Address Meaning
AP Polar angle
AR Aperture angle for circular
interpolation
CALL Indirect cycle call
CR Radius for circular
interpolation
DC Absolute coordinate;
approach position directly
(for rotary axis, spindle)
DEF Definition instruction
GOTOB GoBack instruction
GOTOF GoTo instruction
IC Coordinate specified
using incremental
dimensions
IF Jump condition
$A_DBB[n] Data byte
$A_DBW[n] Data word
$A_DBD[n] Data double-word
$A_DBR[n] Real data
$A_MONIFA Factor for tool life
CT monitoring
Value assignments
0 ... 359.99999
Specification in degrees, traversing in polar
coordinates, definition of the pole; in addition: Polar
radius RP
0.00001 ... 359.99999 Specified in degrees; one possibility of defining the
circle when using G2/G3
– Special form of the cycle call; no parameter transfer;
the name of the cycle is stored in a variable;
only intended for cycle-internal use
0.010 ... 99 999.999 One possibility of defining a circle when using G2/G3
Negative sign – for
selecting the circle:
greater than semi-circle
– It is also possible to specify the dimensions for the end
point of a rotary axis with DC(...) irrespective of
G90/G91.
Defining a user variable of the type
BOOL, CHAR, INT, REAL, STRING[n],
to be defined directly at the beginning of the program
– A GoTo operation is performed to a block marked by a
label; the jump destination is in the direction of the
program start.
– A GoTo operation is performed to a block marked by a
label; the jump destination is in the direction of the end
of the program.
– The dimension can be specified for the end or center
point of a certain axis irrespective of G90.
– If the jump condition is fulfilled, the jump to the block
with Label: is performed; otherwise, next
instruction/block;
several IF instructions per block are possible
Comparison operators:
= = Greater than,
> greater than,
>= greater than or equal to
