Actually Peter and Andy. I have a 400v to 240v stepdown transformer on the lathe at the moment as fanuc uses 240v drives in Japan.
The transformer is massive So I already have 240volts ac three phase power in the machine. Just need to rectify it I think. I have no idea currently how to rectify ac into DC but it can't be that hard. Just need to make sure I get it right lol. High voltages are dangerous. The fanuc 10s motor is rated for 150v at 7amps I think it's a 8pole motor max rpm is 2000 It's looking better for the 8i20 drives. I think they are a bit harder to set up though than a normal servo as I have to learn how to use bldc. I would love to learn this stuff though. Do you guys feel like coaching me through setting them up? This will be my 3rd machine I have set up. So I'm getting better at Hal. And shouldn't need to much hand holding. also what mesa cards are best for interfacing with 8i20 cards? from what I understand they are a bit different to the normal drives 0-10v stuff Regards On Thu, Jun 4, 2020 at 9:43 AM andrew beck <[email protected]> wrote: > Hey guys > > I have been looking at the mesa 8i20 servo drives and thinking about using > one to control a 3.45 kw heidenhain motor I have here > > the max power the servo drive can control apparently is 2200w so the > servo drive is slightly under powered. > > http://store.mesanet.com/index.php?route=product/product&product_id=149 > > just wondering who has used them now. > > I am possibly getting another 5 ton big cnc mill and thinking of using > the mesa 8i20 for the servo drives.
