Chapter 6 Control Modes of Operation
In general, the equipment, such as spectrum analyzer is needed and used to analyze
when using frequency domain method and the users also should have this kind of
analysis technology. However, when using time domain method, the users only need to
prepare an oscilloscope. Therefore, the general users usually use time domain method
with the analog DI/DO terminal provided by the servo drive to adjust what is called as PI
(Proportional and Integral) type controller. As for the performance of torque shaft load,
input command tracking and torque shaft load have the same responsiveness when using
frequency domain method and time domain method. The users can reduce the
responsiveness of input command tracking by using input command low-pass filter.
Auto Mode (Continuous adjustment))
This Auto Mode provides continuous adjustment of loop gains according to measured
inertia automatically. It is suitable when the load inertia is fixed or the load inertia change
is small and is not suitable for wide range of load inertia change. The period of
adjustment time is different depending on the acceleration and deceleration of servo
motor. To change the stiffness and responsiveness, please use parameter P2-31.
