Irregular Spindle Speed

[HipoPapi]

Hi There Jazz,

I had to take yesterday off but managed to take some better quality pictures today.

I have attached some and hope they are useful but if you need any specific pictures including screenshots from Mach3 please let me know as it seems will have to sort the problem our self's. All the Chinese support does is trying to push us to install nc studio instead of mach3 saying that the guy who built our machine and had mach3 experience has left their workplace.

Thanks again and have a good evening.

Ok well first need to know if your using Single phase 220V supply.?

If so then I'm quite confident that your problem is the new replacement spindle is designed ONLY for 380v.
The VFD while converts Single phase to Three phase it does not convert 220v to 380v.

The columbo Spindle was dual voltage, hence Delta or Star wiring options but the New replacement spindle, looking at the pic you posted doesn't and only works with 380v.

Confirm this and if using 380V then I'll continue and tell you which wires to check.

Just a quicky for Jazz - I know where you're coming from with the plate on the spindle, but googling the part number throws up bugger all info on aliexpress, but it does suggest that it can be wired star or delta, and a 6-pin connector on the spindle brings out each winding separately, and that the coil voltage is 220/380.

OP - Might be worth posting a photo of the electrical connector on the spindle.

IME if Spindles or motors can be wired both 220/380v the plate will state it. ie like the Coloumbo does. In this case can only go off what the plate says.
But it wouldn't hurt to have pic of the terminals for clarity.

Also if Ali express shows bugger all info how can it suggest Star -Delta.?

Various adverts give nothing like the amount of technical detail that I'd like, however, most, do clearly state the two voltage options, and a close-up of the 6 pin connector.

no data sheet so it could be available in both

[JAZZCNC]

They show 2 different PDF. One for the 220v another for 380V which suggests it's not dual voltage which is changable via usual methods. Also there is no Star Delta connection on the connector which also backs this up.

I'm keeping out of this one on the grounds that I have had a drink
