CAUSE
Why does it occur?
Input voltage too low; Actual DC link voltage differs from display; Power blackout; Input phase loss; Faulty magnetic contactor on input; Large load on power system (welder, direct motor start, etc.)
REMEDY · Step by step
How to fix it?
Check if input voltage is below rating; Contact service center; Use speed search function; Check input wiring; Replace magnetic contactor; Increase power capacity
