TNC 360 4 Spindle 4-79
4 Spindle
The spindle is controlled by the PLC.
The spindle speed (S output) can be either an analog voltage output or a BCD-coded output. The
spindle speed is programmed in rpm in the NC program.
The machine parameter MP3010 determines whether the spindle speed is a BCD-coded output or
an analog 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
Input value: 0 to 8
0 =No spindle-speed output
1 =BCD-coded output of the spindle speed,
only if the spindle speed changes
2 =BCD-coded output of the spindle speed at every TOOL CALL
3 =Analog output of the spindle speed and gear-change signal,
only when the gear range is changed
4 =Analog output of the spindle speed and gear-change signal
at every TOOL CALL
5 =Analog output of the spindle speed and no gear-change signal
6 =As for Input value 3, but with controlled spindle for orientation
7 =As for Input value 4, but with controlled spindle for orientation
8 =As for Input value 5, but with controlled spindle for orientation
The functions are described in detail in the following sections.
