For information on the machine's safety devices and
emergency stop chain see the manual provided by the
CNC machine's manufacturer. The manufacturer of the
CNC machine is responsible for the proper installation
of the emergency stop.
2.8.1 'CNC ready' signal - Emergency stop inter-
locking
DANGER!
Injuries due to uncontrolled operation!
An inactive 'CNC Ready' signal represents a safety
related situation. The "CNC Ready" relay is switched
off when the PA CNC control unit is in a situation
where the axes' movements are
not
controlled.
As the axes may continue to move in an uncontrolled
manner, the contacts of the "CNC Ready" relay must
be used to disconnect the machine's emergency stop
safety chain. All actions necessary for safety must be
executed in the same way as when the
Emergency Stop button is pushed.
n
Properly integrate the 'CNC ready' relay into the machine's
emergency stop chain.
All safety related actions must ensure that at least all axes
movements and spindle rotation (or beam power) are stopped as
quickly as possible.
n
Refer to the drive manufacturer manual, to determine the best
way of stopping movements and other dangerous power on the
machine.
n
If drive capability does not exist, the use of external braking
resistors might be necessary.
Unbalanced axes have to execute with the mechanical brake.
The contacts for 'CNC Ready' and 'Power OK' are available on
Chapter 5.4 “Wiring for machine safety”
).
