AL095 Regenerative resistor is disconnected

2. If not using the regenerative resistor, set P1.053 (Regenerative resistor capacity)

to 0.

If the issue persists, send your servo drive back to the distributor or contact Delta.

DI.ARST

AL099 DSP firmware error

Trigger condition

and cause

EEPROM is not reset after DSP firmware is updated.

Checking method Check if the firmware is updated. If so, set P2.008 to 30 first and then set it to 28.

and corrective action Next, cycle power on the servo drive. Contact Delta if this error persists.

How to clear the

alarm?

Set P2.008 to 30 and then 28. Cycle power on the servo drive.

AL09C Parameter reset failed

Trigger condition

and cause

Condition: the parameter reset process is not complete.

Cause: an error occurred during the parameter reset process, so the reset

procedure could not be completed.

Checking method Check if the power is cut off during the reset process. Check the power wiring and

and corrective action switch.

How to clear the

alarm?

Set P2.008 to 30 and then 28. Cycle power on the servo drive.

AL0A6 Absolute positions of the servo drive and motor do not match

Trigger condition

and cause

Condition: suppose there are servo drive A, servo motor A, servo drive B, and

servo motor B. Servo drive A and servo drive B have established the absolute

origin positions with servo motor A and servo motor B respectively. In this case, if

you operate servo drive A with servo motor B, AL0A6 will be triggered.

Cause: the servo drive or servo motor is changed.

Checking method

and corrective action

Re-establish the absolute origin positions.

How to clear the

alarm?

Re-establish the absolute origin positions.
