So I have the pretty common 2.2kw 24000 rpm water cooled spindle and HY VFD. I'm trying to get this to run using the smooth stepper and the c62 board from cnc4pc.

I have confirmed I get the analog signal at the VFD up to 10v depending on my spindle speed I set. I can verify on terminals that the relays on the c62 are working right by checking ohms on VFD terminals indicating open and closed. The relays are in the right sequence for cw and ccw. I used international mode on c62 and set parameters in drive for this mode.

I can't get the VFD to work!!! I can manually control it with the VFD controller, but nothing in Mach3.

I have the proper wires ran for for/Rev acm, dcm, and vi (0-10v)

My VFD just shows a flashing f000 or f400 (setting dependent) and won't start when pd001 is set to 1 or external control.

Now searching the world wide Web for hour and hours and hour...possibly days now, I have found a set of about 100 different instructions on settings so far nothing a success, but seems like most are for people controlling with VFD control and not pwm.

Anyone point me in a direction or had experience in this drive?

There is a couple of plug-ins for the Huanyang using a Modbus connection via a 9 pin com port or USB adaptor.
See the Mach forum site.

How does modbus tie into system? I mean is it pretty stable vs going through motion controller? Run away spindles?

It is a plug-in installed min Mach, all commands are sent in a serial fashion, the status is constantly monitored so if there is loss of communication or other error etc, the drive throws an E-stop.

Oh nice. I may have to look into this. I've been trying to set up using the pwm feature on my c62 Bob but thinking my problem lies in the vfd parameters itself

This is the one I used.

A new Huanyang VFD plugin

Any real advantages to rs485 vs dig inputs using pwm on the bob?

Check PD070. It should be 0 (default) - analog input 0 - 10 V.

I have a new HY VFD and the RS485 is no longer present it appears to have been removed from later models.

Mine is new as well. Bought less than a year ago.

Which settings did you follow?

Not sure if this will help, but here are my notes on mine I saved to get this going.

Note- The Huanyang Analog input FREQ low and High must be set first.
PD072 and PD073. Mine are 90hz and 9hz for now. This was my problem originally when I could not get the 10k pot or the DAC to work w/ the speed
If you continue to have problems, Check your setup w/ a 10K pot. It should work and then you can disconnect the pot and connect DAC out. Remember and note DAC com is the top lead on your DC-AIO
Dac com to ACM
Dac 0-10V to VI

NExt- The spindle speed in CNC11 and pendant control may run backwards. + went DOWN , while - went UP in RPM. SOLVED:
There is a manual misprint, PD072 and PD073 are written two different way's in the manual. 1 pages lists as PD072/73 as Low/High while another as High/Low.
Swap your values. PS0072 is the HIGH freq and PD073 the low freq on my unit

You do need to enable for REVERSE. PD0023 = 1. Reverse enable.

Awesome. I'm taking a 3 day weekend out of town so Sunday I'll be messing with thus

Anyone have a good way of testing the dig inputs? Using maybe front pot on controller and shorting the for Rev to see if it will switch properly?

Well I have come to the conclusion that I may have a bad vfd.

No matter what I do, and verified all the settings, I can't get the input switches to work. No forward, no rev, even though u have checked and verified continuity at the terminals, but somehow the system isn't getting my commands.

Maybe time for a different vfd...though this one has zero hours

Any suggestions on a replacement vfd for 3hp motor?

The way I see it is that the only advantage is that you only need a shielded cable with two wires and through those two wires you have full control of your VFD. If you control via PWM then you need more, in my case four because I don't run the spindle reverse/forward, just one direction. Of course, through those wires I don't have full control of the VFD, just run/stop and the speed. The disadvantage of RS485 is that it is communication, and in the worst case you can lose contact with the computer or the VFD and in that case I have no idea what happens with your VFD, does it stop automatically or just continue spinning the motor until you manually hit the stop button?

Have a look at this one:

Bosch Rexroth Electric Drives and Controls

I have a 1.5kW version and it is just excellent. With all the problems I have read about the eBay VFDs and the fact that this is really not that expensive I decided to buy it. The documentation is excellent, over 400 pages manual plus a quick setup guide. It is easy to set up and configure with the help of a few pages, at least if you are only interested in basic setup, but tuning for your specific needs is also very easy. There is a free software and the VFD can fully be controlled through USB from any PC. Of course, you still have the RS485 possibility as well, and also the regular inputs/outputs.

Have a look at these three video I made so far about it if you are interested.

I will also make one about setting it up in SVC mode later on but will not have much time the next coming weeks to play with it. Have already tested in SVC mode as well but have not made any video about it.

I see a lot of people talking about Hitachi and Mitsubishi across the forums. I've also seen posts about abb.

How are these as well?

Hmm. Take a look at my terminal labeling....notice one row upside down?

I'm hoping this is due to Chinese wages and someone not giving an f!!

Going to try wiring according to everyone else's vfd on Google because so far, mine is only one produced with for and Rev towards the left instead of right.

Your top row of terminals are backwards.!!

The disadvantage of RS485 is that it is communication, and in the worst case you can lose contact with the computer or the VFD and in that case I have no idea what happens with your VFD, does it stop automatically or just continue spinning the motor until you manually hit the stop button?

With the Modbus plug in the communication is being constantly verified and e_stops in the case of error.

Well good news...flipped the sticker and bam...it worked....

Bad news...is bam...smoke out of the spindle.

I followed a post on here for settings and thinking something wasn't right. Maybe the 4 pole?
