3) When the version is Ver.1.30 or later "interrupt 1-speed constant quantity feed (constant position stop
mode) shortest allowable stop" is enabled. (Refer to Fig. B.)
If the system cannot stop at the target position (target address 1) with the setting value of deceleration
time, it stops at the target position (target address 1) using a deceleration time
automatically. (Refer to Fig. B.)
However, if the travel distance to the target position (target address 1) after the interrupt input (INT0)
turns ON is shorter than the travel distance required for a sudden stop, the system passes the 1st target
position (target address 1), decelerates, and then stops at the 2nd target position (target address 1).
(Refer to Fig. C.)
