S YFCT = ncSLL
This must be adjusted if an NCS is to be connected to a linear ac-
tuator with the position converted by an arm into a part--turn move-
ment.
.
NOTE
After “LWAY, ncSt, --ncSt or ncSL” have been adjusted, the parameter
“3. YWAY” will not be displayed.
Rated angle of rotation of the feedback shaft
In part-turn actuators, an angle of 90° is preset automatically by
1.YFCT = turn (see above). In linear actuators (1.YFCT = WAY) a
value of 33° or 90° can be selected depending on the stroke range:
S 33° for strokes ≤ 20 mm
S 90° for strokes > 20 mm
When using the lever up to 35 mm, both angles of rotation (33° and
90°) are possible.
The long lever (> 35 mm stroke) is only designed for an angle of
rotation setting of 90°. It is not part of the mounting kit set 6DR4004-8V
but must be ordered separately under order number 6DR4004-8L.
.
NOTE
The setting of the transmission ratio selector on the positioner (see
figure 2-2, page 17 and figure 2-3, page 18) must correspond to the
angle value selected under “2.YAGL”.
Lever arm transmission
Selection of the lever arm range: serves to display the real stroke after
initialization. The use of this parameter is optional. You only need to set
this parameter if you want to have the way in mm displayed at the end
of the initialization.
If the parameter value “oFF” is selected here, the real stroke is not
displayed after initialization.
.
NOTE
The specification “YWAY” must match the mechanical lever arm trans-
mission. The carrier must be set to the value of the actuator stroke,
if this is not scaled to the next highest scaled value.
