Input Definitions
Input Description
Spare
Spare inputs are activated through the part program. If a Spare input is
located in the part, the control will pause the process until the input state
is detected. The Spare inputs may be used by use of specific EIA “W”
and “M” codes indicating the input number and function. Refer to
Appendix A in the operator’s manual for a complete description of these
commands.
Oxygen Cut Sense
Activation of this input confirms that Cut Oxygen is on and that motion
can begin after any selected preheat or pierce dwells are completed.
Note: The control requires a transition on this input before it will
command any motion along the cut path. If an Oxygen Cut Sense output
is not available on the machine, the control’s Oxygen Start output can be
wired back into the Oxygen Cut Sense input.
Program Inhibit
The Program Inhibit input will force the control to command the motion
output to a zero (0) speed. This is generally used as a dwell to pause
motion during a tool change or as a pause from a PLC interface.
Plasma Select
If the Plasma Select input is on, the control will apply Plasma cut logic
while cutting. If off, it will assume Oxy Fuel cutting is required and Oxy
Fuel cut logic is applied when cutting. This is generally activated by use
of an external switch to indicate Plasma mode.
Arc On Sense
Activation of this input indicates that the plasma arc has transferred to
the work piece. If the “Arc On Feedback” setup parameter is On, then
machine motion will begin at the activation of this input.
Drive Disabled
If the Drive Disabled input is activated, the control will stop all motion and
generate a fault message. Position information will be lost.
Remote Pause
A Remote Pause input, when activated, will stop all control motion and
display the Pause screen. No motion will be allowed until this input is
deactivated.
Limit Switch This input indicates that the machine has traveled into its full positive
travel of an axis. If the hardware overtravels are enabled and this input is
activated, the control will stop all motion and generate a fault message.
Motion will not be re-enabled until the switch is deactivated. (Type “M”
configuration only)
Remote Start When a Remote Start input is detected, it will begin the selected program
cycle as if the Start button on the control had been pressed.
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
