[3] Continuous path control
(1) Operation of continuous path control
(a) A speed change is made between the command speeds of the "positioning
data No. currently executed" and "positioning data No. to be executed next"
without a deceleration stop.
A speed change is not made if the current speed is equal to the next speed.
(b) Dwell time will be ignored, even if set.
(c) In operation performed by continuous path control (operation pattern "2"),
the positioning control of the next data No. is automatically exercised.
Always set the operation pattern "0" in the last positioning data to terminate
the positioning control.
If the operation pattern is continuation ("1" or "2"), operation will continue
until the operation pattern "0" is found. If the operation pattern "0" is not
found, operation is performed up to the positioning data No. 10. If the
operation pattern of the positioning data No. 10 is not terminated, operation
is started again from the positioning data No. 1.
(d) A speed change at positioning data No. switching is made at the beginning
of the next positioning control.
