what causes a motor to suddenly stop running after initializing

1 comments:
Mr. Anderson
February 3, 2025

The LSIS SV-iG5A Series motor may suddenly stop running after initializing due to a Low Voltage trip. This can occur if an instant power failure lasts longer than 15 milliseconds or if the output load exceeds the inverter's rating. Additionally, the inverter's DC link voltage can vary based on the output load, which may also contribute to this issue.
