Abstract

See full text

A method for monitoring a controller for controlling and/or monitoring a three-phase electric motor, in particular an asynchronous or synchronous motor, wherein two phase currents are measured and an error signal is generated if at least one of the two measured phase currents is essentially zero. An error signal is also generated if none of the two measured phase currents is essentially zero, but a sum formed of the two measured phase currents is essentially zero.
