Functions, monitoring, and protective functions
9.2 Drive functions
Signal connections
The holding brake is controlled using free digital outputs on the Control Unit or the TM31 (for
option G60). If necessary, control must be realized by means of a relay to connect a holding
brake with higher voltage or with higher power demand.
For this, parameter p1215 must be set to "3" (motor holding brake the same as sequence
control, connection via BICO) and the appropriate BICO parameters of the selected digital
outputs must be interconnected.
Commissioning
If p1215 is set to "0" (no brake available) during initial commissioning and a connected brake
is recognized, simple brake control is activated automatically (p1215 = 1). In this case, fault
F07935 "Motor holding brake detected" appears and must be acknowledged.
NOTICE
Material damage due to a destroyed brake for an incorrectly set configuration
If a motor holding brake is being used, the parameter setting p1215 = "0" (no motor holding
brake available) means that the motor holding brake remains closed. The brake will be
destroyed when the motor moves.
• If there is a motor brake, set parameter p1215 to values > 1.
Notes on setting the release (opening) time (p1216):
● The release time (p1216) should be set longer than the actual release time of the holding
brake. As a result, the drive will not accelerate when the brake is closed.
Notes on setting the closing time (p1217):
● The closing time (p1217) should be set longer than the actual closing time of the holding
brake. As a result, the pulses are suppressed only after the holding brake is closed.
● If the closing time (p1217) is set too low compared to the actual closing time of the
holding brake, the load may drop suddenly.
● If the closing time (p1217) is set too high compared to the actual closing time of the
holding brake, the controller acts against the holding brake and thus reduces its service
life.
