Torq Ref Mod - ABB ACSM1 Firmware Manual

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.
Block outputs located in other
parameter groups
32.03 TORQ REF IN
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
Value pointer: Group and index
32.04 MAXIMUM TORQ REF
Defines the maximum torque reference.
0...1000%
32.05 MINIMUM TORQ REF
Defines the minimum torque reference.
-1000...0%
32.06 LOAD SHARE
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
32.07 TORQ RAMP UP
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
