When the rated motor frequency is 60Hz (Pr. 3)

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