11.3 Single-axis Operation
In the program example, stop operation is started at the rising edge of the "Execute" flag of
"MC_Stop".
The "Busy" flag is set to TRUE during execution. While the "Busy" flag is set to TRUE,
"MC_Stop_0" must be called every cycle. Otherwise, the operation will terminate with an error.
When the stop operation is completed, the "Done" flag is set to TRUE.
Unless the "Execute" flag of "MC_Stop" is set to FALSE, axis control cannot be executed by
other function blocks.
