The value specifies the maximum permissible torque whereby different limits can be
parameterized for motor and regenerative mode.
•

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 the following parameters:
•
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 the following parameters:
•
r1407.8 Upper torque limit active
•
r1407.9 Lower torque limit active
