6.5 Single Direction Positioning Function
• General
For accurate positioning without play of the machine (backlash), final positioning from one direction is available.
When the positioning direction is minus
• Format
G60 P_;
P_: For an absolute command, the coordinates of an end position,
and for an incremental command, the distance the tool moves.
• Explanations
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
specified in the single direction positioning mode, the one-shot G command is effective like G codes in group 01.
