4.3.4 Machine control panel (MCP) layout
The machine control panel in the standard version has been configured for simple turning ma-
chines (2 axes and one spindle).
The user can use the keys 1 – 6 and the associated LEDs (the same applies to keys 1 ... 6)
for his own purposes.
The keys 16–24 should be used as axis keys (see sample program SAMPLE). The program-
mer can assign the axis keys depending on his particular machine type.
