ALE 11 / ALE : Encoder error (Position detector fault)
Potential Cause Checking Method Corrective Actions
The wiring of encoder is
in error.
1. Check if all wiring is correct.
2. Check if the users conduct the wiring by
the wiring information in the user manual.
Ensure all wiring is correct.
Encoder is loose Examine the encoder connector. Install the motor again.
The wiring of encoder is
defective.
Check if all connections are tight. Conduct the wiring again.
Encoder is damage Check the encoder for the damage. Repair or replace the motor.
ALE 12 / ALE : Adjustment error
Potential Cause Checking Method Corrective Actions
The motor is running. Check if the motor is running. Turn off the motor.
Analog input contact
does not correctly
return to zero. Measure and check if the voltage level of
analog input contact is the same as the
electrical potential of grounding.
Correctly ground analog input
contact.
Detection device may
be damaged.
Check and reset the power supply.
Please contact your distributor for
assistance or contact with Delta.
ALE 13 / ALE : Emergency stop activated
Potential Cause Checking Method Corrective Actions
Emergency stop switch
is activated.
Check if emergency stop switch is On or Off. Activate emergency stop switch.
ALE 14 / ALE : Reverse (CWL) limit switch error
Potential Cause Checking Method Corrective Actions
Reverse limit switch is
activated.
Check if reverse limit switch is On or Off. Activate reverse limit switch.
Servo system is not
stable. Check the value of control parameter setting
and load inertia. Modify parameter setting and re-
estimate motor capacity.
ALE 15 / ALE : Forward (CCWL) limit switch error
Potential Cause Checking Method Corrective Actions
Forward limit switch is
activated.
Check if forward limit switch is On or Off. Activate forward limit switch.
Servo system is not
stable. Check the value of control parameter setting
and load inertia. Modify parameter setting and re-
estimate motor capacity.
