Auto-Tuning Errors

This table gives information about errors detected during Auto-Tuning. If the drive detects an Auto-Tuning error,
the keypad will show the error and the motor will coast to stop. The drive will not send notification signals for
faults and alarms when Auto-Tuning errors occur.
Two types of Auto-Tuning errors are: Endx and Erx. Endx identifies that Auto-Tuning has successfully completed
with calculation errors. Find and repair the cause of the error and do Auto-Tuning again, or set the motor
parameters manually. You can use the drive in the application if you cannot find the cause of the Endx error.
Erx identifies that Auto-Tuning was not successful. Find and repair the cause of the error and do Auto-Tuning
again.

13 Troubleshooting
Possible Solutions
Remove the function settings that are not in use.
Set the parameters correctly.
Possible Solutions
• Make sure that the input motor nameplate data is correct.
• Do Auto-Tuning again and correctly set the motor nameplate
data.
• If you can uncouple the motor and load, remove the motor
from the machine and do Rotational Auto-Tuning again.
• If you cannot uncouple the motor and load, use the results
from Auto-Tuning.
• Make sure that the input motor nameplate data is correct.
• Do Auto-Tuning again and correctly set the motor nameplate
data.
Do Auto-Tuning again and set the correct rated current shown on
the motor nameplate.
• Make sure the input motor nameplate data is correct.
• Do Rotational Auto-Tuning again and correctly set the motor
nameplate data.
• If you cannot uncouple the motor and load, do Stationary
Auto-Tuning 2.
• Make sure that the input motor nameplate data is correct.
• Examine and repair damaged motor wiring.
