Buffered during single axis operation

Multiple started FBs are buffered and wait (Busy = TRUE) until the on-going FB is completed. After the on-going FB is

normally completed, multiple started FBs are performed in the order of being buffered.

Conditions to determine completion are different depending on the MCFB, and the FB may not be in the stop status with

speed 0 at completion. For details, refer to each FB specifications.

In MCv_SpeedControl, the FB is determined that it is completed when InVelocity turns TRUE, and the following buffering FB is
