3.2.39 Internal motor control (MCTRL)

3−107

EDSVS9332S−EXT EN 2.0

3.2.39.5 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.

l MCTRL−M−ADD acts as bipolar torque setpoint.

l 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.

l 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.

3.2.39.6 Speed setpoint limitation

The speed setpoint is limited to ±100 % of nmax (C0011) at the MCTRL−N−SET input.

C0909 is used to set a limitation of the direction of rotation for the speed setpoint.
