Chinese hsd spindle

[Rosmadi]

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.

pin no3 and pin no 9,, is that to provide two hot wire?

[DannyB]

On standard HSD spindles, pin 3/9 on the power connector are two 230v hots.
They provide power for the *fan* only, and *only* are connected if the fan is 230v.

If the fan is a 24v fan, they will not be connected.

They are unrelated to the power pins for the spindle itself (since it's 3 phase)

[Rosmadi]

Yes, the fan is 230v thanks for the advised,, and another thing is,, i bought a servo drive, dont know or not sure how to connect it,, afraid ,, my spindle has encoder on it,, where should I connect it, is it to the servo drive or to acorn board,

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 do run a 380V spindle on 220V using a VFD that uprates the voltage. This is single phase 220V input VFD.

[tblough]

And yet he has a 480V output VFD which will probably fry the 380V motor windings.

[Muzzer]

You can set up the VFD for a lower voltage machine easily enough. The winding insulation will be fine. Once it knows the nameplate voltage, current and base speed, it does the rest. Getting that wrong might result in saturating the stator but that's a risk no matter what motor voltage you are running.

It's unusual for low power 3-ph VFDs to check the presence of all 3 phases, so one simple solution would be to connect up a 240:120V single phase transformer as an autotransformer to step up the 240V to around 360Vac. Then operate the VFD on 2 of the three phase inputs, which is how most VFDs re connected up to single phase.

Hi guys, the problem i, where the connetion for the spindle encoder should i hook , to the servo driver or to the acorn board,, anyone has done it before?
And,Need some clarification from the expert,, which one should i connect spin foward and reverse to this pin from op4 and op5 at the acorn board,

[Rosmadi]

Need confirmation for this one,, spindle foward and spindle reverse,,which input should i connect,,

Connect the spindle-forward output to DI1.

It looks like your drive does not, by default, have an input defined for spindle-reverse. Therefore you will need to figure out from their manual how to change the function of one of its inputs (e.g. DI2) to be a reverse run command; or, if you don't actually have any need to run the spindle in reverse, you can just leave that output disconnected.
