ACS800 Inverter Fault
We use ACS800 inverter to control big blower. since we could not de-couple the motor, we have to set the motor identification method to 'ID MAGN (ID Magnetisation)'. when ID MANG is requested via control panel, we start the inverter with selector switch. but supply unit(rectifier) contactors energizes for only one second and this fault appears on control panel:
MAIN CNT FLT(FF17)
I searched tis fault in documents but did not find it.
Appreciate if help me to clear this fault.
Don't find such error.
From the fault description, it could be Main Contactor Fault - if the contactor switches on, even shortly, you should check if the feedback for contactor ON status is connected correctly - aux. contact of this contactor should be connected somewhere in control modules of the inverter, showing to the drive that this contactor is switched on
