12.28.4 Setting of motor control
12.28.4.1 Torque setpoint
ƒ The maximum possible torque is calculated from the motor parameters by the
controller. It can be read in C0057.
ƒ Torque setpoint "torque setpoint"#
– TORQUE−MCTRL.MAdd (C7531/1) acts as a torque setpoint.
– The speed controllers carry out a monitoring function.
– The torque setpoint is defined in [%] of the maximum possible torque.
– Negative values cause a torque in CCW rotation of the motor.
– Positive values cause a torque in CW rotation of the motor.
12.28.4.2 Torque limitation
An external torque limitation can be set via TORQUE−MCTRL.NegLoMLim (C7531/3) and
TORQUE−MCTRL.HiMLim (C7531/4). This enables you to select different torques for the
quadrants "driving" and "braking".
ƒ TORQUE−MCTRL.HiMLim is the limit in the positive direction in [%] of the maximum
possible torque.
ƒ TORQUE−MCTRL.HoMLim is the limit in the negative direction in [%] of the
maximum possible torque.
The maximum possible torque (C0057) depends on the motor parameters (C0022, C0081,
C0087, C0088).

Note!
In case of quick stop (QSP), the torque limitation is switched to an inactive
state, i. e. the operation runs with ±100 %.
