What the D1562 alarm means

The incoming AC supply measured at the power sequence board is above the permitted range; the controller protects itself from overvoltage. This is one of the faults our repair team handles on Kawasaki E / F / C series (AS language) systems — the cause is usually identifiable within the first on-site inspection.

Most common causes

  • Plant supply voltage genuinely high (tap changer issue, light-load period)
  • Transformer tap set wrong
  • Voltage-sensing circuit fault on the power sequence board
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. Measure the actual incoming AC voltage at the cabinet
  2. If plant voltage is high, correct it at the transformer/feeder
  3. Verify the controller transformer tap matches the local voltage
  4. If the supply measures normal but the alarm stays, replace/check the power sequence board
  5. Clear the root D-code first when multiple power alarms appear together
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 Kawasaki D1562 alarm mean?

The incoming AC supply measured at the power sequence board is above the permitted range; the controller protects itself from overvoltage. In field practice it belongs to the drive & power stage family of faults.

QCan I clear a Kawasaki D1562 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.
