ASDA-B2
AL003:
Under voltage
Causes
The input voltage of
the main circuit is
lower than the rated
allowable voltage.
No power supply
for the main circuit.
Wrong power input
(incorrect power
system)
AL004:
Motor combination error
Causes
The encoder is
damaged.
The encoder is
loose.
Motor Combination
Error
AL005:
Regeneration error
Causes
Choose wrong
regenerative
resistor or does not
connect to external
regenerative
resistor
Parameter P1-53 is
not set to zero
when the
regenerative
resistor is not in
use.
Wrong parameter
setting
Revision May, 2018
Checking Method
Check if the input voltage wiring of the
main circuit is normal.
Use the voltmeter to see if the voltage
of the main circuit is normal.
Use the voltmeter to see if the power
system matches the specification.
Checking Method
The encoder is abnormal.
Check the encoder connector.
Connect to the right motor.
Checking Method
Check the connection of regenerative
resistor.
Check if parameter P1-53 of
regenerative resister is set to zero.
Check the setting value of parameter
P1-52 and P1-53.
Chapter 9 Troubleshooting
Corrective Actions
Re-confirm the voltage wiring.
Check the power switch
Apply to the correct power
supply or serial adaptor.
Corrective Actions
Change the motor
Install the motor again.
Change the motor
Corrective Actions
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.
Set parameter P1-53 of
regenerative resistor to zero
when it is not applying.
Correctly reset the value of
P1-52 and P1-53.
