Note
When executing a positioning instruction from the MC program, all of the axes
being used must be servo-locked (Servo Lock ON Flags ON), so be sure to add a
condition like R4 in the program example above.
6-5-4 Word n+1 Bit 04: Forced Block End Bit (Task 1)
This bit is used to force termination of the block being executed; it is valid only
when the mode is set to automatic mode. When a block is terminated, the
remainder of the block is canceled. Program execution will restart from the next
block when restarted with the Cycle Start BIt.
Any axes that are operating will be decelerated to a stop. If the block being
executed is waiting for an M code reset, the M code will be cleared to 0, the M
strobe will be turned OFF, and then program execution will be stopped.
Operation of the Cycle Start Bit is disabled as long as the Forced Block End Bit is
ON. (The program won’t be executed when the Cycle Start Bit is turned ON if the
Forced Block End Bit is ON.)
The Forced Block End Bit has a higher priority than Pause Bit (n+1 bit 05). If both
of these bits go ON at the same time, the forced block end command will be
executed. Keep the Forced Block End Bit ON until the Memory Run Flag goes
OFF.
The Forced Block End Bits for task 2 (bit 04 in word n+3) operate in the same
way.
Signal
The Forced Block End Bit settings have the following functions.

Function
↑
(OFF-to-ON)
Terminates the block being executed.
ON
As long as the bit remains ON, the program won’t be executed
when the Cycle Start Bit goes ON.
