Quick Mode; Auto Tuning - Delta ASDA-A3 Series User Manual

Tuning

5.2 Quick mode

Quick mode is the default mode for the servo drive. In most applications, you can start the servo
5
drive after it is installed. Please note that the gain related parameter settings are invalid when
starting in Quick mode. You can enable or disable Quick mode with P2.033. When switching to
Auto Tuning mode, Quick mode is automatically disabled.

5.3 Auto tuning

The Auto Tuning function provided by the ASDA-A3 enables the system to perform real-time
machine inertia estimation and upload the corresponding tuning parameters to the servo drive.
You can start auto tuning with ASDA-Soft (software) or at the drive panel. The following table lists
the parameters that change according to the results of auto tuning.
