[Data type] Bit
MCN Machine position
0 : Not displayed according to the unit of input.
(Regardless of whether input is made in mm or inches, the machine
position is displayed in mm for millimeter machines, or in inches for
inch machines.)
1 : Displayed according to the unit of input.
(When input is made in mm, the machine position is displayed in mm,
and when input is made in inches, the machine position is displayed in
inches accordingly.)
PPD Relative position display when a coordinate system is set
0 : Not preset
1 : Preset
NOTE
When PPD is set to 1 and the absolute position display is
preset by one of the following, the relative position display is
also preset to the same value as the absolute position display:
1) The manual reference position return
2) Setting of a coordinate system by G92 (G50 for T series
G code system A)
DRL Relative position
0 : The actual position displayed takes into account tool length offset (M
series) or tool offset (T series).
1 : The programmed position displayed does not take into account tool
length offset (M series) or tool offset (T series).
NOTE
When tool geometry compensation of the T system is to be
performed by shifting the coordinate system (with bit 4 (LGT)
of parameter No.5002 set to 0), the programmed position,
ignoring tool offset, is displayed (with this parameter set to
1), but the programmed position, ignoring tool geometry
compensation, cannot be displayed.
DRC Relative position
0 : The actual position displayed takes into account cutter compensation
(M series) or tool nose radius compensation (T series).
1 : The programmed position displayed does not take into account cutter
compensation (M series) or tool nose radius compensation (T series).
DAL Absolute position
0 : The actual position displayed takes into account tool length offset (M
series) or tool offset (T series).
1 : The programmed position displayed does not take into account tool
length offset (M series) or tool offset (T series).
