ABB Error 50026 — Close to singularity

Warning

ABB 50026 (“Close to singularity”): The commanded path passes near a kinematic singularity (typically wrist alignment).

Updated 2026-09-17 · LogrobotLM reference

What it means

The commanded path passes near a kinematic singularity (typically wrist alignment). Joint speeds explode locally; the controller degrades or stops the motion.

What to check

  • Re-teach the path to avoid the singular zone, or use SingArea/joint moves through it.
  • Small tool re-orientations near vertical wrist positions are the classic trigger.
