Si Mm: Fault In The Shutdown Path Of The Second Channel - Siemens Sinamics S120 Diagnostic Manual

SINAMICS alarms
81: SafeBrakeAdapter: Fault in "brake closed" state.
82: SafeBrakeAdapter: Fault in "open brake" state.
83: SafeBrakeAdapter: Fault in "close brake" state.
84,85:
SafeBrakeAdapter: Fault in the brake control circuit of the Control Unit or communication fault between 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.
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 cable routing are in compliance with EMC regulations (e.g. shield of the
motor cable and brake conductors are connected with the shield connecting plate and the motor connectors are tightly
screwed to the housing).
- replace the Motor Module involved.
Operation with Safe Brake Module or Safe Brake Adapter:
- check the Safe Brake Module or Safe Brake Adapter connection.
- Replace the Safe Brake Module or Safe Brake Adapter.

230640 <location>SI MM: Fault in the shutdown path of the second channel
Message value: %1
Drive object: AFE_SINUMERIK_828, BIC_SINUMERIK_828, SERVO_COMBI, SERVO_SINUMERIK828, SIC_COMBI,
SIC_SINUMERIK_828
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The Motor Module has detected a communications error with the higher-level control or the TM54F to transfer the
safety-relevant information.
Note:
This fault results in a STOP A that can be acknowledged.
Fault value (r0949, interpret decimal):
Only for internal Siemens troubleshooting.
Remedy: For the higher-level control, the following applies:
- check the PROFIsafe address in the higher-level control and Motor Modules and if required, align.
- save all parameters (p0977 = 1).
- carry out a POWER ON (power off/on) for all components.
For TM54F, carry out the following steps:
- start the copy function for the node identifier (p9700 = 1D hex).
- acknowledge hardware CRC (p9701 = EC hex).
- save all parameters (p0977 = 1).
- carry out a POWER ON (power off/on) for all components.
The following generally applies:
- upgrade the Motor Module software.
