4 Faults and alarms
4.2 List of faults and alarms
Remedy: For fault value, bit 0 = 1:
- correct encoder cable connected?
- check the plug connections of the encoder cable.
- SMC30: Check the parameterization (p0404.22).
For fault value, bit 1 = 1:
- correct encoder cable connected?
- replace the encoder or encoder cable.
For fault value, bit 2 = 1:
- correct encoder cable connected?
- replace the encoder or encoder cable.
For fault value, bit 3 = 1:
- correct encoder cable connected?
- replace the encoder or encoder cable.
For fault value, bit 5 = 1:
- Measuring unit correctly connected at the converter?
- Replace the measuring unit or the cable to the measuring unit.
For fault value, bit 6, 7 = 1:
- Replace the defective EnDat 2.2 converter.

F31121 (N, A) Encoder 1: Coarse position error
Message value: -
Message class: Actual position/speed value incorrect or not available (11)
Drive object: B_INF, ENC, VECTOR_G
Component: Encoder 1 Propagation: LOCAL
Reaction: Vector: ENCODER (NONE)
Infeed: NONE
Acknowledge: PULSE INHIBIT
Cause: For the actual value sensing, an error was detected on the module.
As a result of this error, it must be assumed that the actual value sensing supplies an incorrect coarse position.
See also: p0491 (Motor encoder fault response ENCODER)
Remedy: Replace the motor with DRIVE-CLiQ or the appropriate Sensor Module.

F31122 Encoder 1: Internal power supply voltage faulty
Message value: %1
Message class: Supply voltage fault (undervoltage) (3)
Drive object: B_INF, ENC, VECTOR_G
Component: Sensor Module Encoder 1 Propagation: GLOBAL
Reaction: Vector: ENCODER
Infeed: NONE
Acknowledge: IMMEDIATELY
Cause: Fault in internal reference voltage of ASICs for encoder 1.
Fault value (r0949, interpret decimal):
1: Reference voltage error.
2: Internal undervoltage.
3: Internal overvoltage.
Remedy: Replace the motor with DRIVE-CLiQ or the appropriate Sensor Module.
