ECODRIVE03 SMT-02VRS Description of Diagnostic Letters B..., C..., D... and A... 4-15
DOK-ECODR3-SMT-02VRS**-WA01-EN-P
Remedy:
For 1. Check the measurement system cable.
For 2. Exchange the measurement system.

phase 4 transition check".
C220 Feedback 1 initializing error
A number of tests are performed when the motor encoder is initialized. An
error was 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
Cause:
1. Defective motor feedback cable
2. Defective motor feedback
3. Defective measurement system interface
Remedy:
For 1. Check the motor feedback cable.
For 2. Exchange the motor.
For 3. Exchange the measuring system interface, if it is a module, or the
complete drive controller.

phase 4 transition check".
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
