Arm Cur Max
Overload current. Max. permissible armature current
in % related to the nominal motor current (1.01).
In dependent of the sign, applies to either direction.
Directional limitations are set in par. Torque Lim Pos

Torque Lim Pos
Positive overload torque. Max. permissible positive
torque in % related to the nominal torque.
(The nominal torque is defined as the torque
resulting from nominal field current and nominal
armature current)
The torque reference is limited as a function of the
sign. The current resulting from this operation is
then limited in parameter

values will be effective.
Is also used as positive current limitation if

Torque Lim Neg
Negative overload torque. Max. permissible
negative torque in % related to the nominal torque.
(The nominal torque is defined as the torque
resulting from nominal field current and nominal
armature current)
Limits the torque reference as a function of the sign.
The current resulting from this operation is then
limited in par.
