ASDA-A2 Chapter 6 Control Mode of Operation
used to adjust PI controller. The abilities of PI controller to deal with the resistance of torque load
and the following command are the same.
That is to say, the following command and resistance of torque load have the same performance in
frequency domain and time domain. Users can reduce the bandwidth by setting the low-pass filter
in command end.
Auto Mode
Auto mode adopts adaptive principle. The servo drive automatically adjusts the parameters
according to the external load. Since the adaptive principle takes longer time, it will be unsuitable if
the load changes too fast. It would be better to wait until the load inertia is steady or changes
slowly. Depending on the speed of signal input, the adaptive time will be different from one another.
