this section may show drives without covers or safety shields to show details. Be sure to reinstall covers or shields before operating the drives and run the drives according to the instructions described in this manual.
Always ground the motor-side grounding terminal. Improper equipment grounding could result in death or serious injury by contacting the motor case.
Do not perform work on the drive while wearing loose clothing, jewelry or without eye protection. Remove all metal objects such as watches and rings, secure loose clothing, and wear eye protection before beginning work on the drive. Do not allow unqualified personnel to perform work on the drive. Installation, maintenance, inspection, and servicing must be performed only by authorized personnel familiar with installation, adjustment, and maintenance of AC drives. Do not touch any terminals before the capacitors have fully discharged.
Before wiring terminals, disconnect all power to the equipment. Fire Hazard Tighten all terminal screws to the specified tightening torque. Loose electrical connections could result in death or serious injury by fire due to overheating of electrical connections.
Do not use improper combustible materials. Do not install the drive to a combustible surface. Never place combustible materials on the drive. Do not use an improper voltage source.
When installing dynamic braking options, perform all wiring exactly as specified in the wiring diagrams provided. Failure to do so can result in fire. Improper wiring may damage braking components. Observe proper electrostatic discharge procedures ESD when handling the drive and circuit boards. Never connect or disconnect the motor from the drive while the drive is outputting voltage. Improper equipment sequencing could result in damage to the drive. Do not use unshielded cable for control wiring.
Failure to comply may cause electrical interference resulting in poor system performance. Use shielded, twisted-pair wires and ground the shield to the ground terminal of the drive. Do not allow unqualified personnel to use the product. Failure to comply could result in damage to the drive or braking circuit.
Carefully review instruction manual TOBPC when connecting a dynamic braking option to the drive. Do not modify the drive circuitry. Failure to comply could result in damage to the drive and will void warranty. Check all the wiring to ensure that all connections are correct after installing the drive and connecting any other devices.
Connect the drive and peripheral devices as shown in Figure 3. NOTICE: When the input voltage is V or higher or the wiring distance is greater than meters, pay special attention to the motor insulation voltage or use a drive duty motor.
Failure to comply could lead to motor insulation breakdown. Improper drive grounding can cause control circuit malfunction. Figure 3. Never connect power supply lines to these terminals. Multi-function relay output Speed Agree 1 Vac, max.
Multi-function relay output Zero Speed Vac, max. Multi-function relay output During Run Vac, max. If left enabled, a braking resistor fault rF may result. If left enabled, the drive may not stop within the specified deceleration time. Leave it out for external power supply. Never short terminals SP and SN as doing so will damage the drive. The default setting is for current input. They are not intended for use as a feedback-type of signal. Set parameters H and H accordingly.
Sudden Movement Hazard. Do not close the wiring for the control circuit unless the multifunction input terminal parameters are properly set. Failure to comply could result in death or serious injury from moving equipment. When programmed for 3-Wire control, a momentary closure on terminal S1 may cause the drive to start. When 3-Wire sequence is used, set the drive to 3-Wire sequence before wiring the control terminals and ensure parameter b is set to 0 drive does not accept a run command at power up default.
If the drive is wired for 3-Wire sequence but set up for 2-Wire sequence default and if parameter b is set to 1 drive accepts a Run command at power up , the motor will rotate in reverse direction at power up of the drive and may cause injury. This may cause unexpected operation and potential damage to equipment or injury. Otherwise the fault restart function can not work properly. Refer to diagrams in this section when wiring the drives main circuit.
Connections may vary based on drive capacity. The DC power supply for the main circuit also provides power to the control circuit.
This terminal is at high DC voltage potential. Improper wiring connections could damage the drive. Follow the procedure below to remove the terminal cover for wiring and to reattach the terminal cover after wiring is complete. Loosen the terminal cover screw.
Push in on the hook located on the bottom of the terminal cover, and gently pull forward. This should remove the terminal cover. Reattaching the Terminal Cover Power lines and signal wiring should pass through the opening provided. After all wiring to the drive and other devices is complete, reattach the terminal cover. Connect ground wiring first, followed by the main circuit, and then wire the control circuit.
Power lines and signal wiring exit through the opening provided. Do not completely remove the cover screws, just loosen them. If the cover screws are removed completely, the terminal cover may fall off causing an injury. Reattaching the Terminal Cover Once wiring to the terminal board and other devices is complete, double check all connections and finally reattach the terminal cover.
