3.6 Controlled axes
Machine parameter MP50 determines which of the four NC-axes should be controlled.
MP50 Controlled axes
Entry value: 0 to 31
Bit 0 X axis +0 = not controlled
+1 = controlled
Bit 1 Y axis +0 = not controlled
+2 = controlled
Bit 2 Z axis +0 = not controlled
+4 = controlled
Bit 3 Axis 4 +0 = not controlled
+8 = controlled
Bit 4 * Axis 5 +0 = not controlled
+16 = controlled
Further parameters for the NC-axes may be found in the section "machine axes."
The PLC functions which are described in the following sections are only effective for controlled
axes.
3.6.1 Axes as programmable position displays
Machine parameter MP60 defines individual axes as programmable position displays (POSITIP
function).
For example: If MP60 = 3, the X and Y axes are considered to be programmable position displays
and only Z and 4th axes would be in closed loop control. X- and Y-axis positioning can still appear in
the NC program but the axes must be moved manually before the program can continue.
