Long story short, I need to run my mach3 mill turn machine with an rs485 plugin controlling the spindle. I'm looking to upgrade my Chinese 2.2kw spindle to an atc unit. I've already talked a bit about this on mach3 sub to see if the rs485 plugin will work with other vfd's, but no answer on that yet. The easiest solution would be to just keep running huanyang with my new atc spindle because the plugin for huanyang works well with my dual spindle mill turn setup.
When I contacted the seller of a couple atc spindles, a 2.2kw and a 3kw, I asked if it's ok to pair them with a huanyang (both spindles are 400hz) and the seller said "no you need better vfd, huanyang is cheap". Is there a specific reason why the huanyang won't run these spindles Well even though they seem to work fine with common 2.2kw non atc spindles? Or is the seller just saying that because they are relatively cheap compared to other vfd's?
