11.3 Safety messages for SINAMICS S120
F30630 SI P2: Brake control defective
● 30: Fault for "Close brake"
Brake not connected or interrupted cable (check whether for p1278 = 1 and p9602/p9802 = 0 (SBC
switched-out) the brake opens).
Short-circuit in the brake winding
● 40: Fault in the "Brake closed" state
● 60, 70: Fault in the brake control of the Control Unit or communication error between the Control Unit
and Motor Module (brake control).
● 81: Safe Brake Adapter: Fault for "Brake closed".
● 82: Safe Brake Adapter: Fault for "Open brake".
● 83: Safe Brake Adapter: Fault for "Close brake".
● 84, 85: Safe Brake Adapter: Fault in the brake control of the Control Unit or communication error between
the Control Unit and Motor Module (brake control).
● 90: Brake released for service purposes (X4).
● 91: Fault for "Open brake".
Brake not connected or interrupted cable (check whether for p1278 = 1 and p9602/p9802 = 0 (SBC
deactivated) the brake opens).
Remedy Check parameter p1278 (with SBC, only p1278 = 0 is permissible)
● Select Safe Torque Off and then deselect again.
● Check the connection of the motor holding brake.
● 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 control cabinet is EMC-compliant and the cable routing (e.g. connect the motor cable
shield and brake conductors with the shield connecting plate or screw the motor connector to the
enclosure).
● Replace the Motor Module involved.
Operation with Safe Brake Module or Safe Brake Adapter:
● Check the connection of the Safe Brake Module or Safe Brake Adapter.
Replace the Safe Brake Module or Safe Brake Adapter.
A30640 (F) SI P2: Fault in the switch-off signal path of the second channel
Response OFF2
Acknowledg‐ IMMEDIATELY (POWER ON)
ment
Explanation The Motor Module has a communication error with the higher-level control to transfer the safety-relevant
information, or there is a communication error between Motor Modules connected in parallel.
Note:
This fault results in a STOP A that can be acknowledged.
Fault value (r0949, interpret as decimal):
Only for internal Siemens troubleshooting.
