Mach3 Controlling Huanyang HY02D223B 2.2KW VFD

Yes it is possible, either by configuring it for digital input which allows you to select (I think) 8 different speeds or by using the anologue speed control input and mach's PWM output which may require smoothing. I'm sure you'll find it if you look on CNC zone. I've not done it yet as I prefer to control it myself.

Here's the English-ish manual which should clarify things:

Jonathan,


Even after reading the manual I could'nt solve the problem. What you really mean by your first sentence of your comment, can you be somemore specific ?

I'm currently about to wire one of these inverters to a CSMIO-IP/M for spindle speed and direction control. The connection diagram for the inverter shows separate grounds for analogue and digital signals. Does anyone happen to know if these can be connected to provide a common ground? If so, I could get away with a single 4-core CY cable between control box and inverter (F/R/Speed/common ground) but otherwise I shall end up with two cables (as I only have 4-core CY and not 5-core!). Not difficult if I have to go the two-cable route but it would be a little tidier if I could get away with just one.

Neale - I think by asking you know the answer already - it' rarely a good idea to mix analogue and digital grounds. It might work, but it's not designed to.

Of course, an alternative is a RS422 interface between the controlling PC and the inverter - I'm not saying this is the best solution but it can (in my experience of dodgy earths) avoid some analogue noise, and requires only a 2-wire interface and a £3 USB device to provide digital speed and direction control.

Neal they are separate grounds but you don't need 5 core 4 cores is enough. Heres how you wire it to IP-M controller.

Starting with On/OFF. Take DCM to Pin 25 then FWD to Pin 12 or 13 depending which Output relay you want to use.
Speed Control: ACM to Pin2 on Analog Output. V1 to Pin1

It's that easy.

Cheers Dean, I'm just looking at this as I'm about to wire mine to the IP-M at last....

[Neale]

Thank you for that, Jazz. Yes, indeed, the wiring is that easy, and essentially that's exactly what I was going to do. The difference was that I was going to wire in the REV connection as well, hence the need for four cores. But thinking through what you wrote, I realise that in the four years I've been using it, I have never ever used "reverse" on the spindle, and I can't imagine why I ever would. Drop that, and I can happily use one piece of CY for the lot. Sometimes you can be too close to a problem!

Thanks again - I'll get that wired and tested later.

DONT DO THAT.!! . . . It's dangerous to run Collet Spindle in reverse.? Think about it for minute and will become obvious.!!
