Hardinge KL-1

Everything seems to be fine with the main motor. No nasty noises.
The VFD indicates about 2A when running.

Now to re-do the wiring.

I wanted to use as many of the original switches and contactors as possible, but knew that most of the wiring would have to go.

The control box wiring looked like this when purchased:



I'll keep the original high/low speed switch, main power switch, and as many of the contactors that I need.
Wiring from the terminal blocks at the bottom will stay, and I'll just wire the new control into them

So, here is some of the top half removed. The new transformer mounted, together with two of the VFD's.
The top grey one is the FR-D740 for the main motor, the white one to the right is for the speed change motor.
