Delta AL065 fault code meaning

Delta / AL065

Series: ASDA-W3

servo drive

Meaning: The absolute position stored in the drive has been lost.

Condition: The absolute position stored in the drive has been lost. The home coordinates must be re-established. The causes are recorded in the high-order alarm bits, with each bit indicating a different cause. Causes: ◼Bit 0: Absolute home coordinates were not established after changing P1.001.Z. ◼Bit 1: Absolute home coordinates have not been established after changing the electronic gear ratio (P1.044, P1.045). ◼Bit 2: Reserved. ◼Bit 3: The homing program is incomplete. ◼Bit 4 ~ Bit 7: Reserved. ◼Bit 8: Absolute home coordinates were not established after changing P2.069 or resetting the parameters. ◼Bit 9: The value stored in drive EEPROM has been lost. ◼Bit 10: The value stored in drive EEPROM has been lost (third-party encoder and indexing without overflow function). ◼Bit 11 ~ Bit 15: Reserved.
