What the 10003 alarm means

The joint could not follow the commanded trajectory — following error exceeded the limit — so the controller halted motion. This is one of the faults our repair team handles on AUBO i-series / C-series (ARCS SDK) systems — the cause is usually identifiable within the first on-site inspection.

Most common causes

  • Obstruction or collision in the path
  • Payload above rating
  • Brake dragging on the joint
  • Encoder signal intermittent
Field note: the first item on this list is what we find most often on real machines. Check it before you go deeper.

Step-by-step field fix

  1. Clear obstructions and check for damage
  2. Correct the payload configuration
  3. Verify brake release on the joint
  4. Check encoder/cable condition through the dress pack
  5. Re-run at reduced speed and watch tracking error in diagnostics
Safety first: never bypass safety circuits or force contactors closed. If the alarm involves E-stop chains, brakes or drive power, and you are not a trained robot technician, contact a professional — wrong moves here can cost you a robot or an injury.

Frequently asked questions

QWhat does the AUBO 10003 alarm mean?

The joint could not follow the commanded trajectory — following error exceeded the limit — so the controller halted motion. In field practice it belongs to the motion & path family of faults.

QCan I clear a AUBO 10003 alarm myself?

Sometimes. Work through the step-by-step checks on this page — the first listed cause is what we find most often in the field. If the alarm returns after two attempts, or the fault involves power, brakes or safety circuits, stop and call a qualified robot service engineer.

QHow fast can a Henghuan engineer help?

On-site response in the Pearl River Delta within 30 minutes to 3 hours, across mainland China in 1-3 business days, and worldwide within 2-5 business days. Remote diagnosis by phone/WhatsApp/video is available immediately.
