Troubleshoot Axis Motion
This section helps you troubleshoot some situations that could happen while
you are running an axis.
Why Does My Axis Accelerate When I Stop It?
While an axis is accelerating, you try to stop it. The axis accelerates for a short
time before it starts to decelerate.
Example
You start a Motion Axis Jog (MAJ) instruction. Before the axis gets to its target
speed, you start a Motion Axis Stop (MAS) instruction. The axis continues to
speed up and then eventually slows to a stop.
