Select the type according to the machine element to drive.
If there is noise or if the gain does not increase, better results may be obtained by changing the rigidity
type. Select the type according to the following guidelines.
The tuning modes that you can select depend on the SERVOPACK setting.
Mode Selection
Description
0: Set servo gains
with priority given
to stability.
This setting gives priority to stability
and preventing overshooting. In addi-
tion to gain adjustment, notch filters
and anti-resonance control are
adjusted.
1: Set servo gains
with priority given
to response.
Overshooting may occur because pri-
ority is given to response. In addition to
gain adjustment, notch filters and anti-
resonance control are adjusted.
2: Set servo gains
for positioning
application.
Tuning is performed for positioning
applications. In addition to gain adjust-
ment, notch filters, anti-resonance
control, and vibration suppression are
adjusted.
3: Set servo gains
especially to pre-
vent overshooting
during positioning
application.
Tuning is performed for positioning
applications with emphasis on elimi-
nating overshooting. In addition to gain
adjustment, notch filters, anti-reso-
nance control, and vibration suppres-
sion are adjusted.
Mechanism Selection
Description
1: Belt mechanism
Tuning is performed for a mechanism with relatively low rigidity, e.g., a belt.
2: Ball screw mechanism
Tuning is performed for a mechanism with relatively high rigidity, e.g., a ball screw. Use
this setting if there is no other appropriate setting.
3: Rigid body system
Tuning is performed for a mechanism with high rigidity, e.g., a rigid body system.
