Stiffness value
represents parameters with fixed value. Default for A to C-frame is 4, and 1 for D to F-frame.
*2 Lower limit for stiffness value is 10 for 17-bit encoder, and 25 for 2500P/r encoder.

Auto-Gain Tuning Action
(1) In the normal mode auto-gain tuning, you can set up the response with machine stiffness No..
Machine stiffness No.
• Represents the degree of machine stiffness of the customer's machine and have values from o to 15.
You can set a higher No. to the high stiffness machine and set up a higher gain.
• Usually start setting up with a lower value and increase gradually to repeat auto-gain tuning in the
range where no oscillation, no abnormal noise, nor vibration occurs.
(2) This tuning repeats max. 5 cycles of the action pattern set with SV.Pr25 (Normal auto tuning motion
setup). Action acceleration will be doubled every one cycle after third cycle. Tuning may finish, or action
acceleration does not vary before 5th cycle depending on the load, however, this is nor an error.
How to Operate
(1) Set up the action pattern with SV.Pr25.
(2) Shift the load to the position where no hazard is expected even though the action pattern which is set
with SV.Pr25 is executed.
(3) Prohibit the command entry. (Do not enter the action command during the normal mode auto-gain tuning.)
(4) Turn to Servo-ON.
(5) Start up the auto-gain tuning. Use the "PANATERM
® ".
(6) Adjust the machine stiffness to the level at which no vibration occurs and obtain the required response.
(7) Write the result to EEPROM, if it is satisfactory.
