7) When P03-01=”5”, the variable gain is applied based on the ON/OFF status of external control
gain conversion contact point. At this time, the conversion time of the control gain is decided.

[ Characteristics of individual controller ]
a) PI speed controller
: It has excellent acceleration/deceleration and good responsiveness characteristics but can
cause large overshoot.
b) IP speed controller
: It has lower acceleration/deceleration and responsiveness characteristics compared to the
PI speed controller, but it can suppress the overshoot to reduce the vibration.
You can adjust the controller set ratio with the desired performance by considering the
responsiveness and overshoot.
♥ P03-02 = 100 : Applied to PI speed controller
P03-02 = 0 : Applied to IP speed controller
