Schneider ATV71HD22N4S337 Altivar 71 Variable Frequency Drives VFD

Schneider ATV71HD22N4S337 is a frequency converter in Schneider ATV71 series. The following is its specific information:

Power: The motor power is 22kW (30hp), which is suitable for driving medium-power AC motors and meeting the needs of some equipment with high power requirements, such as small fans, water pumps, conveyor belts, etc.

Voltage: The power supply voltage range is 380-480V (-15%-+10%), 3 phases. This voltage range can adapt to the power supply conditions of most industrial occasions and has good versatility and stability.

Current: When the power supply voltage is 380V, the line current is 50A; when the power supply voltage is 480V, the line current is 42A. The power supply line and protection device can be reasonably selected according to the actual power supply voltage and motor load.

Functions and configurations: It belongs to the ATV71 series and has many advanced functions of the series, such as the use of flux vector control technology to achieve high-precision speed and torque control; it has more than 150 functions, including PID controller, brake control for walking, lifting and slewing motion, etc.; it integrates Class A EMC filter, which can effectively reduce the electromagnetic interference of the inverter to the power grid and improve its own anti-interference ability; it also integrates Modbus and Canopen communication interfaces, which are convenient for communication and networking with other devices, and can realize remote control, monitoring and parameter setting functions through the communication network.

Application scenarios: It is suitable for a variety of complex industrial application scenarios, such as vertical lifting, translation and slewing motion control of lifting equipment such as cranes, overhead cranes, and gantries, as well as drive control of high-inertia and unbalanced mechanical equipment such as centrifuges, mixers, beam pumps, and presses.

However, it should be noted that the ATV71 series has been replaced by the ATV930 series. However, due to its widespread use in the industrial field, there are still a certain number of ATV71HD22N4S337 inverters in operation on the market, and there are also related maintenance services and spare parts supply.
