Set the operating mode for realtime autotuning.
Explanation of Settings
*1
Refer to
Realtime Autotuning Customization Mode Setting
on page 9-47 for setting the realtime autotuning
function (3632 hex).
Refer to
on page 11-7 for details of realtime autotuning settings.
*1
The default setting is 11 for a Drive with 200 V and 1 kW or greater, or for a Drive with 400 V.
•
Set the machine rigidity to one of 32 levels when realtime autotuning is enabled.
•
The higher the machine rigidity set value is, the higher the responsiveness is, however, the more
vibration occurs.
•
Refer to
on page 11-7 for details of realtime autotuning settings.
Precautions for Correct Use
Precautions for Correct Use
If the set value is changed suddenly by a large amount, the gain may change rapidly, subjecting
the machine to shock. Always start with a small setting, and gradually increase the setting while
monitoring machine operation.

Realtime autotuning is disabled.
1
Focus on stability
(default setting)
No unbalanced load, friction compensation, or gain switching.
2
Focus on position
control
Used when there is no unbalanced load and a little friction.
3
Unbalanced load
mode
Used when an unbalanced load is present.
4
Friction
compensation and
unbalanced load
mode
Used when there is an unbalanced load and a large friction.
Variations in the positioning stabilization time are suppressed when friction
is large.

Reserved
Do not set.

Customization
This mode is used for customizing the realtime autotuning function by
using the Realtime Autotuning Customization Mode Setting (3632 hex).
