Description of Diagnostic Letters B..., C..., D... and A... ECODRIVE03 SMT-02VRS
DOK-ECODR3-SMT-02VRS**-WA01-EN-P
Cause:
1. External encoder cable defective.
2. Defective feedback.
3. Defective measurement system interface.
Note: If this warning occurs in combination with an EnDat feedback
device then the feedback device is defective.
Remedy:
For 1. Check the optional feedback cable.
For 2. Exchange feedback.
For 3. Exchange the measuring system interface (module).

phase 4 transition check".
C223 Input value for max. range too high
Cause:
An internal position resolution has been selected via the S-0-0278,
Maximum travel range parameter that no longer guarantees a correct
commutation of the motor.
Remedy:
Select a smaller value for the S-0-0278, Maximum travel range
parameter.

phase 4 transition check".
C227 Modulo range error
Cause:
The marginal conditions for modulo processing were not maintained.
See functional description: "Modulo Processing-Limiting Conditions".
C234 Encoder combination not possible
Cause:
The encoder interface that has been selected in the P-0-0075, Interface
Feedback 2, optional parameter cannot be supported by the drive; it has
already been allocated to the motor encoder.
Remedy:
Select another optional encoder.
