SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) - - 10.2015 Edition
$MA_SAFE_BRAKETEST_CONTROL
Extended settings for the brake test
Min. input limit: 0
Protection level: 7/2
Extended settings for the NC- -controlled 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).
See Chapter 7.6: "Safe brake test (SBT)"

Reference quantity for the holding torque, brake test
Min. input limit: - -
Protection level: 7/0
Setting the reference quantity for torques.
All of the torques specified as relative value refer to this reference quantity.
This MD involves an image of drive parameter p2003.
Max. input limit: 3
Max. input limit: - -
