44 Installation & Setup Guide
X +Overtravel Switch
This input indicates that the machine has traveled into its full positive
travel in the X axis. If the hardware overtravels are enabled and this input
is activated, the control will stop all motion, generate a fault message
and only allow manual motion in the X axis negative direction.
X -Overtravel Switch
This input indicates that the machine has traveled into its full negative
travel in the X axis. If the hardware overtravels are enabled and this input
is activated, the control will stop all motion, generate a fault message
and only allow manual motion in the X axis positive direction.
Y +Overtravel Switch
This input indicates that the machine has traveled into its full positive
travel in the Y axis. If the hardware overtravels are enabled and this input
is activated, the control will stop all motion, generate a fault message
and only allow manual motion in the Y axis negative direction.
Y -Overtravel Switch
This input indicates that the machine has traveled into its full negative
travel in the Y axis. If the hardware overtravels are enabled and this input
is activated, the control will stop all motion, generate a fault message
and only allow manual motion in the Y axis positive direction.
Power Supply OK
This is an input used for the optional Automated Process Controller
(APC). It is used to confirm a ready condition from the Plasma Power
Supply before beginning the cut process.
Fast Stop
The Fast Stop input is used as an urgent stop input command to the
control. When the Fast Stop input becomes active, the control will
decelerate motion using a special Fast Stop Decel parameter, and forces
the operator to the Pause Screen. One second after the input becomes
active, the Drive Enable output from the control will turn off and disable
motion. Position information and I/O points will be maintained while the
input is active. This will allow the operator to recover the last position
after the input has been cleared. Note: The Fast Stop Decel parameter
is located on the password protected Speeds setup screen.
Torch Collision
The Torch collision input is used on torch systems with “break away”
style mounts. In the event that a torch should make contact with the
plate or any obstacle which causes the break away mount to release, an
input for the mount would be tied back to the control indicating a torch
collision has occurred. The operator will then be forced to the Pause
screen. While the input is active, the Cut output will be turned off and
manual motion will be enabled, allowing the operator to raise, lower and
move the torch position to clear the fault. Note: Position information,
motion command and I/O points are maintained, allowing the operator to
return to the cut path and resume cutting. This feature uses the Fast
Stop Deceleration rate. Manual raise inputs may be used.
Joystick ( Direction)
The Joystick directional inputs ( Up, Down, Left and Right) are used to
command manual motion when using and external joystick.
Fume Extraction Sense
If selected, the Fume Extraction input is used to confirm that a external
Fume Extraction system on the cutting table is operational prior to
beginning the cut. An option to override is displayed if the input has not
been satisfied at the time of the cut.
