MOTN-153: Joint Move Too Fast Near Singularity

A joint angle move exceeded the allowed tolerance.

What it means

A joint angle move exceeded the allowed tolerance. The motion likely became too fast because the path routes through or near a singularity point.

Common causes

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

  1. The taught path passes through or close to a singularity point, forcing a rapid joint angle change.

How to fix it

  1. Reteach the point to remove the singularity from the path.
