Normally a shielded twisted pair wire should be used, but right now I have what I have, which is just a lamp wire, between my PC and the VFD. This was about a week ago, however continued work resulted in finding solutions in Mach3 brain and I have now solved everything I needed to solve and abandoned the macropump use.Īny VFD can be controlled with my solution, using a simple USB - RS485 converter and two wires connected between that and the VFD. Then about a week ago I discovered the unknown territory of Mach3 brains and thought that THIS IS IT Of course, this ended pretty quick after a day or two in a disappointment because I found some serious limits in the functionality and implementation, so I started thinking that part of my problem can be solved by a macropump macro, which is acceptable if necessary and much faster than I can write a plugin in C.
With my 40 years of engineering career, mostly in the fields of datacom related and computing business, using digital inputs and outputs and a crappy, unreliable and nonlinear 0-10V DAC felt very strange and stone age, but not knowing better, I thought, this is what most people use, so this MUST be the best way. Some of those who try a different approach are trying to find plugins for their VFD and that is not always possible and definitely not necessary, because Mach3 has a ready made function for this, which is fairly easy to adapt to any VFD, but it is pretty badly documented. I dont know why so few people are interested in other ways of controlling the VFD, perhaps it is because they think it is too complicated, or dont know better and do as they always done, or as others seem to do. That simple straight forward solution has been around for ages and widely spread, but has some disadvantages because it demands a good and reliable, very linear 0-10V PWM generator and several wires, all these may be noise sensitive, causing unexpected behavior as well as using up several digital inputs and outputs of the VFD and the BoB.
