$MA_SAFE_BRAKETEST_CONTROL
Extended settings for the NC-controlled and SINAMICS brake test.
Bit 0: Select the average value for the torque limiting
Bit 0 = 0:
Drive parameter p1532 is used as the average value of the torque limiting.
Bit 0 = 1:
The measured torque at the instant in time that the brake test is selected is used as the average
value of the torque limit.
Bit 1: Criterion for reaching the torque limit in the PLC
Bit 1 = 0: The torque limit value must be reached during the programed travel distance.
Bit 1 = 1: The torque limit value must be reached during the programmed time (PLC).
Bit 2: Selects the positioning response at the end of the SINAMICS brake test.
Bit 2 = 0: Positioning to the actual axis position
Bit 2 = 1: Positioning to the last programmed axis position