The digital operator can be detached from the drive for remote operation, or when the front cover has to be opened to install an option card. Leaving the digital operator plugged into the drive when removing the front cover can result in erroneous operation caused by a poor connection. Before reattaching the operator make sure the front cover has been firmly fastened back into place.
Reattaching the Digital Operator Insert the digital operator into the opening in the front cover while aligning it with the notches on the left side of the opening. Next press gently on the right side of the operator until it clicks into place.
After removing the terminal cover and the digital operator, loosen the screw that affixes the front cover model CIMRA2A, 4A, 4A do not use a screw to affix the front cover. Pinch inwards on hooks found on each side of the front cover, then pull forward to remove it from the drive. Remove the terminal cover and the digital operator. Loosen the installation screw on the front cover. Use a straight-edge screwdriver to loosen the hooks on each side of the cover that hold it in place.
First unhook the left side of the front cover, then swing the left side towards you as shown in the figure below until the cover comes off. Reverse the instructions given in Removing the Front Cover on page 61 to reattach the front cover. Pinch inwards on the hooks found on each side of the front cover while guiding it back into the drive.
Make sure it clicks firmly into place. Once the hooks have connected to the drive, press firmly on the cover to make sure it locks into place. Removing this top protective cover voids the NEMA Type 1 conformance but still keeps a protection degree in accordance with IP20 enclosure.
Removing the Top Protective Cover Insert the tip of a straight-edge screwdriver into the small openings located on the front edge of the top protective cover. Gently apply pressure as shown in the figure below to free the cover from the drive. Reattaching the Top Protective Cover Align the small protruding hooks on the sides of the top protective cover with the corresponding mounting holes on the top of the drive. Pinch the hooks inward so that the they connect with the mounting holes and fasten the top protective cover back into place.
This section describes the functions, specifications, and procedures required to safely and properly wire the main circuit in the drive. Soldered wiring connections can loosen over time. Improper wiring practices could result in drive malfunction due to loose terminal connections. Frequently switching the drive on and off shortens the lifetime of the DC bus charge circuit and the DC bus capacitors, and can cause premature drive failures.
For the full performance life, refrain from switching the drive on and off more than once every 30 minutes. Main Circuit Terminal Functions Table 3. Insulation Cap Use insulation caps when wiring the drive with crimp terminals. Take particular care to ensure that wiring does not touch neighboring terminals or the surrounding case. Yaskawa recommends using the insulation barriers provided to ensure proper wiring.
See Figure 3. Wire Gauges and Tightening Torque Select the appropriate wires and crimp terminals from through. Wire gauge recommendations based on drive continuous current ratings ND using 75C Vac vinyl-sheathed wire assuming ambient temperature within 40C and wiring distance less than m.
Do not connect other nonspecific devices to these terminals. Consider the amount of voltage drop when selecting wire gauges. Ensure the wire gauge is suitable for the terminal block. Three-Phase V Class Table 3.
Main Circuit Terminal and Motor Wiring This section outlines the various steps, precautions, and checkpoints for wiring the main circuit terminals and motor terminals.
Failure to comply with proper wiring practices may cause the motor to run in reverse if the phase order is backward. Failure to comply could result in death or serious injury by fire as a result of drive damage from line voltage application to output terminals. Cable Length Between Drive and Motor Voltage drop along the motor cable may cause reduced motor torque when the wiring between the drive and the motor is too long, especially at low frequency output.
This can also be a problem when motors are connected in parallel with a. Drive output current will increase as the leakage current from the cable increases. An increase in leakage current may trigger an overcurrent situation and weaken the accuracy of the current detection. Adjust the drive carrier frequency according to Table 3. If the motor wiring distance exceeds m because of the system configuration, reduce the ground currents. Refer to C Carrier Frequency Selection on page Table 3. Note: When setting carrier frequency in a drive running multiple motors, calculate the cable length as the total distance of wiring to all motors that are connected.
Ground Wiring Follow the precautions to wire the ground for one drive or a series of drives. Electrical Shock Hazard. Always use a ground wire that complies with technical standards on electrical equipment and minimize the length of the ground wire.
Improper equipment grounding may cause dangerous electrical potentials on equipment chassis, which could result in death or serious injury. Be sure to ground the drive ground terminal. Improper equipment grounding could result in death or serious injury by contacting ungrounded electrical equipment.
