1.2. In the case of a rotary axis B type whose movable range is over one rotation
As for an axis whose movable range is over one rotation and its rotary scale which
has no rotary data , for example, 30.000 degree and 390.000 degree have completely
same scale data though their position is different from each other by just one rotation.
It is possible to set rotary axis B type because CNC saves the rotary data by the
following parameter even if in this case.
#7 #6 #5 #4 #3 #2 #1 #0
1815 RVSx
[Data type] Bit axis
RVSx Specifies to save rotary data by CNC so that rotary axis B type is set for
the axis using scale without rotary data
0: not to save (as it is)
1: to save
NOTE
・ In the case of a rotary axis B type whose movable range is over one
rotation, a rotary scale with rotary data had better be used.
・ It is necessary to turn the CNC off after setting this parameter.
・ This parameter is available for only the rotary axis B type.
・ In case of moving over 180 degree during turning off, the coordinate
value may get out over a rotation because CNC saves rotary data just
before CNC turns off and in following turning on gets from the data.
・ Perform reference position establishment again when this parameter
was changed.
For No.1815#0(RVS) following CNC software is allowed.
