Delta AL058 fault code meaning

Delta / AL058

Series: ASDA-A3

Position error too large after initial field detection at power-on is complete

servo drive

Meaning: 1. After initial field detection is complete, the servo system attempts to reduce the existing position error but fails. 2. If the host controller issues commands before the servo has settled, the servo position error increases and cannot converge.

Possible causes

Conditions:
After initial field detection is complete, the servo system attempts to reduce the existing position error but fails.
If the host controller issues a command before servo settling is complete, the servo position error increases and cannot converge. Cause: The host controller issues a command during detection.

Series: ASDA-W3

Position error too large after initial field detection at power-on is complete

servo drive

Meaning: After power-on, initial field detection is performed at the first Servo On in position mode. The motor moves during detection. After initial field detection is complete, the drive cannot return the motor to its position at power-on.

Possible causes

Condition: After power-on, initial field detection is performed at the first Servo On in position mode. The motor moves during detection. After initial field detection is complete, the drive cannot return the motor to its position at power-on. Cause:
The host controller issues a position command during field detection.
The control gain is too high, causing resonance or system divergence.
Check whether interference causes the pulse encoder to lose pulses, affecting position control.
The field detection time is too long.
