1242:8 Offset torque setpoint (open–loop torque
controlled) (SRM, ARM)
Offset force setpoint (open–loop torque con-
trolled) (SLM)
This parameter value is added to the torque setpoint or force setpoint (SLM).
Note:
Thus, a pre–tensioning torque can be generated.

Parameters
–50 000.0
In the constant torque range,
referred to the 1st torque limit (P1230)
Constant power range
referred to the first power limit (P1235)
Negative characteristic (P1244 = 1)
– Application
For wire breakage, the input voltage is 0 V
––> the limits for the torque/power are effective, defined with the
normalization (maximum values)
––> this case is suitable for applications which require a torque
when a fault occurs (e.g. hanging axes)
Positive characteristic (P1244 = 2)
– Application
For a wire breakage, a 0 V input voltage becomes effective
––> there is no torque/power
––> this case is suitable for applications which do not require
torque under fault/error conditions
