Motion Control instruction "MC_MoveJog"

Description
An "MC_MoveJog" job is started by setting the "JogForward" or "JogBackward" parameter.
The job objective is fulfilled when the assigned velocity is reached and the axis travels at
constant velocity. When the assigned velocity is reached and maintained, this is indicated in
the "InVelocity" parameter with the value TRUE.
The job is complete when the "JogForward" or "JogBackward" parameter has been set to the
value FALSE and the axis has come to a standstill.
The behavior of the parameters is presented below for various example situations:
The assigned velocity is reached and maintained
If the Motion Control job has been performed up to the point of reaching the assigned
velocity, then this is indicated in the "InVelocity" parameter with the value TRUE.
Jog mode is controlled by the "JogForward" parameter.
①
The job is started by setting the "JogForward" or "JogBackward" parameter.
②
While the job is active, the "Busy" parameter shows the value TRUE.
③
When the assigned velocity is reached, the "InVelocity" parameter changes to TRUE.
④
When the "JogForward" or "JogBackward" parameter is reset, the motion of the axis ends. The axis decelerates. The
"InVelocity" parameter changes to FALSE.
⑤
If the axis has come to a standstill, then the Motion Control job is complete and the "Busy" parameter changes to
FALSE.
