Brush Length Too Short; Poor Bearing Condition - Siemens SINAMICS DCM List Manual

Alarm value (r2124, interpret binary):
Bit 0 = 1: CUD digital output 0 (X177.19) is overloaded
Bit 1 = 1: CUD digital output 1 (X177.20) is overloaded
Bit 2 = 1: CUD digital output 2 (X177.21) is overloaded
Bit 3 = 1: CUD digital output 3 (X177.22) is overloaded
Bit 4 = 1: CUD digital output 4 (X177.15) is overloaded
Bit 5 = 1: CUD digital output 5 (X177.16) is overloaded
Bit 6 = 1: CUD digital output 6 (X177.17) is overloaded
Bit 7 = 1: CUD digital output 7 (X177.18) is overloaded
Note:
The fault value is equal to the inverted value of parameter r53021. Information about short-circuit monitoring for the
individual digital outputs for further interconnection is available here.
Remedy: Check the overloaded digital outputs and rectify the overload or short circuit.

Brush length too short

Message value: -
Message class: General drive fault (19)
Drive object: DC_CTRL
Reaction: OFF2 (NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: A motor brush length which is too short has been reported via a binector input (p50486) for a period exceeding a
permanently set delay time.
Note:
This message is also reported via binector output r53120.0.
Remedy: - Check binector input p50486 and trace the generation of the signal back to the sensor.
- Check and if necessary update the motor's brush length.

Poor bearing condition

Message value: -
Message class: General drive fault (19)
Drive object: DC_CTRL
Reaction: OFF2 (NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: A defective motor bearing has been reported via a binector input (p50487) for a period exceeding a permanently set
delay time.
Note:
This message is also reported via binector output r53120.1.
Remedy: - Check binector input p50487 and trace the generation of the signal back to the sensor.
- Check and if necessary restore the motor's bearing condition.
