Safety function for servopneumatics
Mechanical and pneumatic
stopping
Features
• Protection against unexpected
start-up (2-channel)
• Safety measure: stopping
(2-channel)
• Safety measure: blocking
(1-channel)
• Stop category: “1”
• Pressure supply not deactivated
Notes
• Recommended for vertical axes
• When the emergency stop is
activated, the compressed air
remains trapped in the drive;
the drive is not free of
compressed air.
• The braking unit, together with
the servopneumatic controller,
can prevent a movement on
restart.
• If only one clamping unit/cartridge
is used, the axis must be at a
standstill before it is clamped.
This standstill can be generated
via a STOP signal with the
servopneumatic controller.
The emergency stop valves VSVA
are then deactivated with a time
delay.

Description
Proportional valve, component of the servopneumatic
system as a first channel
5/2 single solenoid switching valve, with spring return and
auxiliary pilot air as a 2nd channel. The size (flow rate) is
based on the proportional valve.
3/2 single solenoid switching valve with spring return
Standard cylinder with clamping unit, displacement encoder
attached externally
Pressure switch for monitoring the emergency stop valves
