Note 1. Normally select feedback-value integral PID control as the derivative control
method.
Note 2. Add the frequency reference if the target of control is motor speed and do not
add the frequency reference if the target of control is temperature or pressure.
Note 3. Set positive or negative characteristics according to the characteristics of the
detector. If the feedback value is decreased with the output frequency
increased, set negative characteristics.
