What the 0x13 alarm means

In ARC or JUMP_MOVL mode the planned points are duplicated, so the trajectory cannot be constructed. Documented in the official Dobot ALARM description: the alarm is set when an ARC has repeated points or a JUMP_MOVL start equals its end. This is one of the faults our repair team handles on Dobot Magician / MG400 / M1 / CR (DobotStudio) systems — the cause is usually identifiable within the first on-site inspection.

Most common causes

  • ARC mode: two or three of the taught points are identical, so no circle can be fitted
  • JUMP_MOVL mode: start point equals end point with no translation segment
  • Copy-pasted points in the program without re-teaching
  • A vision or offset routine writing the same value to two points
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. Check the taught points for duplicates and re-teach distinct positions
  2. Verify any offset/vision calculations that feed the points
  3. Save the corrected points
  4. In DobotStudio, run the clear-alarm script from the script control module
  5. Re-run the motion at low speed to confirm
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 Dobot 0x13 alarm mean?

In ARC or JUMP_MOVL mode the planned points are duplicated, so the trajectory cannot be constructed. Documented in the official Dobot ALARM description: the alarm is set when an ARC has repeated points or a JUMP_MOVL start equals its end. In field practice it belongs to the system & program family of faults.

QCan I clear a Dobot 0x13 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.
