Chapter 6 Sequence Program Used for Positioning Control
(2) Even if the stop command is turned ON after executing the "continuous
operation interrupt request", the "continuous operation interrupt request"
cannot be canceled.
Thus, if "restart" is executed after stopping by turning the stop command ON,
the operation will stop when the positioning data No. where "continuous
operation interrupt request" was executed is completed.

(3) If the operation cannot be decelerated to a stop because the remaining
distance is insufficient when "continuous operation interrupt request" is
executed with continuous path control, the interruption of the continuous
operation will be postponed until the positioning data shown below.
•
Positioning data No. have sufficient remaining distance
•
Positioning data No. for positioning complete (pattern: 00)
•
Positioning data No. for continuous positioning control (pattern: 01)

Continuous operation
interrupt request
Even when the continuous operation interrupt is requested,
the remaining distance is insufficient, and thus, the
operation cannot stop at the positioning No. being executed.
(4) When operation is not performed (BUSY signal is OFF), the interrupt request
during continuous operation is not accepted. It is cleared to 0 at a start or
restart.
