NOTE
After "LWAY, ncSt, --ncSt or ncSL, ncSLL" have been adjusted, both
the following parameters "2. YAGL" and "3. YWAY" will not be
displayed.
Rated angle of rotation of the feedback shaft
In rotary 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:
33° for strokes ≤ 20 mm
S
90° for strokes > 20 mm
S
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 2-1, page 24 and figure 2-2, page 25) must correspond to the
angle value selected under "2.YAGL".
Lever arm transmission
NOTE
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.
Selection of the lever arm range: serves to display the real stroke after
initialization.
This parameter is only relevant for linear actuator. 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.
