(3) The motor power are just reference values; they are specified for WEG 4-pole 690 V motors for models with DC power supply of 758...1150 Vdc. The proper
sizing must be done according to the rated current of the motors used.
(4) All dissipated powers obtained using the maximum input voltage, rated current (ND or HD), maximum output voltage and switching frequency of 2.0 kHz.
All indicated losses are for the worst case.
