Description:
144
● FWAY/-FWAY: Use this setting.
– For a linear actuator with a carrier pin mounted on the ac‐
tuator spindle
– In conjunction with devices which use an internal potentiom‐
eter
● LWAY/-LWAY: Use this setting for an external linear potenti‐
ometer on a linear actuator (e.g. with cylinder drives).
● ncSt/-ncSt: Use this setting for a part-turn actuator for:
– An NCS sensor 6DR4004-. N.10 and -.N.40
– A positioner 6DR5...-0..9.-....- L1A with internal NCS module
– A positioner 6DR59* with accessory NCS module
6DR4004-5L/-5LE
– Position Transmitter 6DR4004-2ES, -3ES and -4ES
● ncSL/-ncSL: Use this setting for an NCS sensor 6DR4004-.N.20
on a linear actuator for strokes < 14 mm (0.55 inch).
● ncSLL/-ncLL: Use this setting for a linear actuator for:
– An NCS sensor 6DR4004-.N.30 for strokes > 14 mm
(0.55 inch).
– A positioner 6DR5...-0..9.-....- L1A with internal NCS module
– A positioner 6DR59* with accessory NCS module
6DR4004-5L/-5LE
– Position Transmitter 6DR4004-2ES, -3ES and -4ES
In the case of actuators with inverted direction of action, use the
settings with the minus sign, e.g. -turn.
Meaning of actuator with normal direction of action:
● Part-turn actuator closes when the drive shaft, positioner shaft
or magnet of the NCS sensor rotates in the clockwise direction.
● Linear actuator closes when the actuator spindle moves down‐
wards and the positioner shaft or magnet of the NCS sensor
rotates in the anti-clockwise direction.
Meaning for actuator with inverted direction of action:
● Part-turn actuator closes when the drive shaft, positioner shaft
or magnet of the NCS sensor rotates in the anti-clockwise di‐
rection.
● Linear actuator closes when the actuator spindle moves up‐
wards and the positioner shaft or magnet of the NCS sensor
rotates clockwise.
Additional information:
● The '3.YWAY' Range of stroke (Page 145) parameter is dis‐
played only for 'WAY', '-WAY', 'ncSLL' or '-ncLL'.
● turn/-turn: The '2.YAGL' Rated angle of rotation of feedback
(Page 145) parameter is automatically set to 90° and cannot be
changed.
