Powermax65/85/105 SYNC Reference Guide 810400 29
0x3082 (gas pressure setting)
Example request and response
In this example, you want to put the Powermax65/85/105 SYNC into remote control mode and cut
at 63 A, with gas pressure set automatically by the plasma power supply.
Request from CNC:
:0110308000030600010FC0000066<CR><LF>
Description: Sets the gas pressure in psi.
To have the plasma power supply set the gas pressure automatically: Write a
value of zero (0x0000) to address 0x3082. The plasma power supply will automatically
set the gas pressure for optimum cutting related to the operating mode, the torch type,
the cartridge type, and the length of the torch lead.
To specify the gas pressure (psi) that you want: Multiply the gas pressure (psi) that
you want by 128, and convert the product to its hexadecimal value.
For example, to set the gas pressure to 45 psi: 45 X 128 = 5760 = 0x1680
Encoding or scaling: 16-bit, fixed-point binary with 1-bit sign at MSB and 7-bit decimal at LSB
Unit: psi
Function (hex): 10 (Write Multiple Registers) (recommended)
Also supported:
06 (Write Single Register)
Value Description
: Start of message
