2.12.4 Torque setpoint / additional torque setpoint

MCTRL_nMAdd_a is − depending on the setting of MCTRL_bNMSwt_b − used as a torque setpoint

or as an additional torque setpoint.

Torque setpoint

With MCTRL_bNMSwt_b = TRUE, the torque control is active.

 MCTRL_nMAdd_a acts as a torque setpoint.

 The speed controllers have a monitoring effect.

 The torque setpoint is selected in [%] of the max. possible torque.

– Negative values mean a torque with CCW rotation of the motor.

– Positive values mean a torque with CW rotation of the motor.

 The max. possible torque is set under C0057:

Additional torque setpoint

With MCTRL_bNMSwt_b = FALSE, the speed control is active.

 MCTRL_nMAdd_a is added to the output of the speed controller.

 The limits given by the torque limitation (MCTRL_nLoMLim_a and MCTRL_nHiMLim_a) cannot

be exceeded.

 The additional torque setpoint can, for instance, be used for friction compensation or to add

acceleration (dv/dt).
