The following parameters are set automatically with one-touch tuning. Also, "Gain adjustment mode
selection" in [Pr. PA08] will be "2 gain adjustment mode 2 (_ _ _ 4)" automatically. Other parameters will
be set to an optimum value depending on the setting of [Pr. PA09 Auto tuning response].

(a) One-touch tuning flowchart
1) User command method
Make one-touch tuning as follows.
Start
Startup of the system
Operation
One-touch tuning start,
mode selection
Response mode selection
One-touch tuning execution
One-touch tuning completion
Tuning result check
One-touch tuning in progress
End
Start a system referring to chapter 4.
Rotate the servo motor by a servo system controller. (In the user command method, the one-
touch tuning cannot be executed if the servo motor is not operating.)
Start one-touch tuning of MR Configurator2, and select "User command method".
Select a response mode (High mode, Basic mode, and Low mode) in the one-touch tuning
window of MR Configurator2.
Click "Start" during servo motor driving to execute one-touch tuning.
Gains and filters will be adjusted automatically. During processing of tuning, the tuning progress
will be displayed in % in MR Configurator2.
When one-touch tuning is completed normally, the parameters described in table 17.5 will be
set automatically.
When the tuning is not completed normally, the tuning error will be displayed. (Refer to (4) (b) 5)
in this section.))
Check the tuning result.
When the tuning result is not satisfactory, you can return the parameter to the value before the
one-touch tuning or the initial value. (Refer to (4) (b) 8) in this section.))

2) Amplifier command method
Make one-touch tuning as follows.
Start
Startup of the system
Movement to tuning start position
One-touch tuning start,
mode selection
Input of permissible
travel distance
Response mode selection
One-touch tuning execution
One-touch tuning completion
Tuning result check
One-touch tuning in progress
Controller reset
Servo amplifier power cycling
End
Start a system referring to chapter 4.
Move the moving part to the center of a movable range.
Start one-touch tuning of MR Configurator2, and select "Amplifier command method".
In the one-touch tuning window of MR Configurator2, input a maximum travel distance to move
the moving part at one-touch tuning.
Select a response mode (High mode, Basic mode, and Low mode) in the one-touch tuning
window of MR Configurator2.
While the servo motor is stopped, click "Start" to start one-touch tuning. After the tuning is
started, the servo motor will reciprocate automatically. Executing one-touch tuning during servo
motor rotation will cause an error. After one-touch tuning is executed using the amplifier
command method, control will not be performed by commands from the controller.
Gains and filters will be adjusted automatically. During processing of tuning, the tuning progress
will be displayed in % in MR Configurator2.
One-touch tuning will be completed automatically after the tuning. When one-touch tuning is
completed normally, the parameters described in table 17.5 will be updated automatically.
When the tuning is not completed normally, the tuning error will be displayed. (Refer to (4) (b) 5)
in this section.))
Check the tuning result.
When the tuning result is not satisfactory, you can return the parameter to the value before the
one-touch tuning or the initial value. (Refer to (4) (b) 8) in this section.))
After executing the one-touch tuning, resetting the controller or cycling the power of the servo
amplifier returns to the state in which control is performed from the controller.
