3 kW AC Servo Drive From a 4 Ton Stone Polisher – Isolation, Day 32

I scavenged a old 4 ton stone polisher machine for the best components and got off with a 3 kW AC server motor + drive, 4+0.55 kW variable frequency drives. In this video I try to make the servo motor run despite missing a control panel that was gone from the machine.
