(6) Position proportioning control
Both valve opening signal (feedback resistance input) from the control motor and measured value
(PV) from the controlled object are fed back to perform control.

Neutral zone
The neutral zone is an area where the output between open-side and close-side outputs is turned off.
This zone is used to prevent the output signal from being frequently output to the control motor.
The output addition value within the neutral zone is temporarily held and when it is out of the neutral
zone, the output to the control motor starts.

Integrated output limiter
This function is used to integrate the open-side (or close-side) output when this output is continuously
output and to turn off the output when it reaches the integrated output limiting value preset. However,
if the output signal on the opposite side is output once, the integrated value is reset.
This value is set within the range from 100.0 to 200.0 % of motor driving time.
The opening output is not
turned on until the control
computation result (
MV)
becomes the neutral zone
value or more.
