Auto-Tuning Fault Detection - YASKAWA Z1000U Technical Manual

6.7 Auto-Tuning Fault Detection

6.7 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 Endo error on the digital operator 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.
