11-16. ON-OFF servo type open loop method
(Code: open loop)
11-16-1. Outline of function
ON-OFF servo type open loop method performs time control based on switching time from fully close (chose) to
fully open (open) of the actuator without feedback resistance of the actuator (control motor etc.).
In case of ON-OFF servo type open loop method, instrument and the actuator need adjustment. Basically,
adjustment is performed automatically. Adjustment by annual is possible, however when use it first time, after
adjustment by automatic, then adjustment by manual.

[This instrument] [The actuator (control motor)]
On the above figure, this instrument and the actuator connect directly, but buffer relay need to put and connect
at actual connection.
Connect contact protective element to control relay output terminal.
Contact protective element which is pertained this instrument is for motor (for more than load current 700mA)
Use the contact protective element for light load for connecting buffer relay. When use pertained contact protective
element, movement is defected for leaking current.
11-16-3. Setting
Setting of ON-OFF servo type open loop method is performed by related to output of Mode 4.
Setting screen Description of the screen
1. Motor tuning
①
This screen is displayed when output type is ON-OFF servo type open
loop method.
②
This is the function which calculates setting value of motor fully open
and close time between this instrument and the actuator.
③
When start motor tuning, display AT progress status (START, OPEN,
CLOSE).
④
When stop the motor tuning in the middle, set the ‘END’.
⑤
Motor fully close and open time which is calculated by motor tuning is
confirmed by ’Motor fully close and open time’ of mode 4.
