Description of parameters 1 through 5
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.
The subsequent 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 positioner 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 positioner 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 sensor on a part-turn actuator.
● YFCT = -ncSt
Use this parameter value when you use a non contacting sensor on a part-turn actuator
with a reverse direction of action.
● YFCT = ncSL
Use this parameter value when you use a non contacting sensor on a linear actuator.
● YFCT = ncSLL
Use this parameter value when you use a non contacting sensor on a linear actuator for
which the position is transformed by a lever into a rotary movement.
Note
The "3.YWAY" parameter is displayed only for "WAY" and "ncSLL".
The factory setting is "WAY".
