Chapter 9 Troubleshooting ASDA-B2
9-4 Revision September 2013
: Motor error
Potential Cause Checking Method Corrective Actions
Encoder is damage. Check Encoder for the damage. Repair or replace the motor.
Encoder is loose. Examine the Encoder connector. Install the motor again.
The type of the servo
motor is incorrect.
Check if the servo drive and servo motor
are not correctly matched for size (power
rating).
Replace the motor.
: Regeneration error
Potential Cause Checking Method Corrective Actions
Regenerative resistor
is not connected.
Check the wiring connection of
regenerative resistor.
Reconnect regenerative resistor.
Regenerative switch
transistor fault
Check if regenerative switch transistor is
short-circuited.
Please contact your distributor
for assistance or contact with
Delta.
Parameter setting is
in error
Confirm the parameter setting and
specifications of regenerative resistor.
Correctly reset parameter again.
: Overload
Potential Cause Checking Method Corrective Actions
The drive has
exceeded its rated
load during
continuous operation.
Check if the drive is overloaded.
Increase motor capacity or
reduce load.
Control system
parameter setting is
incorrect.
Check if there is mechanical vibration
Adjust gain value of control
circuit.
Accel/Decel time setting is too fast.
Decrease Accel/Decel time
setting.
The wiring of drive
and encoder is in
error.
Check the wiring of U, V, W and encoder. Ensure all wiring is correct.
: Overspeed
Potential Cause Checking Method Corrective Actions
Speed input
command is not
stable (too much
fluctuation).
Use signal detector to detect if input signal
is abnormal.
Ensure that input command
frequency is stable (not
fluctuate too much) and
activate filter function (P1-06,
P1-07 and P1-08).
Over-speed
parameter setting is
defective.
Check if over-speed parameter setting
value is too low.
Correctly set over-speed
parameter setting (P2-34).
