Fuling DZB200 Inverter

Hello,

I am looking for some help with a Fuling Inverter and Spindle that I have for my CNC Router, I have had the machine for a couple of years now (Chinese machine), when I first bought the machine it was fitted with a Makita palm router, the guy I bought the machine from removed the original Inverter and spindle to replace with the Makita. I was provided with the inverter & spindle when I bought the machine both of which still look brand new. The guy informed me that he couldn't get the spindle to function properly (personally I got the feeling he didn't really know what he was doing with programming the speeds etc this was originally all hooked up to ncstudio) therefore the spindle and inverter was removed.

I am now using the machine more and more and would like to expand the cutter range that I can utilise as the Makita only has a 1/4" collet which limits the type of tools I can buy.

To get me started I am quite happy to just control the spindle from the controls on the Inverter, I therefore connected the Inverter up to the mains and powered it up thinking I would just be able to press run and away we go, however nothing is ever this easy!! needless to say the spindle didn't run, hence this post.

I have gone through the settings in the Inverter and tweaked some that I could understand from the manual, I have also checked the spindle is free to rotate as well as all connections and wires for any damage which there doesn't appear to be any that I can see. I also noted down all the setting values prior to making any changes.

Attached is a photo of the spindle and display in question along with the manual and all the current setting values including the defaults.

Could someone assist in helping me to get this up and running please?

The inverter appears to power up ok

Kind regards

What have you changed. How do you have it wired. The spindle you have seems to be a 2 pole motor

In the manual I don't see a parameter to change the number of poles
From the manual:-

13. About Applicable Motor
1) The standard motor used is the 4-pole squirrel cage asynchronous induction motor. If other kind of
motor is used, please be sure to select the applicable inverter according to the rated current of the motor,
and please consult us if the user wants the inverter to drive the permanent magnetic synchronized motor.

Hi thanks for replying.

I have the 240v supply connected as follows:
Live - T connection
Neutral - R connection
Earth

The spindle is connected to U, V & W and also earth

A quick Google of GDZ-23 suggests it's a 3 phase motor which will therefore need a different inverter.

hmm strange, this was the original inverter/VFD and spindle that was delivered with the machine?

That dose not mean that they are correct but a lot of VFD's you can change the number of poles.

I would have thought that it should run but not correctly using 4 poles and therefore not be suitable with that spindle. Those spindles require 400 hz and standard motors run on 50 hz.

Yes all these spindles are 3 phase and that's why they a run with a VFD which changes single phase to 3 phase. The VFD is correct.

Dougie, these Fulling VFD's are a pain to setup, I had the same problem with the current machine I'm building and I've fit 100's.
To be honest I can't remember the settings but I do have the written down at work and will check them out for you on monday.

I will scan the manual today to see if it jogs my memory.

Thanks, I've attached a photograph of the nameplate from the inverter the manual was downloaded from another forum Attachment 28248

Thanks Jazzcnc, I was getting a bit confused by the previous guys replies as the inverter was still fitted and wired into the BOB in the machine when I took delivery, the pervious owners had only disconnected the spindle.

very much appreciated

Ok I've just looked at the manual and I remember the parameter that sorted my issues was F1.0 I can't remember what it's set too but this was the game changer parameter so try changing it to 0 or 1 and see what happens. I think you need to restart the VFD for changes to take affect.
