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.))
