Auto-Tuning Fault Detection - YASKAWA L1000A Quick Start Manual

5 Troubleshooting

◆ 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.
