9.4 Causes and Corrective Actions
AL001 Over current Cleared by DI.ARST
Causes Checking Method Corrective Actions
The drive output is
short-circuited. Check if the wiring between the motor
and the drive is correct and see if the
wire is short-circuited. Eliminate short-circuit and avoid
metal conductor being exposed.
The motor wiring is in error. Check if the wiring steps are correct
when connecting the motor to the drive. Rewiring by following the wiring
description from the user manual.
IGBT is abnormal. The temperature of the heat sink is
abnormal. Send the drive back to the
distributors or contact Delta.
The setting of control
parameter is in error. Check if the setting value exceeds the
default setting. Setting back to the default setting
and then gradually adjust the
value.
The setting of control
command is in error. Check if the command is doing
reasonable variation. Modify the switching rate of
issuing command or enable filter.
AL002 Over voltage Cleared by DI.ARST
Causes Checking Method Corrective Actions
The input voltage of the main
circuit is higher than the
rated allowable voltage. Use voltmeter to see if the input voltage
of the main circuit is within the rated
allowable voltage value. (please refer to
Appendix A) Connect to the correct power
supply or serial voltage regulator.
Wrong power input
(incorrect power system) Use voltmeter to see if the power
system matches with the specification. Connect to the correct power
supply or serial voltage
transformer.
The hardware of the servo
drive is damaged. Use voltmeter to see if the input voltage
of the main circuit is within the rated
allowable voltage value but the error still
occurs. Send the drive back to the
distributors or contact with Delta.
AL003 Under voltage Cleared when voltage returns to normal value
Causes Checking Method Corrective Actions
The input voltage of the main
circuit is lower than the rated
allowable voltage. Check if the input voltage wiring of the
main circuit is normal. Re-confirm the voltage wiring.
No power supply for the
main circuit Use the voltmeter to see if the voltage of
the main circuit is normal. Check the power switch.
Wrong power input
(incorrect power
system) Use the voltmeter to see if the power
system matches the specification. Connect to the correct power
supply or serial voltage
transformer.
AL004 Motor combination error Cleared after re-power on
Causes Checking Method Corrective Actions
The encoder is damaged. The encoder is abnormal. Change the motor.
The encoder is loose. Check the encoder connector. Install the motor again.
Motor combination error Connect to the right motor. Change the motor.
