Proportional directional control valves VPWP
Overview
Servo-pneumatic drive technology
Positioning and Soft Stop applica
tions as an integral component of the
valve terminal CPX – the modular
peripheral system for decentralised
automation tasks.
The modular design means that
valves, digital inputs and outputs,
positioning modules and end-position
controllers, as appropriate to the ap
plication, can be combined in almost
any way on the CPX terminal.
Advantages:
Pneumatics and electrics – control
and positioning on one platform
Innovative positioning technology –
piston rod drives, rodless drives,
rotary drives
Actuation via fieldbus
Remote maintenance, remote diag
nostics, web server, SMS and e-mail
alert are all possible via TCP/IP
Modules can be quickly exchanged
and expanded without altering the
wiring

Proportional directional control valves VPWP
Key features
Axis controllers CPX-CMAX Technical data è Internet: cpx-cmax
Free choice:
Position and force control, directly
actuated or selected from one
of 64 configurable position sets.
If you are looking for something
more:
the configurable function for switch
ing to the next set enables simple
functional sequences to be realised
in the axis controller CPX-CMAX.
Everything is recognisable:
the auto-identification function
identifies each station with its
device data on the controller
CPX-CMAX.
Also included:
The functional scope of the con
troller CPX-CMAX includes actuation
of a brake or clamping unit via the
proportional directional control
valve VPWP.
Up to 7 modules (max. 7 axes)
can be operated in parallel and
independently of each other.
Commissioning via FCT (Festo con
figuration software) or via fieldbus:
no programming, only
configuration.
Advantages:
Greater flexibility
OEM friendly – commissioning
also via fieldbus
Clear installation
and fast commissioning
Cost-effective
You program the system
in your PLC environment
End-position controllers CPX-CMPX Technical data è Internet: cpx-cmpx
Fast travel between the mechanical
end stops of the cylinder, stopping
gently and without impact in the
end position.
Fast commissioning via control
panel, fieldbus or handheld unit.
Improved control of downtime.
Actuation of a brake or clamping
unit via the proportional directional
control valve VPWP is an integral
component of the controller CMPX.
Depending on the fieldbus chosen,
up to 9 end-position controllers can
be actuated on the CPX terminal.
All system data can be read and
written via the fieldbus, including,
for example the mid positions.
Advantages:
Greater flexibility
OEM friendly – commissioning
also via fieldbus
Clear installation
and fast commissioning
Cost-effective
– Up to 30% faster cycle rates
– Significantly reduced system
vibration
Improved work ergonomics
thanks to significantly reduced
noise level
The extended diagnostics help
to reduce the service time
of the machine
Proportional directional control valve VPWP Technical data è 7
The 5/3-way proportional direc
tional control valve for applications
with Soft Stop and pneumatic
positioning.

and CPX-CMAX.
Advantages:
Clear installation
and fast commissioning
Reduction of system downtimes
thanks to the new diagnostic
options
With switching output for
actuating a brake/clamping unit
