Code 207930: <location>Drive: Brake control error

Message value: %1 Drive object: SERVO, VECTOR Reaction: OFF1 (NONE, OFF2, OFF3) Acknowledge: IMMEDIATELY Cause: The Control Unit has detected a brake control error. Fault value (r0949, interpret decimal): 10, 11: Fault in "open holding brake" operation. - No brake connected or wire breakage (c heck whether brake releases for p1278 = 1). - Ground fault in brake cable. 20: Fault in "brake open" state. - Short-circuit in brake winding. 30, 31: Fault in "close holding brake" operation. - No brake connected or wire breakage (c heck whether brake releases for p1278 = 1). - Short-circuit in brake winding. 40: Fault in "brake closed" state. 50: Fault in the brake control circuit of the Control Un it or communication fault between the Control Unit and Motor Module (brake control). Note: The following causes may apply to fault values: - motor cable is not shielded correctly. - defect in control circuit of the Motor Module. See also: p1278 (Brake control, diagnostics evaluation) SINAMICS-Alarms Diagnostics Manual (DAsl), 03/2009 Remedy: - check the motor holding brake connection. - check the function of the motor holding brake. - check whether there is a DRIVE-CLiQ communication error between the Control Unit and the Motor Module involved and, if required, carry out a diagnostics routine for the faults identified. - check that the electrical cabinet design and cabl e routing are in compliance with EMC regulations (e.g. shield of the motor cable and brake conduct ors are connected with t he shield connecting plate and the motor connectors are tightly screwed to the housing). - replace the Motor Module involved. Operation with Safe Brake Module: - check the Safe Brake Modules connection. - replace the Safe Brake Module.
