Hi,

I am building my first 4 Axis CNC Router, project is almost done and working on wiring the 2.2 KW Spindle with a Huanyang VFD.
I am a little confused on wiring the R S T input to the VFD.
I live in the U.S.
I am wiring the input with 220 VAC. Three wires. 1 - 120 VAC; 1 - 120 VAC and one Ground wire.
i searched the internet, most what I found is 2 wire connection. Hot wire to R and T to ground.

I don't want to fry anything up and just wondering if somebody can help me.
How should I wire the input?
R - 120 VAC?
S - 120 VAC?
T - Ground?

Thank you in advance for any help!

Do not wire the ground to the T terminal. There should be a separate ground terminal, possibly labeled E? On the Ebay auction I looked at, it looks like ground is 9?

R and S sounds correct, but I don't have one of these to say 100%.

The input is a 3phase rectifier so connecting the 240v L1 & L2 to any R,S or T pair will work, do NOT connect the GND to anything but the E terminal.
As the Manual says "R.S.T input current if the single-phase source meets two willfully"?
If you understand that 'Chinglish' let me know!
I used R & S.
Make sure the ground conductor also goes to the motor frame.
The manual is online if you don't have it.

Al,

Thank you for your help.
I will connect the 2 hot wires to R & S and ground wire to ground on VFD.

Ger21,

Thank you for your help.
I took a picture of the VFD terminals.
like you and Al said. I will connect R & S (Hot).
and Terminal 9 to ground.

You also have to set the Parameters correct, here is what you will need to use to get it safely running, failing to set the Parameters correct will Damage the Drive

Huanyang Mactec54
PD000=0 for Parameter unlock ( 1 ) for Parameter Lock

PD001=0 (1 For Remote Control)

PD002=0

PD003=400

PD004=400

PD005=400

PD007=20

PD008=220

PD011=120 (Minimum Setting 120)

PD009=15

PD010=8

PD13= 08 is for Factory reset, Only use this to set VFD to Factory Default Settings

PD014 Accel=12 ( Adjust to suit)

PD015 Deccl=12 (Adjust to suit) ( PD15 is ignored IF PD26=1 Then the Spindle will Coast to a Stop)

PD141=220 ( Motor Rated Voltage )

PD142=9 ( Motor Max Amps) (Set for your motor Amp Rating 2.2Kw Spindle 9 amp Max)
(Set for your motor Amp Rating 1.5Kw Spindle 7 amp Max)

PD143=2 ( Motor Number of Poles)

PD144=3000 (Max Motor RPM) =3,000= (24,000)

PD142 = 11.0
PD144 = 1440 ( less than 2500)

There is also a neat Huanyang Modbus plug in control if using Mach.

Mactec54,

Thank you.
This will help me a lot.

Hi,

Thank you for the information.
First time I've seen the first video.
I have seen the second one..

Al,

Thanks again.
I am using the demo version of Mach 3 and will be buying the license for it this coming week.
This will be the first time I will be using Mach 3 and also the first time I built a CNC router.
Still learning.
Kinda slow, I work full time and just work on the CNC router a couple of hours at night.

I have Mach 3 working on my CNC Router and now working on the spindle wiring and configuring the Autozero set.
My auto zero works but have a little bug on it. Still playing with it.
I have copied several script to edit the auto zero button but non of them works perfect. there's some fine tuning to do.

You mentioned something about Modbus Mach 3 Plug in for Huanyang.
Can you elaborate more on this? What does this do?

Here's a shot of the CNC Router where I am so far. I still have to install the T slots on top of the table.

Thank you for your help again and also thanks again for everybody who help me on this thread.

There is a link in my last post to the author and also on the Mach forum there is an extensive thread, If I can find it I will post it.
It uses a three-wire serial or USB/serial converter to communicate with the VFD.

The numbers you have posted are incorrect

PD142=11 is an incorrect setting, for this motor Max Amps

PD144 incorrect setting, needs to be set to 3000, for max spindle RPM

PD023=1 is the Factory Default, putting it in your list is only confusing for new users
