4. INTERPOLATION FUNCTIONS
For accurate positioning without play of the machine (backlash), final
positioning from one direction is available.
_ : For an absolute command, the coordinates of an end
position, and for an incremental commnad, the distance
the nozzle moves.
An overrun and a positioning direction are set by the parameter (No.
5440). Even when a commanded positioning direction coincides with
that set by the parameter, the tool stops once before the end point.
G60, which is an one–shot G–code, can be used as a modal G–code in
group 01 by setting 1 to the parameter (No. 5431 bit 0 MDL).
This setting can eliminate specifying a G60 command for every block.
Other specifications are the same as those for an one–shot G60 command.
When an one–shot G code is sepcified in the single direction positioning
mode, the one–shot G command is effective like G codes in group 01.
G60 commands are used.
G60 command is used.
positioning mode start
D No single direction positioning is effected in an axis for which no
overrun has been set by the parameter.
D When the move distance 0 is commanded, the single direction
positioning is not performed.
D The direction set to the parameter is not effected by mirror image.
