6.2 Inverter and Sequence Protection
6.2.1 Open-phase Protection
Open-phase protection is used to prevent over current levels induced by the inverter inputs
due to an open-phase within the input power supply. Open-phase output protection is also
available. An open-phase at the connection between the motor and the inverter output may
cause the motor to stall, due to a lack of torque.
