Real time auto
tuning set up
You can set up the action mode of the real-time auto-gain tuning.
With higher setup such as 3 or 6, the driver respond quickly to the change
of the inertia during operation, however it might cause an unstable
operation. Use 1 or 4 for normal operation.For the vertical axis application,
use with the setup of 4 to 6.
When vibration occurs at gain switching, set up this to "7".

Normal auto tuning
motion setup
You can set up the action pattern at the normal mode auto-gain tuning.
e.g.) When the setup is 0, the motor turns 2 revolutions to CCW and 2
revolutions to CW.

Machine stiffness
at auto tuning
You can set up the machine stiffness in 16 steps while the real-time auto-
gain tuning is valid.
<Caution>
When you change the setup value rapidly, the gain changes rapidly as
well, and this may give impact to the machine. Increase the setup
gradually watching the movement of the machine.
