Q: When will I choose the D740 series inverter?
A: D700 is a multi-function compact inverter, more portable, less than E700, the general function can be basically realized, simple start and stop can use D700 series.
Q: How should Mitsubishi inverter D740 be selected (one belt and one belt)?
A: The selection method of Mitsubishi inverter is consistent with reference to additional capacity and additional current. Generally speaking, the additional current of a frequency converter with a motor is greater than 1.1 times of the additional current of the motor if the selection conditions are satisfied.
Q: How should Mitsubishi inverter D740 be selected (more than one belt)?
A: The selection method of Mitsubishi inverter is consistent with reference to additional capacity and additional current. Generally speaking, the additional current of a frequency converter with multiple motors is greater than 1.1 times of the sum of the additional currents of multiple motors. If you start sequentially, you need to add 6-8 times the extra current of the last motor.
Q: Can the D740 inverter have a motor with the same power? Example: 7.5kw inverter with 7.5kw motor.
A: The selection method of Mitsubishi inverter is consistent with reference to additional capacity and additional current. The same power may not be completely compatible, we also have to verify whether the additional current of the inverter is satisfied, if the additional current of the motor X1.1 is greater than the additional current of the inverter, then there may be an overload alarm during operation, unable to operate.
Q: Can the high-power D740 inverter be equipped with a low-power motor, and the power difference is large?
A: The high-power inverter with the low-power motor is not stable, if the power segment is too different, it will also produce an alarm (E.LF) of the output phase loss, the power difference is too much, if the protection parameters are not set properly, it will also produce the situation of burning the motor, so the selection is still rigorous, and the inverter and the motor must be matched.
Q: Can the low-power D740 inverter be equipped with a high-power motor?
A: The selection method of Mitsubishi inverter is consistent with reference to additional capacity and additional current. Generally speaking, the additional current of the low-power inverter will be less than that of the high-power motor, so this selection is not possible, and the selection still refers to the additional current of the inverter is greater than 1.1 times of the additional current of the motor, and the selection is carried out together with power and current.

Characteristics of servos and advantages of Mitsubishi servos
The servo system is an automatic control system that enables the output of the object's orientation, direction, and state to change with the arbitrary change of the input quantity (or given value). In the automatic control system, the system that can echo the control signal with a certain degree of accuracy is called the follow-up system, also known as the servo system.
