ABB ACSM1 - Torq Ref Mod

Parameters and firmware blocks
176
Firmware block:
TORQ REF MOD
(33)
This block
• selects the source for the torque
reference
• scales the input torque reference
according to the defined load share
factor
• defines limits for the torque
reference
• defines ramp-up and ramp-down
times for the torque reference
• shows the ramped torque reference
value and the torque reference
value limited by the rush control.

32.03 TORQ REF IN FW block: TORQ REF MOD (see above)
Selects the source for the torque reference input for the torque ramp function. The default value is
P.3.9, ie, signal 3.09 TORQ REF1, which is the output of the TORQ REF SEL firmware block.
Value pointer: Group and index
32.04 MAXIMUM TORQ REF FW block: TORQ REF MOD (see above)
Defines the maximum torque reference.
0…1000% Maximum torque reference.
32.05 MINIMUM TORQ REF FW block: TORQ REF MOD (see above)
Defines the minimum torque reference.
-1000…0% Minimum torque reference.
32.06 LOAD SHARE FW block: TORQ REF MOD (see above)
Scales the external torque reference to a required level (external torque reference is multiplied by the
selected value).
Note: If local torque reference is used, no load share scaling is applied.
-8…8 External torque reference multiplier.
32.07 TORQ RAMP UP FW block: TORQ REF MOD (see above)
Defines the torque reference ramp-up time, ie, the time for the reference to increase from zero to the
nominal motor torque.
0…60 s Torque reference ramp-up time.
