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 areas 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.
WARNING! When performing Rotational Auto-Tuning for motor data or PG encoder offset, always uncouple the motor from the
mechanical system (remove ropes from traction sheave). Performing Rotational Auto-Tuning with the mechanical system connected to
the motor can cause hazardous situations, injury to personnel and damage to the equipment.
NOTICE: Rotational Auto-Tuning will not function properly if a holding brake is applied on the load. Ensure the motor can freely spin
before beginning Auto-Tuning. Failure to comply could result in improper operation of the drive.
Enter the required information from the motor nameplate. Press
to proceed to the Auto-Tuning start display.
Note: These instructions continue from Step 6 in “Enter Data from the Motor Nameplate”.
