One-Touch Tuning - Mitsubishi Electric MR-J4-10A(-RJ) Instruction Manual

6. NORMAL GAIN ADJUSTMENT

6.2 One-touch tuning

The one-touch tuning includes two methods: the user command method and the amplifier command method.
(1) User command method
You can execute the one-touch tuning with MR Configurator2 or push buttons. The user command
method performs one-touch tuning by inputting commands from outside the servo amplifier.
(2) Amplifier command method
You can execute the one-touch tuning with MR Configurator2. 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. PA21 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]
will be estimated.
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 in the amplifier command method, MR
Configurator2 is required.
For MR-J4-03A6(-RJ) servo amplifier, one-touch tuning by the amplifier
command method is not available.
