Hello raasco_alan and CJG71,

I've just discovered your thread and I am dealing with a similar problem. I have the KG-4925 and a building power flux scrambled some of the programs and vfd. I'm...

Sorry, when I tried to post this attachment it had errors and would not attach.

I think it will work now.

Thanks,
Robert

Hello,

I've been working on several problems with my K2cnc and I was wondering if any of you use the Delta VFD-B with your K2cnc?
I've lost the original settings for the VFD and was hoping...

Hello all again,

I've had to put this repair project on hold but now I can put some more time into it. I've discovered that the VFD had a blown fuse that is under a circuit board and only...

Hi Russ,

Is there a different way to send the troubleshooting guide? Maybe it's listed for downloading on a site?

I'm currently trying to find someone on campus who can help verify that the VFD...

Thanks for all the help Russ.

I will see if anyone has a motor I can use to test.

Robert

F stays at 60
H goes to 60 when jogged.
U stays at 0.00
A stays at 0.0

Changed setting:
When I hold "jog" it says 60.00 but no movement.

Russ,

I still have VDC at AUI and it changes when I change the speed.

I will look around to see if I have a 3ph motor.

Robert

Russ,

No luck. The command was issued but the frequency did not change from 0. I tried "run" and "jog" and all the arrows.

Robert

Hi Russ,

I've had some time to look over the manual and perform the trail run. I'm still having problems not being able to adjust the F number from the pad. I can jog over to any of the...

Russ,

Thanks for all the time you have put in to this! I've entered the new values to the excel sheet and also added a column to indicate if an error showed up as well. Please see attached.
I...

F= 0.00
H=0.00
U=0.00
A=0.0
-Frd-

Russ,

I'm still getting an error with 00-01-11.

Robert

Russ,

The Up/down arrows will not let me change the frequency number. It stays set at 0. When I hit and hold the jog button it shows 6.00.

Robert

Russ,

Nothing happened.

Robert

Yes, it did populate.

Russ,

I reset the VFD and know the Display reads "F, H, U, A" = 0
But I'm still getting -err- in 00-01 and I did not notice but also in 00-06

Robert

Russ,

Yes, I think we might have had a mini building power outage. During the week before I noticed the problems the lights in the building keep going on and off. The City is doing work down the...

Russ,

Quick question, when the pr is READ ONLY does it matter what number is seen or should it be set to 00? All of my READ ONLY have number values. Also, 00-05 is set to 60.00 not 1.

Robert

Russ, this is what I have for the VFD on start up.
"F, stop, and FWD" lit.
readings:
"F" = 300
"H" = 0.0
"U" = 18000
"HU" = 0.0
-Frd-

Robert

Yes, it rotates freely.

Russ,

The first part I'm sure I did correctly but I'm not sure about the second part.
U to V =.6 ohms
U to W =.6 ohms
V to W =.6 ohms

U to Ground = OL
V to Ground = OL
W to Ground = OL

Russ,

I changed all the programing twice and still no spindle power. Everything is like you said to start, I can change the "F" number up and down hit run and no power to the spindle.
Thanks for...

Russ,

Also, in the user manual it show a screen display for current, shown with an "A" in the screen. I do not know how to display this screen. When I run through the "mode" options it never...

Hi Russ,

OK, I set the VFD to the new settings but I will need your help in how to run the VFD. Also, what number should I be seening on the PU01 display? They seem off to me.
In the stop...

Yes, it was running shortly before everything started to go haywire.

Russ,

Yes, stuff happens but I'm not sure what I should be paying attention to.
Example, in the 'H" display it starts at 0.00 and when spindle is activated this number goes up to about 4000 give...

Russ,
No luck with the new settings.
Robert

Hi Russ,
Sorry I stepped away.
See attached for HSD spindle info.
