Main protective functions of inverter
|
Thermal protection against overheating Protection against short circuits between motor phases Overcurrent protection between motor phases and ground Protection against overvoltage and undervoltage on the mains supply Protection against mains phase failure on a 3-phase supply

Motor protection
|
Thermal protection through continually calculating the l²t value integrated in the inverter
