Configuring a CNC as two and a half axes
7.17.2 PLC Program
The PLC program must be modified as follows in order for the machine to work properly with a two-
and-a-half-axis configuration:
• Stop the machine when the Z axis gets in position and the X-Y axes are going to start moving.
• Disabled the X-Y axes when the axis to be moved is the Z axis.
• Distinguish between the execution status of programs, cycles, jog mode and tool inspection in
order to set the Z axis as a dro axis (display only) or not.
• The PLC mark "TOOLINSP"must always be active. Otherwise, when a STOP is generated with
the PLC, it goes directly into tool inspection mode.
The PLC program must contain a routine for the two-and-a-half-axis configuration and for the 3-axis
configuration. Switching from one to the other must be automatic depending on the value of
parameter CODISET.
