26 Operator’s Manual
Kerf
Specifies the amount of kerf (cutter compensation) that will be applied to the current part program.
Care should be taken when selecting a kerf value as this parameter can cause invalid geometries to
be generated. For example, adding a kerf of 0.5” to an arc with a radius of 0.25”. After entering a
kerf value, the kerf compensated cut path can be viewed by pressing the Kerf softkey under the Part
Options menu.
Dwell Time
Specifies the amount of dwell (delay) to be inserted into the current part program when an
appropriate RS-274D program block is reached. This time can be overridden in the part program.
For example in EIA programming a G04 X3 will cause a three second dwell to be inserted at the
current program block. A G04 with no X-code will insert a dwell with the current Dwell Time
parameter.
Arc Radial Error
Specifies the arc error tolerance to be used when checking the current segment for dimensional
accuracy. All ESSI or EIA programs are comprised of lines, arcs, and circles. Arc Radial Error is
used to make sure that the starting and ending radial vectors are within tolerance to describe a valid
geometry.
Dwell Override
When this parameter is enabled, embedded dwell G04 Xvalue codes in an RS-274D program will
override the operator entered dwell time.
Optional Program Stop
Allows overriding of the optional program stop code M01 in the current part program. If enabled, an
M01 code operates identically to M00. If disabled, the M01 code is ignored.
EIA I & J Codes
Selects Absolute or Incremental RS-274D programming mode. In Incremental mode, all offsets for X,
Y, I and J relative to the current block. In absolute, mode all X, Y, I and J are relative to an absolute
reference point unless changed by using a G92 program code.
EIA F-Code Override
When this parameter is enabled, embedded F-codes in an RS-274D program will override any
operator entered Cut Speed.
Speed +/- Affects F-Codes
When this parameter is enabled, the control will apply the speed increase/decrease percentage to all
embedded F-codes encountered in the part program
EIA Decimal Shift
Some programming styles are structured so that the decimal point in the EIA positioning affecting part
sizing is assumed. The EIA decimal shift parameter allows the operator to select the location of the
decimal point when translating parts by selecting normal or single for correct translation. The
selection should be set to Normal unless your part programs have only a single digit to the right of the
decimal point.
Process Select Override
When enabled, this feature will allow the part program to override the process select input.
Station Select Override
When enabled, this feature will allow the part program to override the currently selected station select
input.
