Current controller
Adapt current controller via C0075 (proportional gain) and C0076 (reset time) to the machine
connected.
Tip!
Set a suitable motor from the selection table "Motors" under C0086.
With this the parameters of the current controller are automatically set correctly.
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).
•
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.
•
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.
•
The torque setpoint is defined in [% ] of the max. possible torque (see code C0057).
– Negative values mean a torque with CCW rotation of the motor.
– Positive values mean a torque with CW rotation of the motor.
