POINT

In the continuous path control, a speed variation will not occur using the near-pass function when the positioning data No. is switched (Refer to Section 12.3.3 "Near- pass function").

(2) Deceleration stop conditions during continuous path control

Deceleration stops are basically not carried out in continuous path control, but the machine will carry out a deceleration stop to speed "0" in the following cases (a) to (d).

(a)When the operation pattern of the positioning data currently being executed is "continuous path control: 11", and the movement direction of the positioning data currently being executed differs from that of the next positioning data. (Only for 1-axis positioning control (Refer to the "Point" in the next page.))
