ALE 6 / ALE : Overload
„ When the motor is started within 30 minutes:
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.
Check if there is mechanical vibration Adjust gain value of control circuit. Control system
parameter setting is
incorrect.
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.
The encoder of the
motor is damaged.
Please contact your distributor for assistance or contact with Delta.
The connection of U, V,
W is incorrect. Ensure the U, V, W of the motor is connected
to the U, V, W of the drive correctly.
Ensure all wiring is correct.
„ When the motor start running for 3 minutes above:
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.
Check if there is mechanical vibration Adjust gain value of control circuit. Control system
parameter setting is
incorrect.
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.
ALE 7 / ALE : Overspeed
„ When SERVO ON:
Potential Cause Checking Method Corrective Actions
The wiring of motor is
incorrect.
Check the wiring of U, V, W and encoder. Ensure all wiring is correct.
The encoder of the
motor is damaged.
Please contact your distributor for assistance or contact with Delta.
„ When the motor Accel/Decel in high-speed:
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).
