6 SEQUENCE PROGRAM USED FOR POSITIONING CONTROL

(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.

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 [XC, XD, XE, XF] is OFF), the

interrupt request during continuous operation is not accepted. It is cleared to 0
at a start or restart.
