13.7 Variables associated with coordinates
The values are given in the units set by general parameter INCHES.
If, INCHES = 0, in ten-thousandths of a millimeter (±999999999).
If INCHES = 1, in hundred-thousandths of an inch (±393700787).
If rotary axis, in ten-thousandths of a degree (±999999999).
Read-only variables
Accessing any of the variables POS(X-C), TPOS(X-C), APOS(X-C), ATPOS(X-C), DPOS(X-C),
FLWE(X-C), DEFLEX, DEFLEY or DEFLEZ interrupts block preparation and the CNC waits for that
command to be executed before resuming block preparation.
POS(X-C)
It returns the real tool base position value referred to machine reference zero (home).
On limit-less rotary axes, this variable takes into account the value of the active zero offset. The
values of the variable are between the active zero offset and ±360º (ORG* ± 360º).
If ORG* = 20º it displays between 20º and 380º / displays between -340º and 20º.
If ORG* = -60º it displays between -60º and 300º / displays between -420 and -60º
At the lathe model CNC, the coordinates of each axis are given as follows:
• When read from the CNC, they are given in radius or diameter, depending on the active units
system. Check the DIAM variable to know the active units system.
• When read from the PLC, they are always given in radius.
TPOS(X-C)
It returns the theoretical position value (real coor following error) of the tool base referred
to machine reference zero (home).
On limit-less rotary axes, this variable takes into account the value of the active zero offset. The
values of the variable are between the active zero offset and ±360º (ORG* ± 360º).

• When read from the CNC, they are given in radius or diameter, depending on the active units
system. Check the DIAM variable to know the active units system.
• When read from the PLC, they are always given in radius.
APOS(X-C)
It returns the real tool base position value, referred to part zero, of the selected axis.
At the lathe model CNC, the coordinates of each axis are given as follows:
• When read from the CNC, they are given in radius or diameter, depending on the active units
system. Check the DIAM variable to know the active units system.
• When read from the PLC, they are always given in radius.
ATPOS(X-C)
It returns the theoretical position value (real coor following error) of the tool base referred
to part zero.
At the lathe model CNC, the coordinates of each axis are given as follows:
• When read from the CNC, they are given in radius or diameter, depending on the active units
system. Check the DIAM variable to know the active units system.
