输出端子，包括变频器运行状态信号输出、故障接点输出等。

电动机额定电流法。选择变频器容量的过程实际上是变频器和电动机之间最佳的匹配过程。最常见和更安全的方法是使逆变器的容量大于或等于电动机的额定功率，但实际匹配时应考虑电动机的额定功率。实际功率与额定功率之差通常是所选择的电动机容量。设备太大，但实际所需容量很小。因此，根据电动机的实际功率选择变频器是合理的。。对于轻负载，通常应根据1.1 In（In是电动机的额定电流）选择逆变器电流，<br>该设计使用成熟的三菱通用变频器FR-A740-45K。

Motor rated current method. The process of selecting the capacity of the inverter is actually the best matching process between the inverter and the motor. The most common and safer is to make the capacity of the inverter greater than or equal to the rated power of the motor, but the actual matching should consider the motor's The difference between the actual power and the rated power is usually the selected capacity of the equipment is too large, but the actual required capacity is small. Therefore, it is reasonable to choose the inverter according to the actual power of the motor. . For light loads, the inverter current should generally be selected according to 1.1 In (In is the rated current of the motor), or according to the maximum motor power indicated by the manufacturer in the product that matches the output power rating of the inverter.This design uses the mature Mitsubishi general-purpose inverter FR-A740-45K.<br>
