Choosing the lead-in and lead-out c

Choosing the lead-in and lead-out cables of the frequency converter According to the power of the frequency converter, select a three-core or four-core shielded power cable with a suitable conductor section. In particular, the power cable from the inverter to the motor must be shielded and as short as possible, so as to reduce electromagnetic radiation and capacitive leakage current. When the cable length exceeds the output cable length allowed by the inverter, the stray capacitance of the cable will affect the normal operation of the inverter. Therefore, an output reactor must be configured. The length of the connecting cable between the inverter's peripheral components and the inverter must not exceed 10m.Because when the frequency drops, the voltage also drops. In the case of the same current, the proportion of the line voltage drop in the output voltage will increase, and the proportion of the voltage obtained by the motor will decrease. This may cause the motor to not move the load and heat up. Therefore, when determining the wire diameter between the inverter and the motor, the most critical factor is the influence of the line voltage drop.
