e-6 HD4070 Instruction Manual
THC_MANUAL, THC_AUTO – put THC for current torch into manual or automatic mode
Comment – On power-up, the power supply puts the THC into AUTO mode.
After power-up, the THC mode changes only by operator command.
The THC does not automatically return to AUTO mode when a cut is started.
Response Data – THC configuration. Response is either THC_MANUAL or THC_AUTO.
THC_SLEW_UP, THC_SLEW_DOWN – start slew on active THC
Comment – Hardware protection exists and may terminate a slew command prematurely.
Response Data – THC configuration
THC_SLEW_STOP – stop THC slew
Response Data – THC configuration
THC_JOG_UP – move THC up (away from workpiece) a fixed increment
Response Data – THC configuration
THC_JOG_DOWN – move THC down (toward workpiece) a fixed increment
Comment – Hardware protection may void this command.
Response Data – THC configuration
READ_PLASMA_AMPS – get actual arc current
Response Data – arc current in amps. arc current is zero when the torch is not cutting
READ_PLASMA_VOLTS – get actual arc voltage
Response Data – arc voltage in tenths of volts
arc voltage is zero when the torch is not cutting
arc voltage is zero if there is no THC installed on the active torch
SET_CUTSPEED – set the RECOMMENDED cut speed, useful for customization
Command Data – new recommended cut speed in inches per minute
Response Data – recommended cut speed in inches per minute
GET_INLET_GAS_ n, (n=1,2,3) – get type and inlet pressure of specified gas
Response Data – (gas type) (gas pressure in psig) blank delimited
gas type is an enumeration from CNCdatadefs.h; it could be NO_GAS
gas pressure is the manifold supply pressure; it could be zero
GET_GAS_FLOW_XX_n, (XX=PreCut, CuT, PreShield, SHield), (n=1,2) – get gas flow-rate of specified gas
Response Data – gas flow-rate as a percent of full, e.g. “50” means half-flow
GET_GAS_TYPE_XX_n, (XX=PreCut, CuT, PreShield, SHield), (n=1,2) – get type (eg oxygen) of specified gas
Response Data – enumerated gas type
SET_GAS_FLOW_XX_n, (XX=PreCut, CuT, PreShield, SHield), (n=1,2) – set gas flow-rate of specified gas
Comment – receipt of this command will terminate any gas-flow tests in progress
Command Data – gas flow-rate as a percent of full, e.g. “50” means half-flow
Response Data – gas flow-rate as a percent of full, e.g. “50” means half-flow
SET_NOMINAL_AMPS – change arc current Set-point
Command Data – desired arc current Set-point
Response Data – actual arc current Set-point in amps
SET_ NOMINAL_VOLTS – change arc voltage
