I recently tried the hy inverter....it didn't last long. My recommendation is that if you are using it to make money...get a better one. I do alot of 3d milling of mdf for boat and custom car applications and I think the 3d roughing programs are a little much for that drive. I have recently moved on to a hitachi 2.2kw drive with the nice chinese spindle from ugra cnc and its seems much better. I am keeping the chinese spindle as a spare but I won't buy another hy. That's my 2 cents worth on that.
I have questions about the hitachi drive. There seems to be many optional safety features. I have the drive running the spindle and ran the bearings in today. Does anyone have any advice on what features of the drive should I use to optimize it for a cnc mill/router?? I am assuming that the drive automatically works well for safety and running without going into all that but why not optimize?? The drive also has self tuning that I haven't tried yet. I'm using the drive with analog input. Any suggestions or general methods of using this or any vfd are appreciated. I am using a line reactor on the input side. I actually just smoked a hitachi drive also and just tuned in the replacement but the factory thinks the first drive was defective.....we'll see after they inspect it. I just want to do everything I can to make the system as reliable as possible....the roughing paths using longer tools to reach into cavities is definitely are the hardest on the machine and run for hours on end sometimes. Any suggestions?? Thank you.
After a 2 week pause my router 2.2kw HY VFD blows C10A fuses as soon as I energize the circuit. Checked hole setup for wire damage- all good. Nothing is changed. Is my cheap VFD dead now?
Has anyone experienced something similar?

First disconnect the spindle from the vfd and and see if it blows fuses without it connectedQuote:

Problem solved: brand new Huanyang Inverter with 1 year warranty.
Lessons learned: Do not buy VFD in the beginning of the build. I wasted my old units warranty that way :(
My beloved sparky fell off his perch. In our 40+ years of acquaintance I did not pay sufficient attention and now I am paying the price. - I can hear him laughing down at me, with his never to be forgotten sense of humor.
So I am prostrate requesting some assistance wiring a new 2.2 spindle.
Just need to check. At the spindle end I have wired the cable cap 1,2,3, E. The fixed terminals on the spindle I believe need to be opened from the 4 screws and the earth connection made, to the underside of one of those screws??
Shielding at that end is twisted into three strands and fed back out of the cable cap. - The other end of the shielding at the VFD end is then twisted and grounded?
Please help me get up from the prostrate position as the wife is getting annoyed about hoovering round me!
Have you checked to see the the 4th pin is connected to the case of the spindle (some are and some not).Quote:

I would rather do it this way than take the whole cap of the spindle
Personally I wouldn't connect the screen at the spindle end - it's for screening the cable, the no.4 (E) connection is for earthing the spindle casing. At the VFD end you twist the screen and the 4/E connection and join to the earth terminal.
Hi - Guys
Just setup the wiring for standard Huanyang 2 .2 spindle and VFD.
About to sort settings for VFD. Some info suggests not to power up the VFD without the spindle connected.
Which is correct please. With spindle connected or without.
really dont need to smoke anything at this stage!!
No need to have the motor connected. I usually only connect the motor once i have programmed the drive and tested the "settings". Most important thing is to make sure you have the motor connected properly
There is no problem with starting the VFD with the spindle disconnected .BUT don't ever disconnect the spindle with the VFD running.Quote:

Another thing to remember is to use the correct cable between the drive and motor. I just repaired a machine where the original builder used microphone cable (2.2 Kw Hy water cooled spindle)...besides the fact it's not rated for the voltage imagine the under size re current!!! If you can't confirm the voltage rating of the cable then just don't use it :)
Happened to document it....note also the soldering Attachment 26802
All up and running. Thank you gentlemen.
One more ask :- How do I connect the 12v water pump to the VFD please.
Hi Leadhead
These are the 2 options I thought about
1) Don't bother and have a separate connection for you water pump. Switch it on manually before starting the CNC/VFD. This is what I have done
2) Or operate it through the break-out board on your cnc controller using a relay. You would then issue some Gcode to start the pump before the spindle start Gcode
Hope this helps
Mike
No need to do either of those as it's very easy to let the VFD operate it.Quote:

