The currently active torque limit values are displayed in the following parameters:
r0067
Maximum drive output current
r1526
Torque limit, upper/motoring without offset
r1527
Torque limit, lower/regenerative without offset
All of the following limits act on the torque setpoint – that is either available at the speed
controller output for closed-loop speed control or as torque input, for closed-loop torque
control. The minimum or the maximum is used for the various limits. This minimum or
maximum is cyclically calculated and is displayed in r1538 or r1539.
r1538
Upper effective torque limit
r1539
Lower effective torque limit
These cyclical values therefore limit the torque setpoint at the speed controller output/torque
input or indicate the instantaneous max. possible torque. If the torque setpoint is limited, then
this is displayed using parameter p1407.
r1407.8
Upper torque limit active
r1407.9
Lower torque limit active
Current/power/torque limits
