"Low voltage on bus" error - spindle or VFD problem?

[tazma]

hello I hope it helps you I have a problem I think that configuration vdf I do not know how to configure

hello I hope it helps you I have a problem I think that configuration vdf I do not know how to configure

What is your supply Voltage ???

Spindle rated Voltage= ???

[tazma]

Voltaje nominal del husillo 220 Voltios

[mactec54]

Voltaje nominal del husillo 220 Voltios

Here are 2 lots of Parameters see what your VFD Drive has and set which ever Parameters your VFD Drive has

Mactec54 1.5Kw
XSY-ATI 200X

P01=400

P05=100

P06=400

P07=100

P26=400

AT1-2200XSY

P00=220

P01=400

P03=15 ( adjust up to 25 )

P04=220

P05=100

P06=400

P07=100

P10=1 Default Potentiometer control ( 2 ) External Control

P011=0 Default Key Board Control ( 1 ) External Control

P025=0 2Pole

P034= 10 ( adjust Acceleration )

P042=10 ( adjust Deceleration )

P078= ??? ( Max Amp Overload set to suit your spindle )

P069= Over Voltage 220/240

thank you, thank you now I hope it works well

hello me testing parameters but it does not work, but it instantly jumps err 1

this model

Check your wiring especially the spindle plug it is saying you have a short circuit, or current overload


Check the spindle windings with a meter , post a photo of your wiring

Pin1 to Pin2

Pin2 to Pin3

Pin3 to Pin1

Pin4 to Earth /Ground ( Spindle Body )


Check these Parameters there may be some others these are slightly different from the other manual, there manual is not very good I have 3 different manuals for the same VFD Drive so very confusing VFD Drive, I would not recommend anyone to buy this VFD Drive

P00=220

well, it looks like I'm going from bad to worse, hehe but keep trying
for a future I buy another variator to recommend

this is what happens now



spindle connection & xsy-at1 I think well

You may be closer than you think change P069=240 that fault is over voltage you got rid of the Error 1 we will try some different thigs for the over voltage

Green wire PE should be connected to Pin 4 and back to the PE Earth Ground on the VFD Drive , are you using a shielded cable as this cable from the VFD to the spindle needs to be shielded

[tazma]

ok now I do not have shielded cable
Buy and test I hope it works
thanks for the help you are giving me

[mactec54]

Shielded cable has to have the shield Earth /Ground like this

No having the shielded cable is not the problem with your VFD lets see if we can get that VFD running buy changing parameters

[tazma]

I'm testing xsy-at1 disconnected from the spindle
It works well
connected spindl err 3
I hope today I can acquire protected cable

[mactec54]

The cable is not going to solve this problem we have to work with the VFD to get that working

Parameter P04=220

[tazma]

P004 = 220 does not let rise more than 220
P069 = 240 err3
I keep trying to see if there is luck

[mactec54]

P004 = 220 does not let rise more than 220
P069 = 240 err3
I keep trying to see if there is luck

220 is fine to try that is what your spindle is rated at others have not had this problem with this VFD Drive but it is not one that I would buy, it is very hard to know what is wrong with it


Do you have a good supply Voltage ????

P26=400
P27=400

P32=100

[tazma]

I do not understand what happens it's all very strange
P069 = 400 works fine but everything without spindle
but if P069 220 gives error 3 instantly

do not spindle


with spindle

[mactec54]

The VFD is also not displaying the correct output at full turn of the pot should be=400 so is not working correct

The VFD Drive is saying you have a short circuit

Either the wiring from the VFD to the Spindle

Or the Spindle is Faulty have you checked with a meter

Pin1 to Pin2= ??

Pin2 to Pin3= ??

P3 to Pin1 = ??

Pin4 to Spindle Body =

And check all Pins to the spindle body

If you can't do this you need to have it tested at a motor repair shop

[tazma]

I think I have got

P01 =400
P02=220
P03=200
P04=0000
P05=0000
P06=400
P07=0000

[mactec54]

I think I have got

P01 =400
P02=220
P03=200
P04=0000
P05=0000
P06=400
P07=0000

Does not sound very good you need the minimum frequency setting at P05=100 this is to protect the spindle

See what P20 is set at this may help with the frequency noise you may have to go higher or lower with that Parameter just watch the temperature if you go up higher this will change how it sounds
