Setting method for quick tuning

How to use quick tuning
Servo parameter Name
PA08.0 Gain adjustment mode selection
PA08.4 Quick tuning - Load to motor
inertia ratio setting
PA08.5 Quick tuning - Execution selection
PA34 Quick tuning - Permissible travel
distance
Execute quick tuning using the following procedure.
■When executing quick tuning at the initial servo-on after turning on the power
1.
Turn off servo-on.
2.
Set [Pr. PA08.0] to "5" (quick tuning mode).
3.
Set [Pr. PA08.5] to "0" (at initial servo-on after cycling the power).
4.
Check the load to motor inertia ratio.
• When the load to motor inertia ratio is 30 times or less
Set [Pr. PA08.4] to "0" (load to motor inertia ratio of 30 times or less).
• When the load to motor inertia ratio is over 30 times but not greater than 100 times, or unknown
Set [Pr. PA08.4] to "1" (load to motor inertia ratio of 100 times or less).
5.
Set the permissible travel distance for quick tuning with [Pr. PA34].
6.
Turn on servo-on to adjust servo parameters automatically.
Quick tuning is then executed at each initial servo-on every time the power is turned on.
7.
To retain the tuning results, set [Pr. PA08.0] to "6" (load to motor inertia ratio monitor mode).
Description
Select the gain adjustment mode. The initial value is "1".
0: 2 gain adjustment mode 1 (interpolation mode)
1: Auto tuning mode 1
2: Auto tuning mode 2
3: Manual mode
4: 2 gain adjustment mode 2
5: Quick tuning mode
6: Load to motor inertia ratio monitor mode
Select the load to motor inertia ratio of the equipment. The initial value is "0".
0: Load to motor inertia ratio of 30 times or less
1: Load to motor inertia ratio of 100 times or less
Set when to execute quick tuning. The initial value is "0".
0: At initial servo-on after cycling the power (Executes quick tuning at initial servo-on after turning
on the power.)
1: At every servo-on (Executes quick tuning every time servo-on is turned on.)
Set the permissible travel distance for quick tuning. The initial value is "0".
If the travel distance for quick tuning exceeds the setting value, the quick tuning error occurs.
When "0" is set, the permissible travel distance for quick tuning is 1.0 rev (10 mm when using a
linear servo motor).
Setting range: 0 to 100
