Operation at potentiometer input error
To adjust the PID constants, run AT.
When position proportional control is selected, "Closed/Floating", "Motor calibra-
tion", "Travel time", "Position proportional dead band", "Open/Close hysteresis",
"Operation at potentiometer input error", and "PV dead band" can be used.

Run "Motor calibration" when a potentiometer is connected for closed control or
floating control that monitors the amount of valve opening.
This will also automatically set the "Travel time", which is the amount of time from
when the valve is completely open to when the valve is completely closed.
When performing floating control without a potentiometer, it is necessary to man-
ually set the "Travel time". Set the travel time to the amount of time from when
the valve is completely open to when the valve is completely closed.
The valve output hold interval (the duration of ON/OFF switching of open output
and closed output) is set in "Position proportional dead band", and the hysteresis
is set in "Open/Close hysteresis".
The relation to valve opening is shown below.
When the present value is inside the PV dead band, this function is used to per-
form control for PV = SP and stop unnecessary output when the PV is close to
the SP.
Use this setting to select whether to stop control or switch to floating control and
continue when a potentiometer error occurs during closed control.
OFF
ON
Closed control
Control whereby a potentiometer is connected to feed back the amount of
opening of the valve.
Floating control
Control without feedback of the amount of opening of the valve. Control is
possible without connecting a potentiometer.
