◆ 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.
