Chinese spindle questions
Hi folks,
Relative noob to CNC here, after 20 yrs. of manual woodworking/machining.
I have a kit machine (Routakit...beware!) with a generic Chinese spindle/VFD combo.
It's the square bodied 1.6kw air cooled unit that can be found on eBay and elsewhere.
Anyway - I hooked it up and programmed according to the (poor) instructions from Routakit,
and the spindle only gets to 12k, half of the 24k it should be reaching at full speed.
I have been through reprogramming the VFD several times but nothing seems to do it.
Can anyone walk me through diagnosing this thing?
My first guess was the motor pole parameter (2 vs. 4) but I am programming it according to recommended settings.
Also, the spindle spins backwards. Assuming I can just switch any two legs on the VFD output to fix that?
(I have been just pressing the "Rev" switch on the drive to make it run, but that's annoying.)
Many thanks in advance!

Re: Chinese spindle questions
Yes that is a sure way to fry your spindle, need to know your spindle specs, don't run it until we have this sorted out with the correct Parameters set
Air Cooled or water Cooled ????
Kw=
Voltage220 ???
Hz=400 ???
Amps= spindle rated amps

Hi Mactec54,
Thanks again for your reply.
I have been running the spindle thus far with the parameters above.
I just tried setting it up as per a post of yours I found from 2017 (below).
However, I am getting A.OL errors as it tries to come up to speed.
Regarding the questions above:
Voltage - the VFD plugs into a 120v outlet. Not 100% what voltage the spindle expects to see (?)
Air Cooled spindle
Hz - 400 I believe
Amps: the spindle is a 1.5kw so I'm assuming 7 amps as per your post below.
Pretty sure this is just the basic/generic Huanyang type spindle/VFD combo.
It was supplied by the people that sold my machine kit, but they will not provide tech support.
I need to mill some slots with a .022" cutter so I really need to turn up the RPM as high as possible.
Thank you!

Parameters copied from your older post:
PD000=0 for Parameter unlock ( 1 ) for Parameter Lock
PD001=0 (1 For Remote Control)
PD002=0 ( 1 For 0-10v Terminal Control or Remote Trim Pot Control )
( J1 Also Needs to be set for Terminal Control )

PD007=20
PD008=220 (120 If you have 120v VFD )
PD009=15
PD010=8
PD011=120 ( 100 Minimum Setting with Quality VFD, 120 is Safe)
PD13= 08 is for Factory reset, Only use this to set VFD to Factory Default Settings
PD014 Acceleration=12 ( Adjust to suit)
PD015 Deceleration=12 (Adjust to suit)
( PD15 is ignored IF PD26=1 Then the Spindle will Coast to a Stop)
PD141=220 ( Motor Rated Voltage ) (120 for VFD Rated for 120v )
PD142= ( Motor Max Amps)
PD142=( 220vSet for your motor Amp Rating 2.2Kw Spindle 9 amp )

PD73=120 ( 100 Minimum Setting )
Re: Chinese spindle questions
Yes that was from a long time ago a little confusing so I never posted them like that again
They are almost the same as what you had except
For these 4 Parameters which 3 of them you need for your Spindle
PD003=400
PD004=400
PD005=400
PD007=0.5 Change this for your 120V spindle
Your Amps may have been set to high also
PD142=7 max 8 you had 11 before
What do you have
PD014=???
PD015=???

Re: Chinese spindle questions
All are set as above - my PD007 was originally 0.5, I changed to 20 per your old post but it's changed back to 0.5
PD014 and PD015 are both set to 5 at the moment.
When I turn on the VFD, it starts around 300 and spins for a few seconds. Then it spins up to about 450 for a couple of seconds and starts throwing A.oL codes.
The codes continue flashing on the VFD for a bit after I turn off the spindle.
Potentially helpful (?) diagnostic info:
When I originally set it up, I had wired the spindle so it ran backwards. Rather than swapping two of the wires to make it run forward, I just pushed the Rev switch on the VFD before turning it on.
(Yes, I'm a bit lazy!)
The spindle spun up with no ramp-up time - straight to full speed. But it did so without overloading, and ran fine.
I have run it like for operations as long as 45 minutes without incident.
I finally got around to pulling off the VFD cover and switching two wires to make it run forward. Could I have made a mistake with switching the wrong two?
(In the past, I've swapped any two wires of a 3-phase motor to reverse the direction. The wire swap did accomplish the direction change I wanted here.)
Also, in case it's useful, here's the info from my VFD nameplate:
Model: HY1D511B
3PHAC110 +/- 20% 50hz +/-5hz
3 PH 0-110AC 1.5KW 13A 0.50 - 400.00Hz
Looking at it, I'm a bit concerned that it seems the input is meant to be 3 phase (first line)?
My input is 120v 60hz single-phase.
Could they have sent me the wrong VFD?
Thanks for all your help!
Best wishes,
Martin
Looking through the manuals, I'm wondering if my problem isn't the PD006 - PD010 values.
Here's my reasoning:
The error code I'm getting is EolA, which manual describes as follows:
"Inverter Overload 150% per minute"
The three suggested causes are:
1: Inverter capacity may be too low
2: Jamming in mechanical load (not the case here)
3: "Setting of the V/F curve is bad"
Searching for the term "V/F curve", I come across this in the manual for PD010:
"This parameter is set for the min. starting voltage of V/F curve.
The factory setting of min. voltage for 220V class inverters is 8, and the factory setting of min.
voltage for 380V class inverters is 13.5.
This set value is limited by the voltage at the max. Frequency."
Now, mine is a 110v inverter according to the faceplate. If this setting scales down with voltage as the above suggests, then maybe mine should be lower for the 110v unit? Maintaining the proportions between these two sets of numbers would suggest a PD010 setting of 4 for the 110v unit....?
Or is the VFD putting out 220v to my spindle, in which case these numbers should be at the 220v levels?
I just don't know enough here.
Also, there's this from the PD009 manual page:
"This parameter is set for an intermediate voltage value of arbitrary V/Fc urve.I f it is set im properly,
it will cause over-current or under-torque of the motor, or even tripping of the inverter.
When the intermediate frequency is increased the voltage will increase the output torque and at the
same time also the output current. When changing this parameter please pay attention to monitorin g
the output current to avoid the inverter's tripping due to over-current.
The factory setting of intermediate voltage for 220V class inverter is 15, while the factory setting
of intermediate voltage of 380V class inverter is 27.5."
Again, by the same logic, for a 110v should be somewhere around 7.5 if it is to maintain the same ratio as the 220/15 and 380/27.5.
Am I doing this wrong? At this point I have jobs waiting on this little machine and I'm dead in the water.
Hoping someone can help!!
Thanks,
Martin
