Type of actuator as well as mounting type and direction of action
are known.
Actuator with normal direction
of action
• turn
• WAY
• LWAY
• ncSt
• ncSL
• ncSLL
Use this parameter to adjust the positioner to the respective actua-
tor.
• turn/-turn: Use this setting for a part-turn actuator with a directly
mounted positioner.
• WAY/-WAY: Use this setting for a linear actuator.
• LWAY/-LWAY: Use this setting for an external linear
potentiometer on a linear actuator.
• ncSt/-ncSt: Use this setting for an NCS sensor (6DR4004-.N.10
and -.N.40) on a part-time actuator.
• 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 an NCS sensor (6DR4004-
.N.30) on a linear actuator for strokes > 14 mm (0.55 inch).
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 NCS rotates in the clockwise direction.
• Linear actuator closes when the actuator spindle rotates
downwards and the positioner shaft or NCS rotates in an anti-
clockwise direction.
Actuator with inverted direction of
action
• -turn
• -WAY
• -WAY
• -ncSt
• -ncSL
• -ncLL
