You can tune the servo drive by following this flowchart. First, start from One Touch Tuning.

If you are not satisfied with the tuning results, then use Auto Tuning, Gain Tuning, and Manual

mode in sequence to meet the requirements.

Description

When you use the functions of One Touch Tuning, Auto Tuning, or Gain adjustment

mode 1 (Level adjustment - Auto) with ASDA-Soft, the servo drive automatically estimates

the load inertia or weight during the tuning process. You can also perform the estimation

with the Inertia (Weight) Estimation function. Whether the load inertia ratio or total

weight (P1.037) is correctly set affects the speed loop bandwidth of the servo drive.

You must use the One Touch Tuning function with ASDA-Soft. During the tuning

process, the motor slightly moves and makes high-frequency noise. For the detailed

operation procedure, refer to Section 5.3.

You can use the Auto Tuning function with ASDA-Soft or through the panel. The

command source can be the servo drive or the controller. During the tuning process, the

drive controls the motor to run back-and-forth between the two positioning points. For the

detailed operation procedure, refer to Section 5.4.

The servo provides five gain adjustment modes (not including Manual mode and Gain

adjustment mode 4 (Reset to the default gain values)), which is set with P2.032. For the

detailed operation procedure and parameter adjustment, refer to Section 5.5.

In Manual mode (P2.032 = 0), users can fine-tune all the gain parameters for optimal

performance of the machine. For the detailed parameter adjustment, refer to Sections 5.6

and 5.7.
