3.5.43.1 Current controller

Adapt current controller via C0075 (proportional gain) and C0076 (reset time) to the machine

connected.

) Note!

Use C0086 to select a suitable motor from the motor selection list. In this way, the

parameters of the current controller are automatically set to the correct values.

3.5.43.2 Additional torque setpoint

The input MCTRL−M−ADD serves as torque setpoint or additional torque setpoint, depending on the

control of the input MCTRL−N/M−SWT. The additional torque setpoint can be used e.g. for friction

compensation or speed injection (dv/dt).

l When MCTRL−N/M−SWT = LOW the speed control is active.

– MCTRL−M−ADD is added to the output of the n−controller.

– The limits defined by the torque limitations MCTRL−LO−M−LIM and MCTRL−HI−M−LIM

cannot be exceeded.

l When MCTRL−N/M−SWT = HIGH, the torque control is active.

– MCTRL−M−ADD acts as torque setpoint

– The n−controllers have a monitoring function.

l The torque setpoint is specified in [%] of the max. possible torque (see C0057).

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

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