I am having a little trouble getting my spindle to start moving with my Huanyang GT series VFD and I just get an OC1 overcurrent protection error when I press Run. I was hoping that someone who is familiar with these units could point me in the right direction...

I got this unit a year ago and at the time, I input all the parameters and went through the set-up / auto tune process. It seemed to work as intended. The spindle was spinning during the auto tune and it completed the process as described in the book. Then I put my my CNC project on hold for a year. I tried turning it on today but I can't get any movement.

The VFD turns on ok with no error messages but when I turn the potentiometer the "trip" light comes on immediately with the "OC1" error.

First, how long do these units store settings? I.e. Do I need to factory reset, restart everything and go through the auto tune again? Or do the settings stay saved once the initial install process is complete?

What else should I check to see why it is not working and is there anything I can try to prevent the overload fault?

I'm not sure if it matters for this question but just in case, It is a 7.5kw GT series rated for 220v 1ph in, 3ph out. The circuit is 60 amp and the spindle is a 5.5kw 220v 3ph 19a 400hz / 24000 rpm 2 pole.

Parameters don't normally change once set

Check P0.11=10 start at 10sec and adjust down until you get a fault then take it up above where the fault is

You also may need to set P00.00=0 as it may be producing to much torque on startup with being set at ( 1 )

Check the incoming voltage this 7.5Kw is right at the max for single phase supply

I tried adjusting the start up time to 10 and then 14. It still OC1 trips. Should I try higher or should I assume that, if 14 still trips, then the issue is something else?

How do I check if 7.5kw is the incoming voltage? The spindle is 5.6kw at 24,000 rpm but I can't get it to even start moving. It trips at 0 rpm where the draw should be far less than 5.6kw. The circuit tester i have only confirms 220v. It has no options to check kw at the spindle or VFD. What device do you use?

I'll check P00.00 again. I think it might already be set to 0.

Is there anything else I can try? There seems to some settings related to overload protection but I assumed I was not meant to mess with those...

Is your spindle water cooled or air cooled

Is your spindle water cooled or air cooled

It is electric fan cooled. It uses a seperate 24v PSU.

It is electric fan cooled. It uses a seperate 24v PSU.

Check that all your parameters are set correct

These are what you need set
Mactec54
400Hz 220v 5.5Kw Water Cooled Spindle Settings

P0.00=0 ( 0 for V/ F Control 1 For Vector Control )

P0.01=0 ( 0 For KeyPad 1 For Remote Terminal Use )

P0.02=3

P0.03=400

P0.04=400

P0.05=120 ( you may be able to go lower depending on Spindle Temperature 100 Minimum )

P0.06=400

P0.11=8 ( adjustable Acceleration )

P0.12=8 ( adjustable Deceleration )

P0.14= 6 ( 6 to 8 )

P0.17= ( 1 to Restore Factory Defaults ) ( 2 clears all Faults )

P1.01=10


P2.01=5.5 ( Motor Settings )

P2.02=400

P2.03=24000

P2.04=220

P2.05=19.5

P7.14=7.5 ( VFD Rated KW )

P7.15= ?? ( VFD Rated output Amps )

Once these Parameters are set, you can then do a Autotune, you set Parameter P016=1 and Press Run, ( The Spindle Must Be Clear To Run )

For main wiring connect R Hot T Hot wires and Ground to the Ground Terminal, this is your connection for NA 240v single Phase

Is the spindle Ground wire connected ???
