Number / Fault Cause
F051 - Signal amplitude of resolver or encoder is
below the tolerance threshold
Encoder fault - In the case of multiturn encoders (SSI/Endat)
connection fault of the serial protocol
- In the case of multiturn encoders (SSI/Endat)
connection fault of the serial protocol

Counter-measure
Resolver/encoder
fault value r949:
9 = Resolver signal missing
25 = Encoder initial position not recognized
(C/D track missing from V1.32)
- Check encoder cable (faulty / interrupted)?
- Correct encoder type parameterized?
- Is the correct cable used for encoder or
multiturn encoder? Encoders and multiturn
encoders need different cables!
- Encoder faulty?
26 = Encoder zero pulse outside the permitted
range
27 = No encoder zero pulse has occurred
28 = Voltage supply Encoder fault
- Short-circuit in encoder connection?
- Encoder faulty?
- Encoder incorrectly connected up?
!!!Power off/on or in drive settings and back to
new initialization of the starting position!!!
29 = Encoder/ multiturn encoder signal is
missing
And encoder starting position not reccognized
(C/D track missing to V1.31)
- Check encoder cable (faulty/torn off)?
- Is shield of encoder cable connected ?
- Encoder faulty?
- Replace SBR/SBM
- Replace unit or basic board
- Is the correct cable being used in each case
for the encoder/multiturn encoder?' Encoders
and multiturn encoders require different
encoder cables!
!!!Power off/on or in drive settings and back to
new initialization of the starting position!!!
Multiturn (SSI/EnDat):
Fault value r949:
30: Protocol fault CRC/Parity Check
31: Timeout Protocol (EnDat)
32: Neutral level fault
33: Initialization of timeout
- Check parameterization (P149)
- Check encoder cable (faulty / torn off?
- Encoder cable shield connected ?
- Encoder faulty?
- Replace SBR/SBM
- Replace unit or basic board
34: Address wrong (only EnDat)
Writing or reading of parameters not
successful, check address and MRS code
(P149)
40-48: Encoder alarms (only EnDat)
Check voltage supply to encoder, battery
change on battery-backed-up systems,
encoder faulty
49: Alarm bit set
Parameterization (P149), Encoder alarm
50-59: Alarms EnDat encoder
Fault value + 100 designates the
corresponding faults of the external encoder.
