Description of function
When the feedback resistance is provided
1. Adjusting valve position automatically
2. The valve position can be manually changed.
3. Force the controller to switch to no feedback resistance control mode when feedback resistance input breaks
4. High/Low limit of valve position can be set.
When the feedback resistance is not provided:
1. Control motor operation can be restricted by the parameter “OUTL”.
2. The UP/DOWN key is used to output opening or closing signal in manual mode
2.1 UP key(open-side)
：
While the UP key is being pressed, open-side output (OUT1) is output continuously.
Releasing the UP key turns off the output on the open-side to hold the opened state at that time.
2.2 DOWN key(close-side)
：
While the DOWN key is being pressed, close-side output (OUT2) is output continuously.
Releasing the DOWN key turns off the output on the closed-side to hold the opened state
at that time.
