Motor Calibration A Position-proportional Model must be used.
The Motor Calibration parameter is used to calibrate the valve position and automatically set
the travel time from completely open to completely closed. You can then check the valve
opening with the Valve Opening Monitor parameter.
If you set the Motor Calibration parameter to ON, the valve will open completely and close
completely, and then the setting of the parameter will change to OFF when the measure-
ment has been completed. “ERR” will be displayed if any of the following errors occurs dur-
ing execution. If an error occurs, check the wiring and other factors and execute motor
calibration again.
• The potentiometer input value does not change or changes backward between
completely open and completely closed because the wiring is wrong.
• The value of the potentiometer input is incorrect because of a broken wire, noise, or other
factor.
* Do not change to any other parameter during calibration.

Travel Time A Position-proportional Model must be used.
• The Travel Time parameter is set to the time from when the valve is completely open until
it is completely closed.
• This parameter is set automatically when motor calibration is executed. There is normally
no need to change it manually.
• To use the results of automatic motor calibration calculations with another Digital
Controller, set the following parameters as a set: Travel Time, Valve Completely Closed
Position, Valve Completely Open Position, and Potentiometer Specification Setting.
However, these settings will depend on the equipment. When precise operation is
required, execute motor calibration separately for each piece of equipment.
