3. Interrupt 1-speed constant quantity feed (constant position stop mode)
(in Ver. 1.10 or later, when "ring counter setting" in the current address (b3 of BFM #14002/
#14202) is ON and "mode selection for interrupt 1-speed constant quantity feed" (b6 of BFM
#519/#619) is ON)
The system operates as follows when 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 deceleration stop:
1) When the version is earlier than Ver. 1.30
If the system cannot stop at the target position (target address 1) by the setting value of deceleration
time, it passes the 1st target position (target address 1), decelerates, and then stops in the 2nd target
position (target address 1). (Refer to Fig. A.)

"acceleration/deceleration mode."
2) When the version is Ver.1.30 or later and "interrupt 1-speed constant quantity feed (constant position
stop mode) shortest allowable stop" is disabled, the system performs in the same way as versions earlier
than Ver. 1.30.
