PI/P control conversion function involves converting between PI control and P
control, based on the parameter conditions inside the servo (torque, speed,
acceleration, position difference).
Speed control: to inhibit overshoot / undershoot during acceleration/deceleration
Position control: to reduce position determination time by inhibiting undershoot
during determination action.
Similar effect can be achieved by acceleration/deceleration setting at the host
device, soft start setting of the servo drive, and position command filter, etc.
Figure 39. P/PI Control Conversion
You can set this function by P/PI control conversion mode (0x2114). Please see the
explanation below. Conversion to P control by PCON input is given priority over the
set value herein.
