Delta AL04D fault code meaning

Series: ASDA-W3

Absolute linear encoder data write error

servo drive

Meaning: When an absolute linear encoder is used with a linear motor, an error occurs while writing absolute position data to the drive's EEPROM, and a data error is detected during power-on detection.

Possible causes

• Condition: When an absolute linear encoder is used with a linear motor, an error occurs while writing absolute position data to the drive's EEPROM, and a data error is detected during power-on detection. Cause: An error may have occurred in EEPROM.
