10.4 Causes and Corrective Actions
Alarm Display
AL001：Over current
Causes Checking Method Corrective Actions
The drive output is short-
circuit
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 with Delta
The control parameter
setting is in error.
Check if the setting value exceeds
the default setting
Setting back to the default setting
and then gradually adjust the value.
Unreasonable command
Check if the command doing
reasonable acceleration time.
Less steep command used or filter
applying to smooth command.
AL002：Over voltage
Causes Checking Method Corrective Actions
The input voltage of the
main circuit is higher
than the rated allowable
voltage.
Use the voltmeter to see if the input
voltage of the main circuit is within
the rated allowable voltage value.
(please refer to Chapter 12.1)
Apply to the correct power supply
or serial voltage regulator.
Wrong power input
(incorrect power
system)
Use the voltmeter to see if the
power system matches the
specification.
Apply to the correct power supply
or serial adaptor.
The hardware of the
servo drive is damaged.
Use the voltmeter to see if the input
voltage of the main circuit is within
the rated allowable voltage value
but still shows the error.
Send the drive back to the
distributors or contact with Delta.
AL003：Under voltage
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.
Apply to the correct power supply
or serial adaptor.
