Table 10- 89 Example 1 - If the parameterized velocity is reached and maintained
JogForward
JogBackward
The task is started with a positive edge at the input parameter "JogForward" or "JogBackward".
② While the task is active, the output parameter "Busy" indicates the value TRUE.
③ When the parameterized velocity is reached, the output parameter "InVelocity" changes to TRUE.
④
When the input parameter "JogForward" or "JogBackward" is reset to the value FALSE, the axis motion ends. The axis
starts to decelerate. As a result, the axis no longer moves at constant velocity and the output parameter "InVelocity"
changes its status to FALSE.
⑤ If the axis has come to a standstill, the motion control task is complete and the output parameter "Busy" changes its
