Hi, i have bought the spindle recently,, but, uh i have no idea how to wire it up,, can anyone lead me to the something that can give me the idea to wire it?
Here some pictures.
Thanks

You are in luck.

This looks like standard HSD pinout/connectors.

This
should help.

Assuming the connectors look like the picture you have i would just buy the HSD premade cables. They are proper flex cable.
The only things to keep in mind:
If the fan is 230v great, they work out great (the power cable is 4x10awg + 2x22awg, and the 2x22awg power the fan).
If the fan is 24v, it is a little annoying of a configuration because usually your 24v supply is near the signals, not the VFD.

I haven't seen multiple configurations of the premade cables to account for this, but they may exist!
They also don't have the encoder pins connected.

You can also just buy a wiring kit that has the right connectors, crimp pins, etc. I don't know the connector models offhand.

I will say, the 4x10awg + 2x22awg HSD uses for power cable is not easily findable. If you go your own, you'd have to run two cables or something if you want do what they do for power.
The signal cable is very standard.
If you go this route, igus.com is your friend for flex cable.

Also, if you want to understand how the circuits work, i've never done a centroid PLC versions, but i'm happy to send you PLC code that you can use as a reference for how to implement the release/lock/etc circuits properly.
I've done it for automationdirect BRX's, as well as beckhoff twincat.

Honestly, it's pretty straightforward.

One final thing to note: At least on the HSD (and hiteco), the S3 sensor works from 0 to max rpm, so gives you a simple 2 pulse per revolution encoder.
Any fast enough high speed counter input can count them properly. This lets you do nice things like know when the spindle is at the commanded speed, etc. It's obviously not enough to do tapping or anything, but still nice.

They may or may not have cheaped out on your chinese spindle. Theoretically, S3 only needs to tell you whether the shaft is spinning at all.

Plus one on using the HSD cables. Pricey, but may be cheaper in the long run (magic smoke)

I have install a couple dozen of the HSD ATC spindles and was never able to get a reliable signal from the S3 sensor. I think the reason is that there are 3 states. 1) spinning with pulses 2) stopped with no signal 3) stopped with signal on. Since the majority of inputs are binary (0, 1) you can get a false positive if the spindle happens to stop on one of the 2 pulse locations.

I usually use VFD outputs set to: 1) "zero speed" and 2) "at speed" to eliminate any programmed time dwell time during tool changes.

How about some out of the box pics and pricing. Chinese plywood does not satisfy the tool junkie in me.

Ok note, thanks Danny B, thanks Garry Camble,, for the reply,, appreciate it,,

Interesting. I've only installed about 12, but had good luck.
But I use counters that count the full pulses (not just the edges), so stopping on the pulse generation location will not do anything (since there will be no falling edge after). If you use a thing that is just polling the state really fast instead of actually having some state machine that requires changes, this will not work, as you say.

The automationdirect BRX PLC nicely allows you to choose between any of the options (count any edge, count trailing edge, count leading edge, count pulse).

Using VFD's idea of current speed works in a pinch, as you say.

Garry camble,, here some more photo an outside the box, price and recommended driver to use,,

The thing they are recommending is what are known as spindle drives. They are special purpose servo drives meant for spindles. You don't really need one unless you are trying to do something complex or can't find an 800hz regular vfd. They are often expensive and trickier to install.

Two problems based on these pictures:

1. You need 380v 3-phase. If you have 460v 3-phase, this is no issue.
If you only have 220v single phase, you have a problem.
Unless this thing is dual voltage and can be switched from 380 to 220v, that will be a pain.
You would need some 3-phase converter and then a step-up voltage transformer.
I have also seen 220 single phase -> 380v 3 phase inverters on ebay and aliexpress, but honestly i wouldn't touch that with a 30 ft pole.

2. It requires 800hz at max speed because it's a 4 pole motor. That is also a pain in the ass these days. It is hard to find VFD's that will do > 600hz now, and doing so usually requires bugging sales people to convince them they do in fact sell such a thing and then signing fun papers. The TL;DR is that they were being used for nuclear centrifuges, so almost all companies limit to 600hz the past few years (If you find models marked otherwise, *DOUBLE CHECK*. For example, schneider used to sell an Altivar series that did 1600hz, but it is now software limited to 600hz. Places still list them as 1600hz and they won't do it).
A few offer specialized firmware/models to do higher speed if you sign papers promising not to export it (and seriously, you don't want to f*ck around with that).
The two i know of that you could get without a real hassle would be Delta's MS300 high speed version, and KEB's F6/F6-K.

Delta's is fairly cheap (O(1000) bucks), KEB is more featureful but expensive (O(2500) bucks).

Now, you could also stay at 600hz - like i said, plenty of VFD's that will do this. For example, automationdirect's gs4 line (i haven't looked at the gs2/gs3).

This would limit your max speed to 18000rpm. Unless you are using really small bits, you probably don't want to be going 24krpm anyway, as it's suboptimal for tool life for say, most 1/4 or 1/2 inch bits in wood.

I was wondering when the 380V was going to be brought up

dear Danny B
what it mean pin no 3 and n0 9,, is that to provide two hot wire? or what?
