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.
AL004:
Motor combination error
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
AL005:
Regeneration error
Causes
Checking Method
Corrective Actions
Choose wrong
regenerative
resistor or does not
connect to external
regenerative
resistor
Check the connection of regenerative
resistor.
Calculate the value of the
regenerative resistor again
and correctly set the value of
P1-52 and P1-53. If issue
persists, please send the
drive back to the distributors
or contact Delta.
Parameter P1-53 is
not set to zero
when the
regenerative
resistor is not in
use.
Check if parameter P1-53 of
regenerative resister is set to zero.
Set parameter P1-53 of
regenerative resistor to zero
when it is not applying.
Wrong parameter
setting
Check the setting value of parameter
P1-52 and P1-53.
Correctly reset the value of
P1-52 and P1-53.
