4 Main Spindle

The spindle is controlled by the PLC.
The spindle speed (S output) can be either an analogue voltage output or a coded output. The
spindle speed is programmed in rpm in the NC-program.
The machine parameter MP3010 determines whether the spindle speed is a coded output or an
analogue output, and whether the spindle orientation should be active.
Up to eight gear ranges can be defined by machine parameters.
Tapping cycles are available for tapping with and without floating tap holder.
MP3010 Spindle-speed output, Spindle orientation
Entry: 0 to 8
0 =No spindle-speed output
1 =Coded output of the spindle speed,
only if the spindle speed changes
2 =Coded output of the spindle-speed at every TOOL CALL
3 =Analogue output of the spindle speed and gear-change signal,
only when the gear range is changed
4 =Analogue output of the spindle speed and gear-change signal
at every TOOL CALL
5 =Analogue output of the spindle speed and no gear-change signal
6 =As for Entry value 3, but with controlled spindle for orientation
7 =As for Entry value 4, but with controlled spindle for orientation
8 =As for Entry value 5, but with controlled spindle for orientation
The functions are described in detail in the following sections.
