Aborting during single axis operation
On-going FB is interrupted and the next FB is executed.
Since a buffer is not used, an error does not occur even if two of the on-going FBs have already been in buffering, and the FB
is executed. (All FBs during buffering are interrupted.)
When omitting to specify the buffer mode, this operation is performed.
An operation example when Aborting is executed to the on-going FB1 with the linked start FB2 is shown below.
