n 1: Standard
Standard gain adjustment is performed. In addition to gain adjustment,
notch filters and anti-resonance control are automatically adjusted.
n 2: For positioning
Tuning is performed for positioning applications. In addition to gain adjust-
ment, model following control, notch filters, anti-resonance control, and
vibration suppression are automatically adjusted.
n 3: For positioning especially to prevent overshooting
Tuning is performed for positioning applications with emphasis on elimi-
nating overshooting. In addition to gain adjustment, notch filters, antireso-
nance control, and vibration suppression are automatically adjusted.
3 - Mechanism selection Box
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 guide-
lines.
n 1: Belt mechanism
Tuning is performed for a mechanism with relatively low rigidity, e.g., a belt.
n 2: Ball screw mechanism or linear motor
Tuning is performed for a mechanism with relatively high rigidity, e.g., a ball
screw or Linear Servomotor. Use this setting if there is no other appropriate
setting.
n 3: Rigid model
Tuning is performed for a mechanism with high rigidity, e.g., a rigid body
system.
4 - Distance Box
Set the travel distance.
Movement range: -99,990,000 to +99,990,000 [reference units]
Minimum setting increment for travel distance: 1,000 [reference units]
Negative values are for reverse operation and positive values are for forward
operation from the current position.
Default settings:
Rotary Servomotors: Approx. 3 rotations
Direct Drive Servomotors: Approx. 0.3 rotations
Linear Servomotors: Approx 90 mm
Set the distance to the following values or higher. To ensure tuning precision,
we recommend that you use approximately the default distance setting.
Rotary Servomotors: 0.5 rotations
Direct Drive Servomotors: 0.05 rotations
Linear Servomotors: 5 mm
5 - Tuning parameters Box
Specify the parameters to use for tuning.
If you select the Start tuning using the default settings Check Box, the tuning
parameters will be returned to the default settings before tuning is started.
