Series: ASDA-W3
Encoder read/write incomplete warning
servo drive
Meaning: When the drive sends a read/write command to the encoder, the encoder response times out, leaving the program incomplete.
Possible causes
- Condition: When the drive sends a read/write command to the encoder, the encoder response times out, leaving the program incomplete. Cause:
- Loose encoder wiring or poor contact causes a momentary encoder communication error.
- A source of interference causes a momentary encoder communication error.
- Encoder error: No response.
