DOK-ECODR3-SGP-03VRS**-WA01-EN-P
C221 Feedback 2 initializing error
Several checks are performed during the initialization of an optional
encoder. An error has been detected during this process. This error may
be:
• Error while reading the angle rectification data
• Error while copying the angle rectification data
• Interruption of communication with the encoder
• Assembly error with the position of an initialization track
• Error while reading the analog signal of an initialization track
• Error in the pointer length of the analog signal of an initialization track
• Invalid offset between the high and low resolution track
• Error in the measuring system micro-controller
• With DAG 1.2: external 24V set for SSI interface
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.

C227 Modulo range error
Cause:
The marginal conditions for modulo processing were not maintained.
See functional description: "Modulo Processing-Limiting Conditions".
