Arm Cur Max
Overload current. Max. permissible armature current
in % related to the nominal motor current (1.01).
Independent of the sign, applies to either direction.
Directional limitations are set in par. Torque Lim Pos
(3.07) and Torque Lim Neg (3.08).

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 Arm Cur Max (3.04)
independent of the sign i.e. the smaller the two
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. Arm Cur Max (3.04) independent of
the sign i.e. the smaller the two values will be
effective.
Is also used as negative current limitation if
