HD4070 Instruction Manual e-7
Command Data – desired arc voltage
Response Data – achieved arc voltage in tenths of volts
if no THC installed, arc voltage will always be zero
SET_THC_PARAMS – set all THC parameters. Not while cutting.
Command Data – THC parameters as blank-delimited integers
pierce height factor, percent
pierce delay, tenths of seconds
IHS speed, 1 to 10 (arbitrary scale)
IHS stall force, 1 to 10 (arbitrary scale)
retract speed, 1 to 10 (arbitrary scale)
retract height, thousandths of an inch
nozzle contact, 0=off, 1=on
cut height, thousandths of an inch
autokerf, 0=off, 1=on
machine accel delay, thousandths of a second (0-9000 = 0 to 9.000 seconds)
Response Data – THC configuration
GET_THC_PARAMS – get all THC parameters
Response Data – THC parameters actually set, in SET_THC_PARAMS format
a pierce height (the first parameter) of zero indicates that the parameter list is invalid
THC_IHS_TEST_START – initiate a test of the IHS setting: THC moves toward workpiece until contact is sensed
Response Data – (none)
THC_IHS_TEST_STOP – stop the test
Response Data – (none)
GAS_CUTFLOW_TEST_START – initiate a test of the cutflow gasses
Response Data – (none)
GAS_CUTFLOW_TEST_ STOP – stop the test
Response Data – (none)
GAS_PREFLOW_TEST_START – initiate a test of the preflow gasses
Response Data – (none)
GAS_PREFLOW_TEST_ STOP – stop the test
Response Data – (none)
Plasma System Responses
BAD_CHECKSUM – checksum received doesn’t match computed checksum
Response Data – (none)
BAD_COMMAND – unknown or illegal command
Response Data – (none)
CUTTING – PS is cutting and will ignore the command from CNC
Response Data – (none)
LOCAL_MODE – PS is in local mode, will not process commands from CNC
Response Data – (none)
