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 13.3.3 "Near
pass function").
(2) Deceleration stop conditions during continuous path control
Deceleration stops are 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 (c).
(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
"Points" in the next page.))
