What the 1030 alarm means

Drive heatsink temperature exceeded the limit; the unit derates or shuts down to protect the power electronics. This is one of the faults our repair team handles on EFORT EC2-S controller + TSINO drives systems — the cause is usually identifiable within the first on-site inspection.

Most common causes

  • Cabinet fan failure
  • Clogged filters and heatsink fins
  • High ambient temperature
  • Repeated overload resets without cooling time
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 drive cool before resetting
  2. Check cabinet fans and airflow
  3. Clean filters and heatsink fins
  4. Lower cabinet ambient temperature
  5. Review duty cycle for sustained peak loading
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.
