N/A

How to clear the

alarm?

Replace the motor immediately.

AL083 Servo drive outputs excessive current

Trigger condition

and cause

Condition: during general operation, this alarm occurs when the servo drive outputs

current that is over the allowable level specified by the firmware. This alarm protects

IGBT from overheating or burning because of the high current.

Cause:

1. UVW is short-circuited.

2. Motor wiring is in error.

3. The analog signal GND for the servo drive is interfered.

1. Check the the motor power cable and its connector.

If metal wire is exposed or the wire is torn, the UVW can short-circuit.

In this case, replace the power cable to avoid a short circuit.

2. Refer to Chapter 3 Wiring and check the following items:

Checking method

and corrective action

(a) If you do not use the Delta standard power cable, make sure the UVW

wiring sequence is correct.

(b) Make sure the UVW wiring between the servo drive and motor is correctly

connected.

3. Check if the analog signal GND is mistakenly connected to another ground

signal (incorrect connection can cause interference). Do not use a common

ground for the analog signal GND and other signal cables. Follow the wiring

instructions in Chapter 3.

AL085 Regeneration setting error

Trigger condition

and cause

Condition: regeneration control error.

Cause: regenerative resistor is not operating, but the regenerative voltage remains

at 400V for a period of time.

Checking method

and corrective action

Check the connection for the regenerative resistor, re-calculate the value for the

regenerative resistor, and correctly set the values of P1.052 and P1.053.

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