Er - 02
Auto-Tuning Alarm
Yaskawa · F7 Drive
What does Er - 02 mean?
An alarm has been detected during the Auto-Tuning process, signaling a potential issue with the tuning setup or the motor/load configuration. While not a critical fault that stops the Drive, it warns of an incomplete or inaccurate auto-tuning result, which could lead to suboptimal motor performance or control issues.
Complete Troubleshooting Guide
- 1
Re-check all Auto-Tuning input data parameters (T1 group) for any incorrect or missing entries.
- 2
Inspect the output wiring from the Drive to the motor for any loose connections, damage, or improper phasing.
- 3
Evaluate the motor's mechanical load to ensure it is suitable for Auto-Tuning, considering temporarily disconnecting the load if possible.
