◆ Auto-Tuning Fault Detection
Auto-Tuning faults in this section are displayed on the digital operator 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 End error on the digital operator display indicates Auto-Tuning has successfully completed with discrepancies in
the calculations. Check the cause of the End error using the tables in this section and perform Auto-Tuning again after
fixing the cause.
The drive may be used in the application if no cause can be identified despite the existence of an End error.
An Er 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.
