Features
• Protection against unexpected
start-up (2-channel)
• Safety measure: pressure
release (1-channel)
• Safety measure: stop
(1-channel)
• Stop category: “0”
(EN 60204-1)
• Pressure supply not
deactivated
Notes
• This set-up is only
recommended for horizontal
axes.
• The axis can still move after
an emergency stop. The
overtravel depends on the
current speed and the moving
mass.
• On reactivation, the drive
can move, depending on the
activation conditions.
• Use of a braking/clamping
unit, together with the
servopneumatic controller,
can prevent a movement
on restart.
