Cause: The encoder error word provides detailed information (error bit).
Fault value (r0949, int
erpret binary):
yyyyxxxx hex: yyyy = supplementary information, xxxx = fault cause
Bit 0: Error in the multiturn block.
Bit 1: EEPROM error.
Bit 2: Singleturn position incorrect.
Bit 3: Multiturn position incorrect.
Bit 4: MLS generation error.
Bit 5: Reserved.
Bit 6: Overtemperature.
Bit 7: Internal fault.
Remedy: Encoder is defective. Replace the encoder or motor.
F31112 Motor encoder: Encoder signals an internal error
Message class: Position/speed actual value incorrect or not available (11)
Message value: %1
Component: Encoder 1
Response: ENCODER
Acknowledgment: PULSE INHIBIT
Cause: The encoder signals an internal error via serial protocol.
F
ault value (r0949, int
erpret binary):
Bit 0: Fault bit in the position protocol.
Remedy: For fault value, bit 0 = 1:
In the case of an EnDat encoder, F31111 ma
y provide further details.
F31150 Motor encoder: Initialization error
Message class: Error in the parameterization / conguration / commissioning pr
ocedure (18)
Message value: %1
Component: Sensor Module Encoder 1
Response: ENCODER
Acknowledgment: PULSE INHIBIT
Cause: Encoder functionality selected in p0404 cannot be executed.
F
ault value (r0949, int
erpret hexadecimal):
Encoder malfunction.
The bit assignment corresponds to that of p0404 (e.g. bit 5 set: Error track C/D).
See also: p0404 (Encoder conguration eective)
Remedy: - Check that p0404 is correctly set.
- Check the encoder type used (incr
emental/absolute) and for SMCxx, the encoder cable.
- If relevant, note additional fault messages that describe the fault in detail.
A31407 Motor encoder: Function limit reached
Message class: Position/speed actual value incorrect or not available (11)
Message value: %1
Component: Encoder 1
Response: NONE
Acknowledgment: NONE
