Torque control with speed limitation

This function is activated with MCTRL-N/M-SWT = HIGH. A second speed controller (auxiliary speed
controller) is connected for the speed limitation.
•
MCTRL-M-ADD acts as bipolar torque setpoint.
•
The n-controller 1 is used to create the upper speed limit.
– The upper speed limit is selected at the input MCTRL-N-SET in [% ] of nmax (C0011) (pos.
sign for CW rotation).
– The upper speed limit is only to be used for CW rotation.
•
The n-controller (auxiliary speed controller) is used to form the lower speed limit
– The lower speed limit is selected at the input MCTRL-N2-LIM in [% ] of nmax (C0011) (neg.
sign for CCW rotation).
– The lower speed limit is only to be used for CCW rotation.
7.5.60.6

Speed setpoint limitation

The speed setpoint in the MCTRL-N-SET input is limited to ±100 % of nmax (C0011).
C0909 is used to set a limitation of the direction of rotation for the speed setpoint.
