Chapter 10 Troubleshooting
AL004：Motor Combination Error
Causes
The encoder is
damaged.
The encoder is loose.
Motor Combination Error Connect to the right motor.
AL005：Regeneration Error
Causes
The regenerative resistor
is unconnected or too
low
Parameter P1-53 is not
set to zero when the
regenerative resistor is
not in use.
Wrong parameter setting
AL006：Overload
Causes
Over the rated loading of
the drive and
continuously excessive
using
The setting of the control
system parameter is
inappropriate.
Wrong wiring of the
motor and the encoder.
The encoder of the motor
is defective.
AL007：Overspeed
Causes
Unreasonable command
Inappropriate parameter
setting
Revision February, 2017
Checking Method
The encoder is abnormal.
Check the encoder connector.
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.
Checking Method
Set parameter P0-02 to 11 and see
if the average torque [%] is over
100% all the time.
1. Check if there is any mechanical
vibration.
2. Check if the acceleration /
deceleration constant are set too
fast.
Check the wiring of U, V, W and the
encoder.
Send the drive back to the distributors or contact with Delta.
Checking Method
Use the scope to check if the signal
of analog voltage is abnormal.
Check if the setting of parameter
P2-34 is too small (the condition of
over-speed warning).
Corrective Actions
Change the motor
Install the motor again.
Change the motor
Corrective Actions
Reconnect the regenerative resistor
or calculate the value of the
regenerative resistor.
Set parameter P1-53 of
regenerative resistor to zero when
it is not applying.
Correctly reset the setting.
Corrective Actions
Increase the motor capacity or
reduce the load.
1. Adjust the gain value of the
control circuit.
2. Slow down the acceleration /
deceleration setting time.
Correct wiring
Corrective Actions
Less steep command used or filter
applying to smooth command.
Correctly set parameter P2-34 (the
condition of over-speed warning).
