Delta EcSc fault code meaning

Series: C2000 Plus, CH2000

Encoder single-turn error

AC motor drive

Meaning: The accumulated single-turn position reported by the encoder is incorrect.

Possible causes

• Encoder single-turn position accumulation error
• 1. Immediate stop
• 2. For each returned position sample, if a single-turn count error occurs sporadically, the AC motor drive performs position interpolation.
• 3. If the AC motor drive consecutively receives errors (single-turn count error, encoder open, encoder communication error)
• An error is reported when the total exceeds 5 occurrences. The reported error code is the code of the last error. The error can be reset directly after it is reported.
