Auto-Tuning Errors

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.

Fault Reset Methods

When a fault occurs, the cause of the fault must be removed and the drive must be restarted. The table below lists the different

ways to restart the drive.

After the Fault Occurs

Fix the cause of the fault, restart the drive, and

reset the fault.

Resetting via Fault Reset Digital Input S4

Turn off the main power supply if the above methods do not reset the fault. Reapply power after the

HOA keypad display has turned off.

When an "SC" error occurs, contact Yaskawa or a Yaskawa agent before cycling the power to the drive.

Note:

If the Run command is present, the drive will disregard any attempts to reset the fault. Remove the Run command before attempting to clear

a fault situation.
