AL011 Encoder erro
Cleared after re-power on
Causes Checking Method Corrective Actions
Wrong wiring of the encoder Check if the wiring follows the
suggested wiring in the user manual.
Correct wiring
The encoder is loose. Check the CN2 connector of the drive
and the encoder connector.
Install the encoder again.
Bad connection of the
encoder
Check if the connection between CN2
connector of the drive and the encoder
of the servo motor is loose.
Reconnect the wiring.
The encoder is damaged. Check if the motor is damaged. Change the motor.
AL012 Adjustment erro
N/A
Causes Checking Method Corrective Actions
Abnormal current adjustment Reset power supply. If the error still occurs after reset,
send the drive back to the
distributors or contact with Delta.
AL013 Emergency stop
Automatically cleared after DI.EMGS is OFF
Causes Checking Method Corrective Actions
The emergency stop button
is pressed.
Check if the emergency stop button is
enabled.
Release emergency stop button.
AL014 Reverse limit error
Cleared by DI.ARST, Servo Off or after motor
operates backwards
Causes Checking Method Corrective Actions
Reverse limit switch is
activated.
Check if the reverse limit switch is
activated.
Release the reverse limit
switch.(e.g. motor operates
backwards)
AL015 Forward limit error
Cleared by DI.ARST, Servo Off or after motor
operates backwards
Causes Checking Method Corrective Actions
Forward limit switch is
activated.
Check if the forward limit switch is
activated.
Release the forward limit
switch.(e.g. motor operates
backwards)
AL016 IGBT overheat
Cleared by DI.ARST
Causes Checking Method Corrective Actions
Over the rated loading of the
drive and continuously
excessive using
Check if the drive is overloading or the
motor current is too high.
Increase the motor capacity or
reduce the load.
The drive output is
