1.YFCT - actuator type
You can use this parameter to adjust the positioner as per the respective actuator and, if
required, as per the position sensor used. The following parameter values are available:
● YFCT = turn
Use this parameter value for a part-turn actuator.
If you select "turn", the following parameter "2.YAGL" is automatically set to 90° and
cannot be changed.
● YFCT = WAY (factory setting)
Use this parameter value for a linear actuator. The positioner compensates the non-
linearity caused due to the transformation of the linear movement of the linear actuator
into the rotary movement of the feedback shaft. For this purpose, the positioner is set in
the factory such that it displays values between "P49.0" and "P51.0" when the lever on
the feedback shaft is perpendicular to the linear actuator spindle.
● YFCT = LWAY
Use this parameter value for:
– An external linear potentiometer on a linear actuator.
– An external linear potentiometer on a part-turn actuator with a reverse direction of
action.
● YFCT = ncSt
Use this parameter value when you use a non-contacting position sensor on a part-turn
actuator.
