What the 0x000034 alarm means

Joint motor winding temperature exceeded the limit; the joint is inhibited to prevent insulation damage. This is one of the faults our repair team handles on JAKA Zu / JAKA Pro cobots (APP) systems — the cause is usually identifiable within the first on-site inspection.

Most common causes

  • Duty cycle too aggressive for the joint rating
  • Ambient temperature too high
  • Payload above rating
  • Joint held at high torque (clamping) for long periods
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. Let the joint cool — forced air helps
  2. Reduce speed, payload, or holding time in the program
  3. Check the real payload setting in the APP
  4. Improve cell ventilation
  5. Re-test and monitor joint temperature in the diagnostics page
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.
