Auto-Tuning Response
[ATRES] Setting range Unit Standard value
1 to 30 - 5
■
Sets the Auto-Tuning Response.
◆ The larger the set value, the higher the response.
◆
Caution, if the response is set too high, the machine may oscillate.
◆ Make the setting suitable for rigidity of the device.
03
Auto-Tuning Automatic Parameter Saving
[ATSAVE] Setting range unit Standard value
00 to 01 - 00:Auto_Saving
■
Select if the automatic parameter saving function is valid to save the Load inertia moment ratio
estimated by the Driver Auto-tuning function in the Group1 ID14 (JRAT1) Load Inertia Moment
Ratio 1.
◆ This setting is valid when Group0 ID00 Tuning Mode is at 00 AutoTun Auto-tuning
◆
The first automatic save is done after one (1) hour from the power input. Then automatic
save is done in every two (2) hours.

Auto-Notch Filter Tuning Torque Command
[ANFILTC]
Setting range Unit Standard value
10.0 to 100.0 % 50.0
■
Sets the torque value to excite the mechanical system during operation under
“
Auto-Notch Filter
Tuning.
”
✔
Larger value makes the tuning more accurate; however, note that it also makes the
movement of the machine greater.
20
Auto-FF Vibration Suppressor Frequency
Tuning Torque Command [ASUPTC]
Setting range Unit Standard value
10.0 to 100.0 % 25.0
■
Sets the torque value to excite the mechanical system during run time
“
Auto-FF Vibration
Suppressor Frequency Tuning.
”
✔
Larger value makes the tuning more accurate; however, note that it also makes the
movement of the machine greater.
21
Auto-FF Vibration Suppressor Frequency
Tuning Friction Compensation Value [ASUPFC] Setting range Unit Standard value
0.0 to 50.0 % 5.0
■
Sets the friction torque compensation added to the motor torque to excite the mechanical system at
the time of Auto-FF Vibration Suppressor Frequency Tuning.
◆ Set this value close to actual friction torque, and vibration suppressor frequency tuning will
be more accurate.
✔
When the set value is low, there may be cases that the vibration frequency of the
mechanical system cannot be detected, or the wrong value is detected. Raise the
value until the detected value settles.
