Signal list
Signals
Signal name Type Description
Plasma Start Input When active, the plasma system will fire an arc.
Machine Motion 1 Output Indicates the arc has transferred to the plate. This signal is selected
using jumper on power supply control board. Only 1 motion signal
is needed per system. The remaining motion signals can be used to
wire multiple systems in a daisy chain configuration.
Machine Motion 2 Output Indicates the arc has transferred to the plate. This signal is selected
using jumper on power supply control board. Only 1 motion signal
is needed per system. The remaining motion signals can be used to
wire multiple systems in a daisy chain configuration.
Machine Motion 3 Output Indicates the arc has transferred to the plate. This signal is selected
using jumper on power supply control board. Only 1 motion signal
is needed per system. The remaining motion signals can be used to
wire multiple systems in a daisy chain configuration.
Machine Motion 4 Output Indicates the arc has transferred to the plate. This signal is selected
using jumper on power supply control board. Only 1 motion signal
is needed per system. The remaining motion signals can be used to
wire multiple systems in a daisy chain configuration.
Hold Ignition Input When active, the system will stay in preflow and delay torch ignition.
The signal should be applied at the same time the start signal is
applied.
System Error Output Indicates that an error has occurred in the plasma system. Use the
serial interface to query for the specific error code number.
