G60 IP_;
IP_: Coordinates of an end point for tool movement when an
absolute command is specified
Parameter No. 5440 is used to set an overrun distance and positioning
direction. The tool stops once before a specified end point also when a
specified positioning direction matches the positioning direction set in
the parameter.
By setting bit 0 (MDL) of parameter No. 5431 to 1, the one–shot G code
G60 can be used as a modal G code of group 01. This eliminates the need
to specify G60 for each block, and enables one–shot G code to be
specified in the single direction positioning mode. The other
specifications are the same as for the one–shot G code G60.
