I have a Siemens Simovert 6sv-1 100kw short paired with a Siemens 1PV4133WS20 motor. I'm using golf cart batteries for testing at the moment. I have them connected in series for a total of 160 volts. The reason I'm using them for testing is I have not witnessed this car moving yet and before spending thousands on batteries I want to make sure it will run.
I was getting the Prech. Time > 3s so I lowered the following to these numbers:

420 Ubat_UnderVolt 99.99V
421 Ubat_Min 110V
422 Ubat0_Min 110V
423 Ubat0_Max 170V
424 Ubat_Max 200V
425 Ubat_OverVolt 204.99V

Now when I turn the high voltage switch on, turn the ignition on, hit the start, all per Victor's Siemens Power Inverter installation instructions at Metric Mind, I get this error: Main_Contactor

Does anyone know what paramerter I should be looking at for this error message?

Thanks,
Ricky

Re: Siemens Simovert 6SV-1 100kW Main_Contactor error message

Anyone out there that can shine some light on the subject?

Thanks for the reply. If I remember correctly the voltage didn't change from when I checked before and after turning on the high voltage. I'll check again in a few days. I don't have a pre charge resister, should I get one? Not sure where, what kind to get. Thanks again!

I have no idea about what parameters you would change, but I would suggest that you need more information.

Do you hear the main contactor engage?

Have you measured the high voltage at the input to the inverter during and after the pre-charge?

Maybe you need a smaller pre-charge resistor or maybe you have another issue, but there isn't enough information here to do more than make a wild guess.

I do not hear the main contactor engage
I'm not sure what pre-charge is? Is this the time between when I turn the high voltage on and when I hit the 'start' button?
Where would the pre-charge resistor go? Where can I find one?

Thanks for the reply!
