Plasma discrete I/o
All the required discrete interface signals between the control module and the plasma system are marked with asterisks
(*) in the following table. All other signals are optional for multiple torch operation, improved performance, or reduction in
cycle times.
This connector
has a blue ring
The inputs have two different modes that are selected using switches behind the calibration and setup door. The inputs
can be configured for dry contacts (no external voltage), or for positive-voltage sourced inputs. The following discrete
signals are used to connect the ArcGlide THC to the plasma system if the Hypernet interface is not used.
Notes: If the THC controller interface is configured with dry contacts, LED operation on the discrete plasma
interface is reversed and the LEDs will turn OFF when input is active.
If the plasma system uses the Hypernet Interface for communication with the ArcGlide, these discrete
signals are not used. If discrete signals are used, the required signals of this connector must be
connected.
Plasma I/o Description
RS422
This is an optional signal path that provides the serial interface to the HPR power supplies. If
connected to an HPR auto gas system then all plasma related parameters can be set using this
interface. For both HPR auto and manual systems this interface can be used to get information on
the plasma system status and errors.
Note: The ArcGlide THC does not support the HPR serial protocol. It only relays the data
sent from the CNC through the Hypernet interface to the plasma system. Any data
received from the plasma system over the RS422 serial is then relayed to the CNC
through the Hypernet interface. It is the responsibility of both the connected CNC
and HPR plasma to fully support the serial protocol used.
Arc Transfer*
This is a required input to the ArcGlide. This signal is input to the ArcGlide from the plasma
system to indicate that arc transfer has occurred.
Plasma Error
This is an optional signal that is output from the plasma system to indicate that an error has
occurred.
Rampdown Error
This is an optional output from the plasma system that indicates the plasma torch lost arc
transfer before the controlled arc turn off. This condition indicates that the consumable life may
be reduced. The user is encouraged to make any changes to the part programming to reduce or
eliminate these types of errors to achieve optimal consumable life.
