Message value: %1 Drive object: All objects Reaction: OFF2 Acknowledge: IMMEDIATELY (POWER ON) Cause: The drive-based "Safety Integrated" function on the Motor Module (MM) has detected a brake control error and initiated a STOP A. Fault value (r0949, interpret decimal): 10: Fault in "open holding brake" operation. - Parameter p1278 incorrectly set. - No brake connected or wire breakage (c heck whether brake releases for p1278 = 1 and p9602/p9802 = 0 (SBC deactivated)). - Ground fault in brake cable. 30: Fault in "close holding brake" operation. - No brake connected or wire breakage (c heck whether brake releases for p1278 = 1 and p9602/p9802 = 0 (SBC deactivated)). - Short-circuit in brake winding. 40: Fault in "brake closed" state. 60, 70: 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. SINAMICS-Alarms Diagnostics Manual (DAsl), 03/2009 Remedy: - check parameter p1278 (for SBC, only p1278 = 0 is permissible). - select Safe Torque Off and de-select again. - 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. Note: MM: Motor Module SBC: Safe Brake Control SI: Safety Integrated
