10.8.6 Motor torque monitoring
This funcon limits the motor torque during operaon.
Precondions
The motor torque monitoring can only be used for the following motor control types with
speed controller:
•
Servo control (SC ASM)
•
Sensorless control (SL PSM)
•
Sensorless vector control (SLVC)
Details
This funcon sets the internal status signal "Torque limit reached [79]" = TRUE when the maxi-
mum possible torque has been reached.
The limits of the monitoring funcon are selected via 0x2949:001 (P337.01) (posive torque
limit) and 0x2949:002 (P337.02) (negave torque limit). The actual limits can be seen in
0x2949:003 (P337.03) (actual posive torque limit), 0x2949:004 (P337.04) (actual negave
torque limit).

The selected response takes place if the status signal "Torque limit
reached [79]" = TRUE and the deceleraon me set in 0x2D67:002
(P329.02) has elapsed.
