What is the PID Loop?
All PMAC controllers provide a PID position loop servo filter. For most applications, this filter is sufficient to control the system and easily understandable as well, even for non-control specialists. The filter is tuned by setting the appropriate parameter for each motor. For systems with more difficult dynamics, such as multiple resonances and low-frequency resonances, a generalized plant transfer function (pole placement filter) can be used instead of the PID filter.
