hey just putting the last bits of kit together for my new 4x4 mk2. so i have the spindle and vfd from huanyang. i perused the support forums here for a bit. decided to order a couple of pwm converters (yes two, i like spares) wondering if there is anything else i need to look into. i do ok with parameters and such. programing the drive should not be much of a problem i shouldnt think. ive done much bigger drives than this lil doodad. guess im asking more about the connections to the slb and any firmware changes i need to make. oh. its a 2.2 water cooled version.
You shouldn’t need the pwm converters. The Huanyang will connect with the RS485 without them.
I am using the Huanyang VFD and 2.2KW water cooled spindle and love it! 4x4 Altmill Mk2.
I must admit I too purchased a converter just in case I couldn’t get the RS485 to work.

I have helped with setting up those vfds on the FB group. Why pwm instead of RS-485?
For RS485 you should only need to set the address pd163 (any number i used 2) , Baud pd164 (I use 192000 param value of 2. And data method pd165 to 3.
This jumper needs to be switched to as shown
These are the rs485 pins
Set the default spindle in gsender to huanyang v1 and match the address and baud. If forward on the spindle tab doesn’t spin up the spindle swap the cables on the 485 terminals.
from the posts i had read on here i somehow was under the impression that i needed them because the pwm was running at 5v and the drive needed 0/10. 10 being wot.
This was the only way to get spindle control on the original longboard controller. I never could get that to work. RS485 support is one of the reasons I upgraded to a SLB.
Hey Courtney,
As far as I can see, Kerryh is right. If you have an SLB, you are good to use RS485 if your VFD has that option.
When using PWM output, you need to convert, if the VFD does not take 5V PWM, as stated here:
Found here:
ok. i blew up one drive. have no clue what happened in detail. i checked the cable and connector to spindle with my meter. nothing is shorted and #4 pin is ground as it should be.  uwv went to the corresponding terminals.  drive powered up but when i sent a speed command via the speed pot on the drive she popped something on the inside and never was heard from again. i had the jumper set for using the speed pot just for testing purposes. no other connections other than incoming power (120v to the first and third terminals) the listing on amazon states its a 110v system so i assumed that since the drive powered up with line on the first terminal and nuetral on the third everything was fine.  (it was not fine) now the question.
can you send me a detailed picture of exactly how you hooked yours up?  and if you have time the parameters you changed from the manufacturer?
i should also add that this is an HY series of drive from haunyang. 110v 2.2kw water cooled spindle. 400hz
ok. its an hy series drive. 110v 2.2kw. did you hook up pin 4 on the spindle to the earth ground terminal on the drive? as in the one with the red paint on it?
Pin 4 on the spindle should not be connected to anything internally (at least mine is not). I used that wire to ground the shielding. in the motor feed cable.
I let much smoke out of my first spindle and vfd by changing a parameter I shouldn’t have. I can’t remember which one, just that it had to do with voltage. On the replacement, I only would touch frequency and RS485 related params.
thanks. im starting to believe that wire being hooked up to the earth ground terminal next to the uvw terminals is what popped the drive.
followed the unofficial set up guide for the hy series drive. set up the rs485 parameters.
sent a m3s18000 command via the console and get a spindle not at speed fault. is there a feedback setting im missing? or something else.
Does the spindle start to spin?
If you can still turn on the spindle and control the speed from the panel on the vfd, there is a jumper on the right side of the terminal block that needs to be switched.
If not, try swapping the wires on the RS485 terminals. Serial connections have a crossover.
no movement from the spindle and the error 14 is instant. will go check if swapping the terminals helps.
yes i have the jumper on the left two pins (VI) will let you know in a few
also, make sure to power the vfd before the SLB
SPINDLE GO SPINNY!!! thank you soooo much. that is enough for me tonight. will learn some more tomorrow morning.
Happy to help, have fun.
