n Starting Auto-Tuning
WARNING! Sudden Movement Hazard. The drive and motor may start unexpectedly during Auto-Tuning, which could result in death or
serious injury. Ensure the area surrounding the drive motor and load are clear before proceeding with Auto-Tuning.
WARNING! Electrical Shock Hazard. High voltage will be supplied to the motor when Stationary Auto-Tuning is performed even with the
motor stopped, which could result in death or serious injury. Do not touch the motor until Auto-Tuning has been completed.
NOTICE: Rotational Auto-Tuning will not function properly if a holding brake is engaged on the load. Failure to comply could result in improper
operation of the drive. Ensure the motor can freely spin before beginning Auto-Tuning.
Enter the required information from the motor nameplate. Press to proceed to the Auto-Tuning start display.
