8.11 Spindle Origins P42<br />

Description<br />

Used to define the spindle origin positions.<br />

Principle<br />

8 - 24 en-938818/5<br />

Category Spindles<br />

Type 4 Unsigned decimal<br />

No. of words 4<br />

This <strong>parameter</strong> includes four decimal values defining the origin positions of spindles 1 to 4.<br />

Spindle 1 Word N0<br />

Spindle 2 Word N1<br />

Spindle 3 Word N2<br />

Spindle 4 Word N3<br />

The values are expressed in the internal measurement units (see 8.5).<br />

The spindle origin setting is effective on the first encoder marker pulse encountered during the first revolution:<br />

- if P42 = 0 —> Spindle measurement = 0 on first marker pulse,<br />

- if P42 = x —> Spindle measurement = x on first marker pulse.<br />

UNI-TE request (see UNI-TE Protocol User’s Manual)<br />

The spindle origins can be modified by a UNI-TE request. A reset (<strong>CN</strong>C reset) resets the <strong>CN</strong>C to the state specified<br />

by P42.
