Chapter 10 Troubleshooting ASDA-A2
Revision February, 2017 10-11
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
The regenerative resistor
is unconnected or too
low
Check the connection of
regenerative resistor.
Reconnect the regenerative resistor
or calculate the value of the
regenerative resistor.
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 setting.
AL006：Overload
Causes Checking Method Corrective Actions
Over the rated loading of
the drive and
continuously excessive
using
Set parameter P0-02 to 11 and see
if the average torque [%] is over
100% all the time.
Increase the motor capacity or
reduce the load.
The setting of the control
system parameter is
inappropriate.
1. Check if there is any mechanical
vibration.
2. Check if the acceleration /
deceleration constant are set too
fast.
1. Adjust the gain value of the
control circuit.
2. Slow down the acceleration /
deceleration setting time.
Wrong wiring of the
motor and the encoder.
Check the wiring of U, V, W and the
encoder.
Correct wiring
The encoder of the motor
is defective.
Send the drive back to the distributors or contact with Delta.
AL007：Overspeed
Causes Checking Method Corrective Actions
Unreasonable command
Use the scope to check if the signal
of analog voltage is abnormal.
Less steep command used or filter
applying to smooth command.
Inappropriate parameter
setting
Check if the setting of parameter
P2-34 is too small (the condition of
over-speed warning).
Correctly set parameter P2-34 (the
condition of over-speed warning).
