Corrective Action
Use a Motion Axis Stop (MAS) instruction to stop the axis or configure your
instructions like this example.
Why Is There a Delay When I Stop and Then Restart a Jog?
While an axis is jogging at its target speed, you stop the axis. Before the axis
stops completely, you restart the jog. The axis continues to slow down before it
speeds up.
Example
You use a Motion Axis Stop (MAS) instruction to stop a jog. While the axis is
slowing down, you use a Motion Axis Jog (MAJ) instruction to start the axis
again. The axis doesn’t respond right away. It continues to slow down.
Eventually it speeds back up to the target speed.
Use the same acceleration rate as the
instruction that stops the axis.
Or use a lower acceleration.
Use the same acceleration rate as the
instruction that starts the axis.
Or use a higher acceleration.
