MOTN-148: Motion Groups Can't Move Concurrently

Two motion groups couldn't stay synchronized because one group had to replan its path.

What it means

Two motion groups couldn't stay synchronized because one group had to replan its path. Both groups slow down as a result.

Common causes

Ranked by what technicians most often find, most likely first.

  1. One motion group replanned its path, breaking synchronization with the other group.

How to fix it

  1. If the resulting slowdown on both groups is acceptable, no action is needed.
  2. If the slowdown is not acceptable, re-teach the path.
