The Drive Overheat Fault (OHF) indicates that the heat sink temperature has crossed the temperature threshold. This is the information from the temperature sensor located on the heat sink, near the transistor module. When the Thermal Heat Dissipation (THD) is greater than 118% it trips in OHF. 118% is approximately 100 Deg Centigrade temperature on the heat sink.
