User Manual of EM730/EM730E Series Inverter ★ Correct selection of the inverter: The rated output current of the inverter is greater than or equal to the rated current of the motor, taking into account the overload capacity. ★ The difference between the rated power of the inverter and that of the motor is usually ★ When a high-power inverter is provided with a low-power motor, the motor parameters recommended not to exceed two power segments. must be entered accurately to prevent the motor from damage as a result of overload. The technical specifications of the EM730/EM730Eseries inverter are shown in Table 1-2.
