Move the axes
Only those axes set by means of a.m.p. AXISTYPE (P0) for each axis as to be controlled by the
PLC can be mentioned.
The position values of these axes, which can be either linear or rotary, can be programmed in either
Cartesian or polar coordinates.
These coordinates can also be defined via parametric programming using any global arithmetic
parameters (P100 thru P299)
When using parametric programming, it is recommended to previously assign a value to the
corresponding global parameter by means of the instruction: CNCWR.
To govern axes managed by PLC, use the following marks associated with “Feed-hold” and “Transfer
Inhibit”:
Feedrate of the axes
The programming format for the axis feedrate (F5.5) depends on the function (G94 or G95) and on
the work units selected for this execution channel.
• If G94, in mm/min. or inches/min.
• If G95, in mm/rev or inches/rev.
It must be borne in mind that this feedrate depends on the actual spindle rpm which is in the main
execution channel.
If the moving axis is rotary, the CNC interprets that the programmed feedrate is in degrees/minute.
... = MOV 150 R1
Assigns the value of 150 to register R1.
... = CNCWR (R1, GUP200, M100)
Assigns the value of R1 to parameter P200, (P200=150).
... = CNCEX (G90 G1 U P200, M100)
Requests the CNC to execute the command: G90 G1 U150. The U axis will go to position
150.
