I have finally got a bit more progress on my machines.
I bought most of the parts to do the VFD conversion but was missing a few critical bits.
As I was in no hurry, so it went on the back burner until I was ready to tackle it.
The last few weeks I've been receiving packages from McMaster Carr and Automation Direct, about eight separate packages as it turns out, always one last thing I forgot, so another order.
Here is the Hubble 14" X 12' X 8" box for my PM 935TS Mill, I was going to put the fan in the bottom and vent out the top left side but I was concerned about the amount of cables I needed to bring in through the bottom of the cabinet, so I went with fan on lower left and vent top left.
That gives me plenty of room for the cables coming in the bottom but I had forgotten that I was going to install the 120VAC outlets on the lower left of the cabinet. Oh well not the first change I needed to make on the fly.
I cut two 4" holes, lots of chatter when using holes saws and it's hard to get the drill to go slow enough without grabbing and stalling, got it done after resting the drill a few times..
I mounted the VFD a while back but now realized that I needed to move it so I flipped the back panel around and redid the mounting closer to the top left side.
The old holes should be covered by the DIN Rail.
Here is the box, almost finished the layout, I also relocated the braking resistor to the top of the cabinet as I had it mounted on the left side previously.
Another view showing the Main Power Disconnect Switch mounted on the side of the box, which will face forward.
I may install a pilot light above it at some point, so I can see if it's powered up from a distance before I leave the shop.
The 24 VDC power supply is a 60 Watt unit from Automation Direct.
Here's the control pod, just need to get this wired and mounted and labels for each switch.
The layout is as follows,
Top - ebay tach
Top Swtiches, Left - Speed Control, Right - Forward/Rev switch
Middle, Green _ Start, Red - Stop
Bottom - Emergency Stop
That's about all for now.
