Operation principle
The sampled analog phase currents are pre-processed and for each phase current the
RMS value is derived. These phase current values are fed to the thermal overload
protection, one time constant LFPTTR/LCPTTR (26) function. The temperature is
displayed either in Celsius or Fahrenheit, depending on whether LFPTTR/LCPTTR
(26) function is selected.
