6. GENERAL GAIN ADJUSTMENT
6.2 Gain adjustment methods
The gain adjustment in this section can be made on a single driver. For the gain adjustment, refer to (3) in this
section.
One-touch tuning
Gain adjustment method
Parameter No.
PA08 setting
Estimation of load to
motor inertia moment
ratio
Automatically set
parameters
Manually set parameters
Operation of the one-touch
tuning button (AUTO) on
the front panel of the
driver
(Refer to section 6.1.)
Automatically
changes to "000",
when the value
before the one-
touch tuning is
"000" or "001".
"003", when the
value before the
one-touch tuning
is "003".
