High-voltage DC bus fault
These are typically poor electrical connections at breaker/contactor contacts, wire terminations, fuse clips. Consider arcing within windings of a transformer, line/load reactor, and motor. Measure line voltage on the drive L1,L2,L3 terminals (phase to phase) and check for any. This fault has several possible causes and this whitepaper explores each one, offering solutions to ensure proper VFD operation. Disclaimer: Troubleshooting or servicing a VFD or any electrical equipment should only be performed by qualified personnel familiar with electrical safety practices. The. A regenerative drive doesn't generate excess voltage on its own. Something in the system is pushing too much energy back ...
