2: AutoMode (The ratio of Load Inertia to servo motor inertia is fixed)

The ratio of Load Inertia to servo motor inertia is set by parameter P1-37.

The level of stiffness and responsiveness are adjusted by parameter P2-31.

•Control Loop Structure Settings:

0:PDFF Control. PDFF : Pseudo-Derivative Feedback and Feedforward

1:PI Control. PI : Proportional - Integral control

Explanation of Auto-tuning:

1.When switching mode #1 to #2 or #0, the system will save the measured load inertia value automatically and memorized in P1-37 and related gain parameters.

2.In AutoMode #1, the system will save the measured load inertia value every 30 minutes automatically and memorized in P1-37.

3.In AutoMode #2, if the setting value of P2-31 changes, the related gain parameters will also change. However, the setting value of P1-37 will retain its value.

4.When switching mode #2 to #0, it indicates the setting of P1-37 and all settings of related gain parameters will be returned to original setting value in #0 manual mode.

5.No matter in Manual mode #0 or in AutoMode #2, the users should enter the appropriate load inertia value in P1-37.

6.If the users use the servo dynamic auto-tuning function of ASDA-B software (Tools Æ Servo Tuning Æ Dynamic Auto tuning), it will save the measured load inertia value and memorized in P1-37 and related gain parameters.
