Any mounting position is permitted (horizontal, vertical or
diagonal)
· Note that in conjunction with the SPC200, the complete
stroke of the drive must not be used.
Permitted work stroke = stroke length minus stroke
reduction
On each side of the drive positioning must not take place in
the range of the stroke reduction (see also chapter 3.4).
The best possible positioning
behaviour can be
achieved if you use only 80 % of the stroke length of
the drive, symmetrically to the two end positions.
If demands placed on the positioning behaviour are
o
nly slight, observe at least the following stroke re
ductions in both end positions:
Piston j [mm]
32 50
Stroke reduction per end position [mm] 10 15
· Drives with adjustable end position cushioning (PPV): In
order to use the end position cushioning as minimum
stop protection, tighten completely the adjusting screws
for the internal end position cushioning.
· Recommendation: Limit the positioning range by shock
absorbers, also in the case of a cylinder with adjustable
cushioning. In this way you can avoid damage in th
e
event of operating and system faults.
· Arrange the tubing between the valve (MPYE−5−...) and the
drive (DNCM−...) symmetrically and as short as possible.
Maximum tubing length = cylinder stroke length + 50 mm.
