[CNC] Anilam 3200mk Help

It looks like you can use 3 wire control (momentary contact pushbuttons) for start and stop. For forward and reverse, it seems to require a maintained contact switch. See section 4-5-9, page 212. Any of the inputs can be programed for STA, STP, and F/R. I would use S1, S2, and S3 for these functions. It takes a while to wade through that manual, it's not written for the first time user.

Aint that the truth! I read through there a few times in bed and my alarm woke me up in the moring haha.

3 wire control seems a bit odd to me. Now that we are in DC shouldn't it just take a two pole switch? connect the poles to turn it on? What is the third pole for?

Or are three poles for a FWD/REV switch with a power input pole?

Once you get the controls figured out, I would still use a remote pot for speed control. The little dinky knobs on the VFD's seem to be hard to operate with greasy fingers. I made a custom dial for my pot with movable stops to preset an operating range for the job. I calibrated the dial right off the digital tach, and as you can see the pot is quite linear. I don't pay much attention to the tach anymore.I have several jobs that runs tools at 2 different speeds, and it very handy to just flip the dial from one stop to the other without having to look.View attachment 122839

That's a neat idea thanks. I thought with SVC I would have a tach feedback or output on this thing, but maybe not. I don't have a dial on the front, increase or decrease is push button. I'll have to look into the pot idea, that would be nice.

On the CNC power supply front, does anyone know what colors coming off the power supply need what for voltage? That's the next step on that part and I'm at a dead stop until I figure that out.

This is a standard non VFD 3 wire control for a motor starter. And it's is incorrect, the contact labled Ma should be Normally Open, not normally closed as shown. I'm just too tired to go find another diagram. The 3rd wire is between the buttons.



Ignore everything on the diagram below except the stop and start buttons. Note the 3 wires going to them.

ah ok. Seems like two switches with a shared input to me, but I see the principal.

I think I'm going to remake the control box and mount it on the front of the head for easy access. I need to figure out what switches I have in the box now, as I don't think they are what I need to run the VFD.

Did anyone see how to use a pot for speed control? I didn't but more than likely it is called something I'm not familiar with.

Time to go make a video!

The start and stop buttons should work, but you need a maintained contact for FOR/REV as far as I can tell.

A few thoughts, you mentioned setting the VFD to go up to 120Hz, I would not do that on a variable speed head. 4200 is fast enough for your spindle bearings.

The Power Feed Start is a switch as well as an indicator. It may be stuck. That is wired to the Anilam relay board and enables the drives. In the drive panel, Anilam used black and white for the 120V AC power. In my panel they used orange (+) and gray (-) for the DC power to the drives. The wires coming from the power supply: Who knows, but I'm guessing you might find the voltages silk screened onto the board.

great! I'll pull it to investigate in the house this afternoon.
