We now have a Juki DDL-5550-4

SC-120 controller
Type D1CHCS servo drive/Electronics box

The machine won't turn on and shows no signs of power after being plugged in. (It just didn't show any signs of life one morning according to the previous owner).
We suspect that something with the driver to be wrong. Hopefully we can just fix it but plan B is a new vdf motor controller.

What needs to be done

  • sew a protective hood so it won't get all dusty.
  • document the wiring
  • afterwards unmount the driver and try to diagnose the problem
  • Readable
  • test (only slowly without oil
  • find out what type of oil is needed
  • buy oil
  • refill with oil

Ich hab mir sie mir am 02.12.2024 das erste mal angeschaut und versucht die offensichtlichsten Stellen zu überprüfen.

  • Der Ein/ Ausschalter funktioniert
  • Die Sicherung ist noch intakt
  • Ich meine auch das der Motor Strom bekommt

Eventuell können wir uns überlegen die Nähmaschiene mal ohne die Automatik zu testen
