Equipment Hazard
Only perform Rotational Auto-Tuning with the motor disconnected from the load (ropes removed from traction
sheave).
Failure to comply will cause the drive will be unable to automatically set motor parameters correctly. This will result in
erroneous operation.
Do not check or test control circuit signals while the drive is running.
Improper use of test equipment could result in damage to the drive circuitry by short circuit.
Do not use the Rescue Operation feature for extended periods.
Failure to comply may result in drive heat sink overtemperature alarms (oH).
Set parameter E1-01 to match the input voltage of the drive. The drive input voltage (not motor voltage) must
be set in E1-01 for the protective features to function properly.
Failure to set the correct drive input voltage may result in improper drive operation.
Use the drives Torque Detection function to notify the PLC of potential overcurrent or overload situations at the
load prior to a drive overload fault.
Failure to comply may cause the drive to fault leaving the motor coasting, potentially damaging equipment.
Correctly set parameter o2-04 when replacing the control terminal board.
Failure to comply may result in drive damage due to lack of protective functions and poor drive performance.
