14.2 Causes and corrective actions

AL001 Overcurrent

Condition: main circuit current is greater than 1.5 times the maximum instantaneous

Trigger condition

and cause

current of the servo drive.

Cause:

1. The servo drive output is short-circuited.

2. Motor wiring is in error.

3. IGBT is abnormal.

1. Check the connection between the motor and servo drive and make sure that

the wire is not short-circuited. Do not expose the metal part of the wiring.

Check if you have followed the wiring sequence for connecting the motor to

Checking method

the servo drive as described in this manual.

and corrective action 2. If the temperature of the heat sink is abnormal, send your servo drive back to

the distributor or contact Delta. Check if the set value of the parameter is

much greater than the default. It is recommended that you reset the parameter

to the factory default setting and then modify the setting gradually.

Cycle power on the servo drive.

AL002 Overvoltage

Trigger condition

and cause

Condition: main circuit voltage exceeds the rated value.

Cause:

1. The input voltage of the main circuit is higher than the allowable rated value.

2. Incorrect power input (incorrect power system).

3. Malfunction of the servo drive hardware.

4. Incorrect selection of the regenerative resistor or no connection to an external

regenerative resistor.

1. Use a voltmeter to check if the input voltage of the main circuit is within the

allowable rated value (refer to Appendix A Specifications) and check if the

power system complies with the specifications. Use the right voltage source or

connect the transformer and regulator in series to have the voltage be within

Checking method

the specified range.

and corrective action 2. If the alarm occurs when the input voltage of the main circuit measured by the

voltmeter is within the allowable rated value, send your servo drive back to the

distributor or contact Delta.

3. 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.
