“Please rush this as fast as possible! We are down!”
We get it! We don’t like downtime either! It’s costly! Time to jump into action! Let’s get this Sanyo Denki Drive CFZ0A100DR4601 with error codes back to working order.
So what was wrong with this old and very dirty 
drive unit?
Mostly just that – age and dirt, lots of build up! There’s no getting around that! Testing showed numerous components had failed. To repair this drive would mean virtually rebuilding it. And that’s what our customer needed us to do!
We replaced many components including:
- 10 capacitors on all control boards, bus-cap, and IGBT
- installed a new fan
- reworked the gate circuits
- tested and repaired the breaking /regenerative circuits
- tested and repaired the relay’s contacts
- tested the entire unit
- Did we mention it was really dirty? Lots of cleaning to get rid of all the build up!
In just a few days this unit was back to work – practically brand new again! With a two year warranty! And best of all, our mid-west US customer reported success after installing their rebuilt Sanyo Denki drive! Their CNC shop was back to work machining both gray and ductile iron! Good stuff! We love our CNC machining customers!
