The 2.2Kw Chinese Spindles - Info, Setup and Advice + More

[toomast]

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 :(

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!!

There is no problem with starting the VFD with the spindle disconnected .BUT don't ever disconnect the spindle with the VFD running.

Always make sure you fasten (clamp) the spindle cable to a fixed point so that the plug does not move, as a bad connection in the plug or a spark WILL give you a fright and release some money from your wallet

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

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

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

No need to do either of those as it's very easy to let the VFD operate it.

There is relay built into the VFD which can be set up to turn on/off when spindle spins. By default it's set to operate when a fault occurs but with few parameter changes can be set
for on/off.

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.
