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, 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.
