Operation mode switching is executed according to the motion setting
parameter Operation Mode Setting (OWC000 Bit0 ~ Bit4).
2. P/PI switching of the servo amplifier (SGDH) speed loop is possible
during operation.
A usage example is given below.
• To Suppress Overshoot During Acceleration
• To suppress Undershoot and Shorten Settling Time
Speed loop P/PI switching is executed according to the motion setup
parameter RUN Command (OBC0011).
3. Parameter change is possible during operation.
The following parameters can still be changed during operation by the ladder
or motion program.
No speed loop P/PI control switching
Speed loop P/PI control switching
