MOTN-019: Robot Near Singularity

The robot has reached or is passing through a singularity during Cartesian motion.

What it means

The robot has reached or is passing through a singularity during Cartesian motion.

Common causes

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

  1. A programmed Cartesian (linear) path passed too close to a singularity.
  2. Cartesian jogging brought the robot near the J1 singularity.

How to fix it

  1. Reteach the taught position to keep the path clear of the singularity, or switch that move to Joint motion.
  2. Use Joint jog to move the robot out of the singularity.
