Fig. 9.3 Operation during continuous path control (Standard speed switching mode)

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.))
