@n

Position in [mm] or [°] saved in the position register @n

n = 0 ... 99

Effect

Switches to absolute positioning and moves absolutely at the current speed and, if
applicable, with ramp to the specified position. All the subsequent positions in the
program will be interpreted as absolute dimensions. The positioning mode remains
valid until a new positioning mode is set (see also under G00/G01/G02).

Example

N000 G00 G90 X200

N001 X100

N002 X@5 Y@1

N003 G90 Y100

N004 G91 X100

;speed to position X100
;Move to position from register 5 and register 1
;Move absolutely to position Y100
;Move 100 mm in a positive direction

Remark

The following is set during positioning:
Ĉ absolute positioning (G90)
Command G90 has a saving effect. It remains effective until it is cancelled by
command G91.
Example:

N010 G90 X100

N011 X200

N012 G91 X300

With WinPISA programming, positions can also be specified symbolically. For this
purpose, the position values and position names are entered in the position list.
Example:

N010 G90 X@ABHOL_POS

N011 X@ABLAGE_POS
