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.

parameter groups 3.10 TORQ REF RAMPED (page 101 )
3.11 TORQ REF RUSHLIM (page 101 )
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.
