CNC Machine Interface Connections
Perform the following steps to properly interface the Spirit200a system
with a CNC cutting machine. See the system schematic for additional
information.
Plasma Start Input
•
The Spirit200a requires a contact closure between P8 pins 3 and 4 to
commence the cutting or marking sequence. The sequence is
terminated when the contacts are opened. The contacts should be
rated for 12VDC - 10mA.
Plasma Cut/Mark Input
•
The Spirit200a requires a contact closure between P8 pins 1 and 2 to
put the system in plasma marking mode. Opening the contacts puts
the system in cutting mode. The operating mode should be selected
prior to applying a start signal. The contacts should be rated for
12VDC - 10mA.
Arc Hold Input
•
The Spirit200a requires a contact closure between P8 pins 10 and 11
to inhibit arc starting even though a plasma start signal has been
applied to the unit. When the contacts are opened, the arc is initiated.
This feature is used to decrease cycle time by allowing pre-cut gas and
contact sequencing to occur simultaneously with initial torch height
positioning. The contacts should be rated for 12VDC - 10mA.
Motion Output
•
The Spirit200a provides a maintained contact closure output between
P8 pins 12 and 14 as long as an arc is maintained between the torch
and the workpiece. The motion contacts are rated for .6A - 125VAC /
.6A - 110VDC / 2A - 30VDC.
Remote On/Off Input
•
The Spirit200a requires a maintained contact closure between P8 pins
5 and 6 to energize the system from a remote location, provided that
the emergency stop button on the front panel is not activated. Opening
the contacts deenergizes the system. If the remote on/off feature is
not used, install a jumper between terminal block TB1 positions 7 and
8. The contacts should be rated for 24VAC – 115mA.
Power Supply Ready Output
•
The Spirit200a provides a maintained contact closure output between
P8 pins 7 and 8 when the system is ready to cut or mark. The contacts
are open during gas purge or when an error occurs. The contacts are
rated for .6A - 125VAC / .6A - 110VDC / 2A - 30VDC.
