1. The voltage level is consistent with the control motor.
2. Select the type of frequency converter based on the load characteristics of the controlled equipment, and for constant torque loads, it is best to choose a frequency converter with a wide driving torque limit.
There are three types of loads: constant torque loads, fan loads, pump loads, and constant power loads.
3. Working environment
a. The requirement is -10 ℃~50 ℃, preferably controlled below 40 ℃.
b. If the work site has large dust, high temperature, high humidity, and contains corrosive gases, corresponding protective measures must be taken.
