G91 Relative dimension specification
ć permitted in operating modes: Start/Stop, Record Select
Nn G91 X<Position> [Y.., Z.., U..]
<Position> n Position in [mm] or [°] n = ±9999.99
@n Position in [mm] or [°] saved in the position register @n n = 0 ... 99
Effect Switches to relative positioning and moves relatively at the current speed and, if
applicable, with ramp to the specified position. All the subsequent positions in the
program will be interpreted as relative dimensions. The positioning mode remains
valid until a new positioning mode is set (see also under G00/G01/G02).
Example N000 G00 G91 X200
N001 X100
N002 G90 X@5 Y@1
N003 G91 X–100
N004 X200
;Move relatively at highest possible
;speed 200 mm further
;Move relatively at highest possible
;speed 100 mm further
;Move to position from register 5 and register 1
;Move 100 mm in a negative direction
;Move 200mm in a positive direction
Remark The following is set during positioning:
Ĉ absolute positioning (G90)
Command G91 has a saving effect. It remains effective until it is cancelled by
command G90.
Example:
N010 G91 X100
N011 X200
N012 G90 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:
N013 G91 X@ABHOL_POS
N014 X@ABLAGE_POS
