Setting Method For Quick Tuning - Mitsubishi Electric MELSERVO J5 Series User Manual

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 one-touch tuning with the following procedures.
■When executing quick tuning at the initial servo-on after turning on the power
1.
Switch to the servo-off status.
2.
Set "5" (quick tuning) to [Pr. PA08.0].
3.
Set "0" (at the initial servo-on after cycling the power) to [Pr. PA08.5].
4.
Check the load to motor inertia ratio.
• When the load to motor inertia ratio is 30 times or less
Set "0" (a load to motor inertia ratio of 30 times or less) to [Pr. PA08.4].
• When the load to motor inertia ratio is over 30 times and 100 times or less, or unknown
Set "1" (a load to motor inertia ratio of 100 times or less) to [Pr. PA08.4].
5.
Set the permissible travel distance for quick tuning with [Pr. PA34].
6.
Switch to the servo-on status to adjust servo parameters automatically.
Quick tuning will be executed at every initial servo-on after turning on the power thereafter.
7.
Set "6" (load to motor inertia ratio monitor mode) to [Pr. PA08.0] to retain the tuning results.
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: A load to motor inertia ratio of 30 times or less
1: A load to motor inertia ratio of 100 times or less
Set when to execute quick tuning. The initial value is "0".
0: At the initial servo-on after cycling the power (Execute quick tuning at the initial servo-on after
turning on the power)
1: At every servo-on (Execute quick tuning every time the SON is turned on.)
Set the permissible travel distance in quick tuning.
If the travel distance in quick tuning exceeds the setting value, the quick tuning error occurs.
When "0" is set, the permissible travel distance of quick tuning is 1.0 rev (10 mm when using a
linear servo motor).
Setting range: 0 to 100
