2.8 Machine safety
For information regarding the safety connector's specification and
wiring examples see
Chapter 3.7 “Safety connector” on page 75
Chapter 5.5 “Wiring for machine safety” on page 102
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
Injuries due to uncontrolled operation!
An inactive 'CNC Ready' signal represents a safety related situa-
tion. 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 emer-
gency 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 pos-
sible.
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 resis-
tors might be necessary.
Unbalanced axes have to execute with the mechanical brake.
The contacts for 'CNC Ready' and 'Power OK' are available on con-
nector X19 (see
Chapter 5.5 “Wiring for machine safety”
).
