7.6 M41-M44. Gear change.<br />
Each spindle may have up to 4 different ranges (gears). Each gear means a speed range<br />
for the CNC work in. The programmed speed must be within the active gear; otherwise, a<br />
gear change will be required.<br />
The gear change may be automatic or <strong>man</strong>ual. When the change is <strong>man</strong>ual, the gear is<br />
selected with auxiliary functions M41 (gear 1) through M44 (gear 4). When the change is<br />
automatic, the CNC itself generates these functions according to the programmed speed.<br />
M41<br />
The graphic shows a spindle with three speed ranges (gears). The first gear goes from 0 to S1 rpm;<br />
the second one from S1 to S2; the third one from S2 to S3.<br />
The configuration of the speed ranges or gears (automatic or <strong>man</strong>ual change, maximum<br />
speed for each gear, etc.) is defined by the machine <strong>man</strong>ufacturer. See "How to know the<br />
gear configuration of a spindle." on page 128.<br />
Manual gear change.<br />
When the change is <strong>man</strong>ual, the gear is selected with auxiliary functions M41 through M44.<br />
Function. Meaning.<br />
M41 Selects gear ·1·.<br />
M42 Selects gear ·2·.<br />
M43 Selects gear ·3·.<br />
M44 Selects gear ·4·.<br />
These functions may be defined together with the programmed spindles or in a separate<br />
block. If several spindles are programmed in a single block, functions M41 to M44 apply to<br />
all of them. If the functions are programmed in a block that does not mention any spindle,<br />
the functions will only be applied to the master spindle of the channel.<br />
