EDSVS9332P−EXT DE 2.0
3.5.43.5 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.
3.5.43.6 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.
