● WAY/-WAY: The positioner compensates the non-linearity. The
non-linearity is caused by the transformation of the linear move‐
ment of the linear actuator into the rotary movement of the po‐
sitioner shaft. For correct compensation, follow the instructions
in section "Preparing linear actuators for commissioning
(Page 117)".
Factory setting: WAY
8.4.1.2 '2.YAGL' Rated angle of rotation of feedback
Condition: Transmission ratio selector and the value set in the '2.YAGL' pa‐
rameter match. Only then does the value shown on the display
match the actual position.
Possible settings: ● 33°
● 90°
Purpose: 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 current
setting of the actuator is then measured more accurately. The fol‐
lowing is applicable:
● 33°: Strokes ≤ 20 mm
● 90°: Strokes 25 mm to 35 mm
● 90°: Strokes > 40 mm to 130 mm
Use the mounting kit:
● 6DR4004-8V for strokes up to 35 mm
● 6DR4004-8L for strokes greater than 35 mm up to 130 mm
'2.YAGL' can only be adjusted if '1.YFCT' is set to 'WAY'/'-WAY' or
'FWAY'/'-FWAY'.
With all other settings of '1.YFCT', an angle of 90° is automatically
set for '2.YAGL'.
Factory setting: 33°

Condition: ● Positioner is mounted.
● Carrier pin is mounted on the lever in accordance with the ac‐
