Sudden Movement Hazard
Ensure all personnel are clear of the motor and elevator before Auto-Tuning.
The motor or equipment may suddenly rotate during the Auto-Tuning process, which may result in serious personal
injury or death.
The drive is capable of running the motor at high speed. Verify the maximum drive output frequency before
starting the drive.
Failure to comply may cause injury or death due to inadvertent high speed operation.
Verify drive parameter b1-03 Stopping Method is set to 0:Ramp to Stop before starting the drive.
Failure to comply may cause the elevator to free-fall when the Up/Down command is removed.
System may start unexpectedly upon application of power when the Auto-Reset function is enabled resulting in
death or serious injury.
Use care when enabling Auto-Reset as this function may cause unintended start of the elevator.
Ensure holding brake circuits are properly configured, load equipment may fall or drop during power loss or
drive fault, which could result in death or serious injury.
• Provide a separate holding brake if necessary.
• Always construct the external sequence to confirm that the holding brake is activated in the event of an emergency, a
power failure, or an abnormality in the drive.
• If using the drive with an elevator, provide safety measures on the elevator to prevent the elevator from dropping.
Install additional emergency circuits separately from drive fast stop circuits.
Failure to comply may result in personal injury.
Remove the Up/Down Command before resetting alarms and faults.
Failure to comply can result in death or serious injury.
The drive and motor may start unexpectedly during Auto-Tuning, which could result in death or serious injury.
• Remove main power from the drive before servicing the drive or motor.
• Do not touch the motor during Auto-Tuning.
• Ensure the area surrounding the drive motor and load are clear before proceeding with Auto-Tuning.
System may start unexpectedly, resulting in death or serious injury.
Before starting or applying power to the drive, clear all personnel from the drive, motor and machine area and check
sequence and safety circuitry. Secure covers, couplings, shaft keys and machine loads.
Electrical Shock Hazard
Do not operate equipment with covers removed.
Failure to comply could result in death or serious injury.
The diagrams in this section may include drives without covers or safety shields to illustrate details. Be sure to reinstall
covers or shields before operating the drives and run the drives according to the instructions described in this manual.
Do not remove covers or touch circuit boards while the power is on.
Failure to comply could result in death or serious injury.
CAUTION
Burn Hazard
Do not touch a hot drive heatsink.
Failure to comply could result in minor or moderate injury. Shut off the power to the drive when replacing the cooling
fan. To prevent burns, wait at least 15 minutes and make sure heatsink has cooled down.
