Influence of the Acceleration on the Speed Buildup Diagram<br />

Servo-Control<br />

REMARK When words 48, 50, 52 and 54 are equal to 0 and these words are the spindle<br />

accelerations, the spindles are started and stopped instantaneously without<br />

managing the accelerations. The same is true when programme <strong>parameter</strong><br />

E9033b is set to 0.<br />

The spindles on which the acceleration is set to zero must not be declared for<br />

indexing with constant acceleration (<strong>parameter</strong> P6, words 1 to 4, bit 5 equal to<br />

0).<br />

Programme Parameter<br />

Programme <strong>parameter</strong> E971xx is used to read the acceleration at the work rate.<br />

Programme <strong>parameter</strong> E972xx is used to read the acceleration at fast speed.<br />

Programme <strong>parameter</strong> E9033b (b from 0 to 3) is used to read the indexed spindle acceleration expressed in revolutions<br />

per deg/s2 .<br />

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

The axis accelerations 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 P32.<br />
