Operating Commands
The ArcGlide provides both Manual and Automatic modes of operation. For Manual mode operation, the ArcGlide HMI or
an operator console on the CNC is required.
Manual mode: The ArcGlide HMI or an operator console on the CNC controls the ArcGlide motion. To enter manual
mode, use the Remote Mode command (RM) set to 0 and the Height Control command (AA) set to 0.
Automatic Voltage Control (AVC): In AVC, also called Auto mode, the CNC controls the ArcGlide motion. To enable
Automatic Voltage Control, use the Remote Mode command (RM) set to 1 and Height Control command (AA) set to 1.
The Set Arc Voltage command (VS) provides the voltage setpoint for Automatic Voltage Control.
Sample Voltage: When Set Arc Voltage is set to 0, sample arc voltage control is enabled. After piercing, the ArcGlide
reads the arc voltage and uses the reading as the arc voltage setting. By sampling the arc voltage, the ArcGlide can
automatically compensate for consumable wear or torch lead length.
Voltage control off (AVC disabled): A discrete signal that is part of Auto mode, AVC disabled causes the ArcGlide to
position at the cut height and remain at that height regardless of the arc voltage.
See Operation on page 127 for more information.
Use the commands in the following tables to change ArcGlide settings for operational mode, cut settings, and error
recovery.
Height Control
Command ID Data Examples
AA 0 = Manual
1 = Automatic Voltage Control
>AA1B3< Automatic Voltage Control.
>AA0B2< Manual mode.
>AA?C1< Query from the CNC.
Selects operating mode for the ArcGlide: Automatic or Manual. You will also need to use the Set Arc Voltage command
(VS) to set the voltage for Automatic Voltage Control, or to select Sample Voltage (VS = 0 for sampled arc voltage).
Default: Previous setting
Remote Mode
Command ID Data Examples
RM 0 = OFF
1 = ON
>RM1D0< Turns on Remote mode, serial communication
only. The ArcGlide HMI is display-only.
>RM0CF< Turns off Remote mode. Parameter entry is
through the ArcGlide HMI only.
>RM?DE< Query from the CNC.
Set to On to allow serial communication with the ArcGlide. Set to Off to allow parameter entry from the ArcGlide HMI.
Default: OFF
