★
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
recommended not to exceed two power segments.
★
When a high-power inverter is provided with a low-power motor, the motor
parameters must be entered accurately to prevent the motor from damage as a result of
overload.
The technical specifications of the A90 series inverter are shown in Table 1-2.
