6.2 One-touch tuning
POINT
When executing the one-touch tuning, check the [Pr. PA21 One-touch tuning
function selection] is "_ _ _ 1" (initial value).
You can execute the one-touch tuning with MR Configurator2 or push buttons. The following parameters are
set automatically with one-touch tuning.

6.2.1 One-touch tuning flowchart
(1) When you use MR Configurator2
Make one-touch tuning as follows.
Startup a system referring to chapter 4.
Rotate the servo motor by an external controller, etc. (The one-touch tuning cannot be performed if the
servo motor is not operating.)
Start one-touch tuning of MR Configurator2.
Select a response mode (high mode, basic mode, and low mode) in the one-touch tuning window of
MR Configurator2.

Startup of the system
Operation

End
Push the start button to start one-touch tuning. Push it during servo motor driving.
When one-touch tuning is completed normally, the parameters described in table 6.1 will be set
automatically.
