Programming Example
Pause Bits
These bits are used to temporarily pause program execution.
When a bit is turned ON, the block being executed will be interrupted and any
axes that are operating will be decelerated to a stop.
Operation is restarted by turning ON the Cycle Start Bit. The program that
was paused will be executed as long as the Program Number Read Bit is OFF.
Operation of the Cycle Start Bit is disabled as long as the Pause Bit is ON.
(The program won’t be executed when the Cycle Start Bit is turned ON if the
Pause Bit is ON.)
The Pause Bits have a lower priority than the Forced Block End Bits. If both of
these bits go ON at the same time, the block will be ended.
Keep the Pause Bit ON until the Program Execution Flag turns OFF.
