This menu is accessible when the access locking switch is in the total

unlock, , position. The parameters can only be modified when the

motor is stopped.

100% corresponds to the nominal torque of a motor with horsepower size equal to that

of the drive controller at its constant torque rating.

= drive controller constant torque output current rating shown on the drive controller

nameplate.
