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.

5 Start-up
Caution
In order to avoid damage caused by uncushioned
movement into the end positions, make sure in the
following cases that you observe the safety instructions
as well as the information on how to proceed in the
manuals for the SPC11.
‒ when first commissioning
‒ after adjusting the fixed stops
‒ after replacing components.
Instructions on commissioning the SPC11 as supplied from
the factory (without pre-parametrizing) can be found in the
System manual for the SPC11.
If the SPC11 is already pre-parametrized, carry out com
missioning as follows:
1. Before commissioning:
SSwitch off the compressed air and the power supply.
SApply a 0-signal to all P... inputs. start 0-signal
SMount the maximum permitted mass load and the
fixed stops.
2. Switch on the operating voltage supply.
3. Check the parameters shown after switching on.
4. Finally, switch on the compressed air supply. The valve
slide assumes the mid-position. The drive can move
slowly into one of the end positions.

Festo SPC11 2018-12b English 13
Caution
During commissioning and during operation the move
able mass is moved at the highest possible acceleration
and speed. Make sure that the complete positioning
range is free.
5. When the display “t..” flashes, hold the Enter/Teach
button down at least 2 seconds (Remote: input I6),
until the Teach procedure starts. During the teach pro
cedure, the SPC11 moves the drive automatically and
thereby ascertains the positions of the fixed stops, as
well as individual features of the drive, and carries out
reference travel if necessary (only for SPC11-INC).
When the teach procedure is completed, the drive
stands in end position 1 (display “P.01”).
6. If necessary, teach the mid-position. To do this move
the drive with the buttons {/– or +/}(Remote: I5,
I7) and transfer the position with Enter/Teach.
The positioning behaviour improves automatically after
approx. 20 to 30 strokes (adaption).
Caution
In order to avoid damage due to uncushioned move
ment into the end positions:
‒ Carry out commissioning again if the fixed stops have
been adjusted or if components have been replaced.
‒ Observe the maximum permitted mass load.

Festo SPC11 2018-12b English14
6 Instructions on operation
Note
For incremental path measuring systems: After switch
ing on the SPC11 again (POWER OFF/ON), the first
thing you have to do is trigger an order to move to the
end position P.01 or P.02, thus starting reference travel.
Other positioning tasks are not permitted and result in
the error E18 (reference travel).
Control the drive with the inputs P.01 to P.04 (see
section4). When the position is reached, a 1-signal will be
displayed at the relevant output. If a mid-position is
exceeded, the relevant output will supply a 1-signal for
50ms.
Change of direction is possible at any time during
positioning.
Optimizing the positioning behaviour (if necessary).
SCheck the system structure and the compressed air
reservoir when there are fluctuations in pressure or
when the supply pressure has been modified.
SAdapt the amplification or cushioning stage.
SIf necessary, fit restrictors in the exhaust tubing of the
MPYE-5-... in order to reduce speed.
