Part 5: Common Reference Material
(4) One-touch tuning
The one-touch tuning includes two methods: the user command method and the amplifier command
method.
1) User command method
The user command method performs one-touch tuning by inputting commands from outside the
servo amplifier.
2) Amplifier command method
In the amplifier command method, when you simply input a travel distance (permissible travel
distance) that collision against the equipment does not occur during servo motor driving, a
command for the optimum tuning will be generated inside the servo amplifier to perform one-
touch tuning.
POINT
After the one-touch tuning is completed, "Gain adjustment mode selection" in [Pr.
PA08] will be set to "2 gain adjustment mode 2 (_ _ _ 4)". To estimate [Pr. PB06
Load to motor inertia ratio/load to motor mass ratio], set "Gain adjustment mode
selection" in [Pr. PA08] to "Auto tuning mode 1 (_ _ _ 1)".
When executing the one-touch tuning, check the [Pr. PX13 One-touch tuning
function selection] is "_ _ _1" (initial value).
At start of the one-touch tuning, only when "Auto tuning mode 1 (_ _ _ 1)" or "2
gain adjustment mode 1 (interpolation mode) (_ _ _ 0)" of "Gain adjustment
mode selection" is selected in [Pr. PA08], [Pr. PB06 Load to motor inertia
ratio/load to motor mass ratio] will be estimated.
Execute the one-touch tuning while the servo system controller and the servo
amplifier are connected.
When executing the one-touch tuning in the test operation mode (SW2-1 is on),
write the tuning result to servo parameters of the servo system controller, and
then connect the servo system controller and the servo amplifier.
The amplifier command method can be used with the servo amplifier with
software version C1 or later and MR Configurator2 with software version 1.45X
or later.
When the one-touch tuning is executed, MR Configurator2 is required.
