8.8 Spindle 2 Speed Ranges P47<br />

Description<br />

8 - 18 en-938818/6<br />

Category Spindles<br />

Type 5 Unsigned decimal<br />

No. of words 18<br />

Used to define the speed ranges for spindle 2 as well as the limit speed for each range.<br />

Principle<br />

This <strong>parameter</strong> includes six pairs of words defining the min and max speeds of ranges M40 to M45 and six words<br />

(N12-N17) giving the limit speed for each range.<br />

The automatic range search is not enabled unless P7, word 0, bit 7 equals 0.<br />

If the spindle speed programming format declared in P6 is S32, the speeds are expressed in hundredths of a revolution<br />

per minute.<br />

The limit speed must be less than or equal to the maximum speed for the range. If the value is zero (default value),<br />

the maximum speed of the range is considered as limit speed.<br />

If a programmed spindle speed is above the limit speed but below the maximum speed of the range and the range is<br />

programmed, it is refused with error 29. If the range is not programmed, a search for a range compatible with the speed<br />

is made (provided automatic range search is enabled: P7, word 0, bit 7 = 0).<br />
