What the 30001 alarm means

The collision-detection function sensed unexpected external force and stopped the robot. Codes 3xxxx are runtime protective events. On a cobot this is a protective stop, not a damage report. 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

  • Contact with a person, fixture, or workpiece
  • Sensitivity set too high for the process
  • Wrong payload/tool data skewing the force model
  • Snagged external cables or hoses
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 the contact and inspect for damage
  2. Verify tool weight and center of gravity
  3. Tune collision sensitivity only as the process requires
  4. Re-route external cabling
  5. Restart from a safe position
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 30001 alarm mean?

The collision-detection function sensed unexpected external force and stopped the robot. Codes 3xxxx are runtime protective events. On a cobot this is a protective stop, not a damage report. In field practice it belongs to the safety chain & e-stop family of faults.

QCan I clear a AUBO 30001 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.
