Siemens SIPART PS2 User Manual

● 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
– External position detection systems 6DR4004-2ES, -3ES
and -4ES
– An internal NCS module. No limitations apply to the internal
NCS module.
In the case of actuators with inverted direction of action, use the
settings with the minus sign, e.g. -turn.
Description: 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
downwards 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
direction.
● Linear actuator closes when the actuator spindle moves
downwards and the positioner shaft or magnet of the NCS
sensor rotates clockwise.
Additional information:
● The '3.YWAY' Range of stroke (Page 144) parameter is
displayed only for 'WAY', '-WAY', 'ncSLL' or '-ncLL'.
● turn/-turn: The '2.YAGL' Rated angle of rotation of feedback
(Page 143) parameter is automatically set to 90° and cannot be
changed.
● WAY/-WAY: The positioner compensates the non-linearity. The
non-linearity is caused by the transformation of the linear
movement of the linear actuator into the rotary movement of the
positioner shaft. For correct compensation see section
"Preparing linear actuators for commissioning (Page 118)".
Factory setting: WAY
8.3.1.2 '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°
