Spindle ?

[Ms Wolffie]

When I eventually manage to get my spindle and inverter fitted, how do I determine the speed of the spindle?
I have a speed control knob on the inverter but how can I work out what is whatT?
I am not an electronics genius

While there may be cheaper ones found, this is a very handy tool for what I "think" you're after:

Hope that helps,

Is there a display on the front of the inverter? If there isn't a setting to directly display RPM's it should display the frequency and you should be able to calculate the RPM from there.

That means calculations and brain strain, YUK
Actually, I don't know how it works, I have to learn to read Chinese first

It's not the only one in the world, my friend

Wolffie,

If yours looks anything like this, it will display the rpm's.

I found a similar one in China that has no problem with shipping here, free delivery even, but neither Amazon nor any other one I found in the US will ship these to Australia.
I do not understand why?????

Yes, I believe that display will show the RPMs if I'm not mistaken.

If only I could get the thing to work
I connect power to the unit, it says "hello" continues to 00000 the something flashes on and it trips the circuitbreaker.
I have no idea what I have done wrong except that I cannot find the earth connection screw, so I bridged it to the spindle earth.

Spindles require a lot of power, I'm assuming a 2hp is 220v, 20A. Maybe the breaker is tripping because it is trying to draw more current on startup than your breaker allows.

No, the spindle is 220V, 8 amp.
The inverter even trips the breaker without the spindle connected.
The seller has just confirmed that there is no earth connecting screw in this model.
Where on earth/how do I connect the earth wire?

Pin 9 the one with the big E should be your earth. I have a attached a picture of mine with connection details as supplied. Remember that RST is the live in and UVW are the spindle connections.

I wish mine looked like that but it doesn't
