When the motor magnetic flux reaches to therated magnetic flux, the pre-excitation current matchesthe rated pre-excitation current.161 00.0Factory Default: 100.0 % 100.0FU1-20: Maximum FrequencyFU1-21: Base FrequencyFU1-22: Starting FrequencyFU1► Max freq20 60.00 Hz2060.00Factory Default: 60.00 Hz 60.00FU1► Base freq21 60.00 Hz60.00Factory Default: 60.00 Hz 60.00FU1► Start freq22 0.50 HzFU1-20 [Maximum Frequency] is the maximum outputfrequency of the inverter. Make sure this maximumfrequency does not exceed the rated speed of the motor.FU1-21 [Base Frequency] is the frequency where theinverter outputs its rated voltage. In case of using a50Hz motor, set this to 50Hz.FU1-22 [Starting Frequency] is the frequency where theinverter starts to output its voltage.21220.50Factory Default: 0.50 Hz 0.5091