The relay connections are FB & FC just feed either the positive or Negative of the power going to pump through these terminals.
Then change parameter for these relays to work when Fwd is pressed, I think the parameter is PD52 or 53 but not got the manual in front of me so I can not check.
The relay then just becomes a switch to the pump.
Hi Jazz
As always the font of wisdom for us newbies. I forgot about these ports on the VFD. I was thinking about these to enhance my safety system by getting the relay ( based on your wonderful simple design emergency stop setup) to signal the VFD to stop when the safety button switch is operated.
Cheers
Mike
I'm thinking of adding a slight enhancement to the "pump switched by VFD" thing by sticking a flow sensor in the return line to the reservoir driving a relay. It's then pretty easy to sound an alarm if the pump is energised but insufficient water's flowing.
Yep, that would work and there are various ways it can be done, to be honest. The controller or Bob your using will also play some part in which approach to use.Quote:

If going to that trouble I'd be more inclined to fit the temp sensor on the spindle than worry about water flow. Or have both work together.Quote:

Today I'm looking at a new Altivar 320 to replace it and I need help with setting it up Altivar 320 VFD + ESS Smoothstepper + Mach4 + Gecko G540
There is nothing wrong with the connector.Quote:

If the plug is not fitted correctly or is loose or a wire falls off the vfd will blow up. Always fit a cable strain clamp to the Z axis.
Never unplug the spindle or put any switch in thee cable from the vfd when the vfd in on.
+1 on what Clive has to say.
Happened to me recently - I was using a cable clamp so it had me scratching my head for a bit - turned out I had an oversized blob of solder on one of my pins that shorted against the inside of the connector's sleeve. Was purely luck that it hadn't done that before - I'd recently moved my machine into a new workspace and had to unplug and re-assemble everything - something moved and I wasn't as lucky this time around... Made quite a pop!
Wal.
You are correct, some suppliers supply undersized/under rated connectors. Full load current of a three phase motor is not split between phases. However your spindle might never draw the full load current. But if your motor is rated for say 10A that means ten amps per phase and you should have a cable and plug that is rated minimum 10A...:)Quote:

A good reason for putting Hellerman or heat-shrink sleeving over each pin/wire.Quote:

I've only ever had 3 fails with connector faults and all of them where because the cable restraint I'd fitted had been left unconnected after the customer had moved or adjusted spindle etc and not fastened cables back up.
It's common sense really. . . which isn't so common these days.!
Oh yes, yes, yes, yes!!!!Quote:

I'm not sure that the connectors are capable of even taking a cable that is nominally rated for 10A.
In practice, in the amateur machines where these spindles are typically used, I doubt that they often are used for continuous currents like this. Attention to proper cable management and avoiding flex in the connectors is probably a bigger issue. My own spindle and HY VFD are now in use in a second router and are about 7 years old, still going strong. In fact, outlived the PC and monitor that drive the machine, both of which have needed replacement in that time...
Attachment 27012
The connector on the left is a GX16, the one on the right is a spindle connector.
Internally they are a bit different, the spindle connector is a much higher current and voltage rating.
Attachment 27013
You can plug the GX16 into a spindle, but it is a sloppy fit and not a good connection.
Well, you'd be wrong but your reply tells me you have little to no experience of these Spindles.! . . . However, Lets put this to the test because I know lots of folks on this Forum have these spindles and see how many on this forum have had issues with loads and pins/connector.?Quote:

I use a bunch of GX16 (at least, that's what the Aliexpress seller called them!) for signal connections on my control box and never actually put one alongside the spindle connector to look at the difference. Just assumed that they were the same as they are superficially very similar. So much for assumptions! Surprised if they had a much higher current rating as the pin/socket size must be very similar but I guess that it's all down to how well they fit, spring mechanism, etc. Thanks for the correction, Rob - if I ever need to replace my spindle connector I'll make sure I get the right thing!Quote:

They are useful connectors though, but probably a bit too lightweight to chew mains voltages, but OK for small steppers and signals.

>because pins touched due to poor soldering
Hehe. Dean, the soldering was good, it's just that there was too much of good soldering..! ;)

Not the first wal, won't be the last and it's all good learning, expensive but good..:yahoo:Quote:

They have a voltage rating of 400V RMS in a 4 pole according to the Renhotec catalogue, so ought to be OK for most of the time. The only issue once in a blue moon might be spikes due to ringing as a consequence of poor cable, long cable runs etc. increasing the peak voltage.Quote:
