3.4 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 voltag low and the torque
insufficient. It may result in an inverter trip (E.OC
) due to overload.
