Siemens SIPART PS2 series User Manual

B.2.4.2 Initialization of part-turn actuators
Procedure
1. For part-turn actuators operating in standard control direction, set parameter "1.YFCT" to
"ncSt", or to "-ncSt" in case of inverse control direction.
2. Launch initialization as usual with "INITA".
B.2.4.3 Initializing linear actuators with a stroke range up to 14 mm (0.55 inch)
Requirements
1. Set the "1.YFCT" parameter of the positioner to "ncSL" or - with inverse control direction -
to "-ncSL".
2. Launch initialization as usual with "INITA".
B.2.4.4 Initializing linear actuators with a stroke range > 14 mm (0.55 inch)
Note
Parameter values "ncSLL" and "-ncLL" are only available for devices of the 6DR5... series and
only with the firmware version > C4. Set the value to 90° on devices of the 6DR5... series with
firmware version < C5 (YAGL). This setting is also necessary for devices of the 6DR4... series.
Resultant non-linearity can be corrected by means of the programmable characteristic by
setting the parameter value from "SFCT" to "FrEE" and adapting the interpolation points.
Requirements
1. Set the "1.YFCT" parameter of the positioner to "ncSLL" or - with inverse control direction
- to "-ncLL".
2. Launch initialization as usual with "INITA".
