4.3.3 When the rated motor frequency is 50Hz (Pr. 3)
First, check the motor rating plate. If a frequency given on the rating plate is "50Hz" only, always set Pr. 3 Base frequency
to "50Hz". Leaving the base frequency unchanged from "60Hz" may make the voltage low and the torque insufficient. It
may result in an inverter trip (E.OC) due to overload.
