1 User instructionsEnglish
The Soft Stop type SPC11-... is intended for fitting into a
machine or an automation system. In conjunction with
permitted drives and measuring systems, as well as with a
proportional directional control valve type MPYE-5-..., the
SPC11 permits fast movement into two end positions set
with fixed stops as well as into one or two mid-positions.
Note
This brief summary is intended only for users who are
familiar with the SPC11. Please observe the safety in
structions as well as the information on the permitted
combinations of valves, drives and measuring systems.
These can be found in the System manual for the SPC11
(type P.BE-SPC11-SYS-...) and in the associated “Drive-
specific supplement”.
Caution
Always switch on the operating voltage supply first and
then the compressed air supply.
Before carrying out installation and/or maintenance
work, switch off the following power supplies either
simultaneously or in the following sequence:
1. compressed air supply
2. operating voltage for the SPC11.

3 Fitting and pneumatic installation
Mount the SPC11 on a flat surface. Use at least 3 screws
(M4) to fasten it.
Compressed air / service unit
S5 to 7 bar, dry, non-lubricated, 5 μm filter cartridge.
SFor good positioning behaviour, the compressed air on
the MPYE-5-...: must not fluctuate more than ± 1 bar.
SSufficient standard flow (reference value: twice the
standard flow of the valve).
SUse a microfilter if slight oil mist cannot be avoided.
Proportional directional control valve (type MPYE-5-...)
SThis should be fitted and connected up symmetrically
to the centre of the drive. If fitted to moving parts, the
MPYE-5-... must be mounted at right angles to the
direction of movement.
SFit silencers with large rated flow (e.g. U-1/8), length
of tubing max. 1 m.
Compressed air tubing and screw connectors
SThe tubing for the valve drive must be symmetrical.
With linear drives: tubing length = drive length

Festo SPC11 2018-12b English6
SThe dimensions refer to the standard sizes of service
units, proportional directional control valves and
drives.
SIf angled connectors cannot be avoided, use plug
connectors from the Quick Star series.
SDo not use any restrictors in the supply lines.
Drive and measuring system
SUse only the permitted combinations of valves, drives
and measuring systems approved of by Festo for the
SPC11.
SObserve the permitted fitting positions.
SMount the measuring system symmetrical to the drive
stroke.
SMount the drive, the guide and the measuring system
free of play and flush in the direction of movement.
Specially for drives type DGP(I)(L)-...-...-KF or DGP-... with
suitable guide):
SWith bilateral air supply, open up completely the ad
justing screws for the internal end position cushioning.
SUse a measuring system with the same stroke length.

Festo SPC11 2018-12b English 7
Specially for measuring systems type MLO-POT-...-TLF:
SMount the measuring system so that it is electrically
isolated.
SIf the measuring system is to be used in a dusty or
dirty environment, mount it so that the actuator slide
faces downwards.
Specially for measuring systems type MLO-POT-...-LWG:
SIn order to earth the system, connect the earth/ground
cable on the flat plug of the measuring system to the
earth connection on the SPC11.
Specially for DNCI-...
SIn order to earth the earth connection of the SPC11
and the earth connection of the drive, connect them
with the same earth potential.
Fixed stops
SUse fixed stops to limit the working stroke. With drives
of type DGP(I)(L)-..., the working stroke should not
project into the range of the end position cushioning.
Mass load
SFasten the permitted mass load to the slide without
play.

Connections to the proportional directional control valve
When compressed air is applied to work connection 4,
movement is made in the direction of the zero point of the
measuring system. When compressed air is applied to
work connection 2, movement is made in the opposite
direction. With linear drives: the zero point of the measur
ing system lies on the side of the measuring system con
nection.

Connect an earth cable with sufficient cross-sectional area
to the drive if the drive is not fitted on an earthed machine
stand. Special earthing measures for components other
than those shown here can be found in the System manual
for the SPC11.
