Parameters Details
Set the OPERATING mode for realtime autotuning.
Refer to "10-3 Realtime Autotuning (P.10-6)".
Explanation of Set Values
*1.It 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 "10-3 Realtime Autotuning (P.10-6)".
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 the small setting, and gradually increase the setting while
monitoring machine operation.

Description
0 Disabled
1 This mode focuses on stability.
2
This mode focuses on positioning.
It is used for a horizontal axis, for example, which has only a small friction without any load
unbalance, such as for a ball screw drive.
In the speed control or the torque control, it is same as the set value 1 which focuses on
stability.
3
This mode focuses on positioning.
It is used for a vertical axis which has unbalanced load.
In the torque control, it is same as the set value 1 which focuses on stability.
4
Used when friction is large.
It shortens the positioning stabilization time when the friction is large, such as for a belt drive.
In the speed control, it is same as the set value 3. In the torque control, it is same as the set
value 1.
5 It is used for a vertical axis which has a large friction and unbalanced load.
6
It is used for customizing the realtime autotuning function by the REALTIME AUTOTUNING
CUSTOMIZATION mode Setting (Pn632).
