Q : Connecting External Power to Drive Output (U/V/W) in Standby?

Views : 2

A: This is a strictly prohibited operation. It will cause a serious fault and will immediately damage the drive. The most direct consequence is the burnout of the inverter module (IGBT) inside the drive and its driver circuit. Therefore, it is forbidden to connect any commercial power source (or any voltage source) directly to the U/V/W output terminals of the drive.
