WARNING

Electrical Shock Hazard. Do not make changes to the drive body or drive circuitry. Failure to obey can cause

death or serious injury and will void warranty. The manufacturer is not responsible for changes to the product made by the user.

WARNING

Electrical Shock Hazard. Only let authorized persons install, wire, maintain, examine, replace parts, and

repair the drive. Failure to obey can cause death or serious injury.

WARNING

Electrical Shock Hazard. Always ground the motor-side grounding terminal. Contacting the motor case can

cause death or serious injury from incorrect equipment grounding.

WARNING

Electrical Shock Hazard. Do not work on the drive or around the drive while wearing loose clothing or jewelry.

Tighten loose clothing and remove all metal objects such as watches or rings. Failure to obey can cause death or serious injury.

WARNING

2007 standard specifies that users must wire the power supply to automatically turn off when the protective ground wire disconnects. Users can also connect a protective ground wire that has a minimum cross-sectional area of 10 mm or 16 mm

WARNING

Electrical Shock Hazard. The leakage current of the drive will be more than 3.5 mA. The IEC/EN 61800-5-1:

(aluminum wire). Failure to obey these standards can cause death or serious injury.

Sudden Movement Hazard. Remove all persons and objects from the area around the drive, motor, and load

(copper wire)

before starting Auto-Tuning. The drive and motor can start suddenly during Auto-Tuning and cause death or serious injury.

WARNING

Sudden Movement Hazard. Remove all persons and objects from the area around the drive, motor, and machine area and attach covers, couplings, shaft keys, and machine loads before energizing the drive. Failure to obey can cause death or serious injury.

WARNING

Fire Hazard. Do not use the main circuit power supply (Overcurrent Category III) at incorrect voltages. Make sure that the drive rated voltage aligns with the power supply voltage before energizing the drive. Failure to obey can cause death or serious injury.

WARNING

Fire Hazard. Do not put flammable or combustible materials on top of the drive and do not install the drive near flammable or combustible materials. Attach the drive to metal or other noncombustible material. Failure to obey can cause death or serious injury.

WARNING

Fire Hazard. Tighten all terminal screws to the correct tightening torque. Connections that are too loose or too tight can cause incorrect operation and damage to the drive. Incorrect connections can also cause death or serious injury from fire.

WARNING

Fire Hazard. Tighten screws against the bit at an angle in the specified range described in this manual. Tightening screws at an angle outside of the specified range can cause damage the terminal block or start a fire if the connection is loose.

WARNING

Crush Hazard. Use a lifting mechanism made to move large drives when necessary. Failure to obey can cause death or serious injury from falling equipment.

WARNING

Electrical Shock Hazard. Do not cause a short circuit on the drive output circuit. Failure to obey can cause death or serious injury.

WARNING

Electrical Shock Hazard. Always use a type B Residual Current Monitor/Residual Current Device (RCM/RCD) where a residual current operated protective or monitoring device protects against direct or indirect contact as specified by IEC/ EN 60755 The drive can cause a residual current with a DC component in the protective earthing conductor. Failure to obey can cause death or serious injury.

WARNING

Electrical Shock Hazard. Ground the neutral point on the power supply to comply with the EMC Directive before turning on the EMC filter or if there is high resistance grounding. If the EMC filter is switched ON without the neutral point being grounded or if there is high resistance grounding, it can cause death or serious injury.

WARNING

Electrical Shock Hazard. Do not immediately energize the drive or operate peripheral devices after the drive blows a fuse or trips an RCM/RCD. Wait for the time specified on the warning label at a minimum and make sure that all indicators are OFF. Then check the wiring and peripheral device ratings to find the cause of the problem. Contact the manufacturer before energizing the drive or peripheral devices if the cause is not known. Failure to obey can cause death or serious injury and damage to the drive.

WARNING

Fire Hazard. Install sufficient branch circuit short circuit protection as specified by applicable codes and this manual. The drive is suited for circuits that supply not more than 100,000 RMS symmetrical amperes, 240 Vac maximum (200 V Class), 480 Vac maximum (400 V Class). Failure to obey can cause death or serious injury.

CAUTION

Crush Hazard. Do not hold the drive by the front cover or terminal cover. Tighten the screws correctly before moving the drive. Failure to obey can cause minor to moderate injury.

CAUTION

Burn Hazard. Do not touch a hot drive heatsink. De-energize the drive, wait 15 minutes minimum, and make sure that the heatsink is cool to replace the cooling fans. Failure to obey can cause minor to moderate injury.

◆ Troubleshooting

If the drive or motor do not operate correctly, look at the drive keypad for fault and alarm information.

• For drive faults:

– The keypad shows the fault code.

– illuminates continuously.

– The drive shuts off output and the fault relay output activates. The motor coasts to stop.

• For drive alarms:

– The keypad shows the alarm code.

– flashes.

– Usually, the drive will continue to operate the motor. Some alarms let you select a motor stopping method.

■ Fault Reset

1. Remove the cause of the fault or alarm.

2. While the keypad is showing the fault or alarm code, push (RESET) or on the keypad.

This table lists the most frequent faults and alarms with possible causes and solutions. Refer to the Technical Manual for a full list of faults and alarms.
