Auto-Tuning Errors
n Auto-Tuning Codes
Auto-Tuning faults in this section are displayed on the HOA keypad and will cause the motor to coast to a stop. Auto-Tuning
faults do not trigger a multi-function digital output set for fault or alarm output.
An Endo error on the HOA keypad display indicates Auto-Tuning has successfully completed with discrepancies in the
calculations. Restart Auto-Tuning after fixing the cause of the Endo error.
The drive may be used in the application if no cause can be identified despite the existence of an Endo error.
An Ero error indicates that Auto-Tuning has not completed successfully. Check for the cause of the error using the tables in
this section, and perform Auto-Tuning again after fixing the cause.

HOA keypad display has turned off.
When an "SC" error occurs, contact Yaskawa or a Yaskawa agent before cycling the power to the drive.
