Hello all

I installed a 0-10v signal from my MESA 7i77 board to the vfd to control rpm and my XHC-W04B-6 pendant will enable the spindle but wont tell the spindle to turn at default spindle speed set in the ini file .  Any help would be appreciated.

Regards 
James 

This is the only thing that works smoothly for me.

Ahh, well, so it goes. I've ordered a 7I76U because I think that the D models were actually going to be more difficult to wire anyways, as I'd like some sourcing outputs.  I'll see about getting an RMA for the 7I77D I have, and can function test the existing 7I76D when I get the new 7I92TM.  5 axis + spindle and 48 I/O pins should be plenty to get this mill up and running, and that leaves me some boards to experiment with in the future

Thanks for the quick replies, nice to keep momentum up on the project!

of course here are my files, I tried one configuration with fb that works but I still don't know in practice if it works well, definitely try it if you are able to see why this one doesn't work. thank you very much

This is old machine, so it's probably an old board, so it's probably a 7i92M (sans "T").

Just for future reference, the age of machine will have no bearing on whether it's a T or sans T. It will depend on the period the card was bought. History will show the the Spartan 6 FPGA was hard to get at one stage, hence the switch to the Trion device.

In real life, despite what the "maker community" will tell you, a capacitor isn't the end all and be all. Also you'll really need to know the load current,ripple and frequency for determining the capacitor reqired, which will differ from application to application, just mentioning this as a PSA.
What is the best option is a quality PSU, yep a bench PSU is great for testing, a genuine Meanwell or Weidmüller (depending on where you are not as easy to get hold of and a little more $$$) supply wont let you down once installed, I only mention these as these are the ones I've been using for eons, all DIN rail mount. I usually switch the computer PSU on, then the MESA boards PSUs, then the stepper power and finally the servo driver for the spindle. To tell the truth with all the relays (self latching) and stuff the PSU wiring was way more complicated than maybe what is should have been. But each circuit controlling the mains is independently controlled.
Regarding powering the 7i77/7i776 or any other DB-25 daughter I've been powering mine(7i76/7i74/7i73/7i83)by the DB-25 connector, found it to be a simple and solid solution. The 7i73 & 7i83 are also powered by the smart serial cable via the 7i74.

I will try today the potentiometers for feed and spindle, I noticed when I opened the panel that this is not ``mpg'' but the same potentiometer:)..its power supply is connected to the power supply of the potentiometer for feed and speed and its mass is connected to the physical buttons jog+ and jog-..it probably had some logic in the plc of the old controller, I will have to replace it with a class mpg of 100ppr it seems:)

thank you very much, I will try this tomorrow related to hal file, this is an example for a spindle, I believe it is similar for feed? I also need information on where this file should be located, in which Linux folder ``hist.comp``? and do I need to add any line to the ini, except halfile=...

I think the tricky part  with feed override and spindle speed override
is to get along with the GUI

yes, I knew about the 7i96s, yes, I had connected two independent ones when I had a lathe that worked in sync... here I will find an example for one via the axix selector,as a pendant I think it's not a problem. My problem is that I don't know how to connect potentiometers in the hall (if the first three inputs in mode 3 are analog on the 7i77?) how can they recognize it in the hall as spindle override and feed override?

2.9.0. I didn't have a 7i92 with me, so I used a 7i96s as the main card, which turned out to be better because I'm planning two additional axes later that will use steppers...now about mpg, maybe and I have an example to try...but I didn't have any experience with connecting potentiometers for feed and spindle override, and any Hal example would be valuable to me.

..in connection with the machine retrofit #338210
, I would like to include the hardware buttons in the configuration, also calculating the mpg. I have a lot of free inputs (all on 7i96s) and about twenty on 7i77 where I left the first three free as I understood that they are analog because of the potentiometer) now I need a suggestion, since dont have schematic for the old controller and not for the buttons, I think they are all on 24vdc including mpg. the outputs that I connected to 7i77 lit the bulbs of these buttons at 24v. should I try the configuration in terms of the mpg pendant for selector increments and mpg, and for spindle and feed override how should I connect? Thanks

Hi Tom, I did my 400E with Mesa 5i25 (PCI), 7i77, and 7i84,  but back then the 7i97 did not yet exist.

If I were starting again, I would use the 7i97 and 7i84. I hard wired everything in my Bedienpul. Today I would use a 7i73 to interface that.
Does your 400W4 still have the 18 speed gearbox, or does it use a big DC servo on the spindle with just a back gearbox?

I would also suggest you take a look at Peter (Talla83 on Youtube's) Pendant.


Peter hat die beste Mesa Info auf DE.
Cheers,

Thanks, I'm on the way to a solution for the drivers, what's left of the cables is clear to me, and the rest are: analog +-10v signals, one 25pin input cable, which are partly connected as soon as the machine is turned on, and partly I realized which ones are for homing and for inductive sensors from the tool. and this 25 pin output cable remains, there are a total of about 10 outputs, my plan is to activate them all manually, together, by hand out of 7i77card, to see what will happen on the other side of the machine where this TB3 (see schematic) terminal block is. the cable from the pendant remained, that is, the one  from external buttons to the controller, I mean jog, feed override, spindle override, axis select, step select, estop. I will have to find a way to activate the K1 switch, it turns on the drivers, but also to connect the estop to turn it off. My question is, do I need analog inputs for the pendant later, or could a configuration be made using buttons and potentiometers that would support mpg, potentiometers and buttons with digital inputs?
