Main protective functions of inverter Thermal protection against power stage overheating
Protection against short circuits between the motor phases, line phase failures, over-
current between output phases and ground, overvoltages on the DC bus, interrup-
tions in the control loop, exceeding the speed limit. Safety function for: Over- and
undervoltage of the power supply system, line phase failure with 3-phase supply
Motor protection Thermal protection integrated in the inverter through continually cal-
culating the l²t value while taking the speed into consideration:
-The thermal state of the motor is stored when the frequency inverter is switched off.
-The functionality can be adjusted according to the motor type
(external cooling or self-cooling) using an operator interface.
Protection against motor phase failures
Protection provided by PTC sensors
