IV SPC-10 9902a

Designated use
The SPC-10 is designed for fitting into a machine or an
automated system.
In conjunction with a cylinder of type DGP(L)-..., the
potentiometer type MLO-POT-...-TFL and a proportional
directional control valve type MPYE-5-... , the SPC-10
can move at speed to one of two end positions set with
fixed stops. The end position cushioning is regulated
electronically. The cushioning path of the internal end
position cushioning of the cylinder (PPV) should not
project into the range of the working stroke.
The SPC-10 may only be used as follows:
– in accordance with designated use
– in its original state
– without any modifcations by the user
– in faultless technical condition.
When used together with commercially available com-
ponents, such as sensors and actuators, the specified
limits for pressures, temperatures, electrical data, tor-
ques etc. must be observed. National and local safety
regulations must also be observed.
Service
Please consult your local Festo repair service if you
have any technical problems.

trained in control and automation technology.
Important user instructions
This manual contains instructions on the possible
dangers which may occur if the SPC-10 is not used
correctly. These instructions are printed in italics, are
enclosed in a frame and also marked with a pictogram.

1.1 Structure
In conjunction with a cylinder of type DGP(L)-..., the
potentiometer type MLO-POT-...-TFL and a proportional
directional control valve type MPYE-5-... , the SPC-10
can move at speed to one of two end positions set with
fixed stops. The end position cushioning is regulated
electronically. The diagram below shows the principal
structure of a cylinder with the SPC-10.

1. Summary of system
SPC-10 9902a 1-3

With the SPC-10, movement from one fixed stop to the
other is closed-loop regulated. During commissioning,
the end positions (position of the fixed stops) are
”taught” by the SPC-10. During operation it then en-
sures that the slide moves at the highest possible
speed into the programmed end positions under closed-
loop control. Shortly before the slide reaches the end
position, it is braked so that it comes to a stop in the
end position.
In order that the slide remains in the end position, it is
pressed against the fixed stop, at maximum with a
pressure equal to the operating pressure.
Compared with pneumatic-impact drives with double-
solenoid control, this closed-loop procedure permits
higher positioning speeds. Also, the following measures,
which would be required for controlling a cylinder with a
single-solenoid valve, can be dispensed with:
Advantages
•the use of restrictors
•the use of limit switches
•the use of mechanical end position cushioning
(shock absorbers)
•the maintenance of fixed stops.
Compared with pneumatic-impact drives with double-
solenoid control, the SPC-10 permits:
•higher machine cycle times
•less vibration of the system
•lower maintenance costs.

You will require the following components for imple-
menting fast movement with electronically closed-loop
controlled end position cushioning:
Components
•the SPC-10
•a proportional directional control valve type
MPYE-5-...
•a service unit with 5 µm filter, without lubricator
•a potentiometer type MLO-POT-...-TLF
•a cylinder, if necessary with mechanical guide
•two fixed stops
•24 V DC power supply
•if necessary, components for a pneumatic emer-
gency stop circuit.

1.2 Method of operation
The SPC-10 is enclosed in an aluminium housing and
performs the following tasks:
Tasks of the
SPC-10 •it determines characteristic system values of the con-
nected components
•it saves the desired end positions
•it specifies the two end positions
•it compares the nominal and actual positions and
controls positioning by means of the proportional di-
rectional control valve (status control).
The SPC-10, the valve, the cylinder and the poten-
tiometer are connected to form a closed-loop control
circuit. The position of the slide or of the piston repre-
sents the control variable in this control circuit. This cir-
cuit is therefore also called a positioning control circuit.
Method of
operation
In the following section the terms piston and slide have
the same meaning.
The following diagram shows the principal structure of a
positioning control circuit with the SPC-10.

The potentiometer continuously registers the position of
the slide and passes this information on in the form of
an electrical signal to the SPC-10. The SPC-10 com-
pares the actual position with the programmed cylinder
end position and calculates therefrom the positioning
signal for the proportional directional control valve.
The proportional directional control valve controls the
slide by pressurizing one cylinder chamber and ex-
hausting the other. The flow is blocked in the valve
slide mid-position.
