VFD Tripping an RCD

[EddyCurrent]

If the drive has stood a while then the DC link capacitors may need to be 'reformed', this is how to do it on an ABB drive

Guide for capacitor reforming

I also says in the manual;
"WARNING! Disconnect the EMC filter when installing the drive on an IT system (an ungrounded power supply or a high-resistance-grounded[over 30ohms] power system), otherwise the system will be connected to ground potential through the EMC filter capacitors. This may cause danger or damage the drive. Disconnect the internal EMC filter when installing the drive on a corner-grounded TN system, otherwise the drive will be damaged. NOTE: When the internal EMC filter is disconnected, the drive is not EMC compatible without an external filter"

It's unlikely you suffer from this problem but maybe you are fed from a local transformer ?. A friend of mine had a local transformer just for his property and RCD's tripped all the time.
