● YFCT = LWAY
● YFCT = ncSt
● YFCT = -ncSt
● YFCT = ncSL
● YFCT = ncSLL
The factory setting is "WAY".
2.YAGL - angle of rotation of the feedback shaft
Use this parameter for a linear actuator. For a linear actuator, set an angle of 33° or 90°
depending on the range of stroke. The following is applicable:
● 33° for strokes ≤ 20 mm
● 90° for strokes > 20 mm
Both angles are possible when using a lever up to a stroke of 35 mm.
The long lever with a stroke greater than 35 mm is intended only for an angle of 90°. The
long lever is not a part of the mounting kit 6DR4004-8V, but must be ordered separately
under the order number 6DR4004-8L.
The "YFCT = turn" parameter value sets an angle of 90° automatically in case of part-turn
actuators.
Note
Matching the angles
Ensure that the values set in the transmission ratio selector and the "2.YAGL" parameter
match. If not, the value shown on the digital display does not match the actual position.

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.
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.
Use this parameter value when you use a non-contacting position sensor on a part-turn
actuator.
Use this parameter value when you use a non-contacting position sensor on a part-turn
actuator with a reverse direction of action.
Use this parameter value when you use a non-contacting position sensor on a linear
actuator.
Use this parameter value when you use a non-contacting position sensor on a linear
actuator for which the position is transformed into a rotary movement using a lever.
Note
The "3.YWAY" parameter is displayed only for "WAY" and "ncSLL".
