HUANGYANG VFD HY01-D523B only Power led in display

[strobel]

Hi ,

Was just cutting out some wingparts for my Klemm 25L.

Had to change material for the next cut.
Suddenly my HUANGYANG VFD HY01-D523B won´t start up the spindle.
Really strange since it has been working for some years now and no changes have been made as fx. wirering ect.ect.

Spindle is a RattMotor 0.8 KW 220 Volt (GDZ-65f-800)
VFD is HUANGYANG HY01-D523B

The power led in display lights up, fan is starting and that´s about it.
I´ve disabled the whole VFD to check:
- capacitors - OK
- Cable to the key pad (even from main board)- OK

I really don´t know what else to check

Is there anybody out there that can give me a clue or maybe have hade same issue and have a solution???

Keep my fingers crossed that some one can reply :-)

Thanks in advance

Have you just had it plugged in, or is it wired into the control, how have you been turning the main Power On / Off do you have a Ground / Earth connected

Try the VFD on another motor like a 3 phase one to see if it is the spindle and not the VFD.

Hi again :-)

Thank you all for your help!

But it seems that I've managed to solve the issue (for now :-) )

When I made my final check of the circuitboards I notised a cold joint on one of the boards.
I resoldered that joint but without the result I wanted :-).

So I resoldered ALL soldering point on the boards and - voilà! The VFD works again :-)

The only negative thing is that I already orderd a new VFD :-(, well at least I will have spareparts if needed :-)

Take care out there and stay healthy!!!

Best regards to you all

Good you where able to fix it, most that have not burnt up the boards can be fixed

I have done the same on a few of these that had not been burnt up, it can sometimes be the smallest connection that is not soldered well
