The Schneider ATV71HD22N4 Variable Speed Drive is a robust and versatile solution designed to enhance the performance and efficiency of complex, high-power machines. Engineered for three-phase motors with a power rating of 22 kW and compatible with a supply voltage of 380 to 480 V, this drive is an ideal choice for a wide range of industrial applications.
Featuring an integrated EMC filter and a heat sink assembly style, the ATV71HD22N4 ensures reduced electromagnetic interference and optimal thermal management. Its nominal output current stands at 40 A at 4 kHz for 460 V three-phase motors, making it suitable for demanding operations.
The drive boasts an output frequency range of 0.1 to 599 Hz and a nominal switching frequency of 4 kHz, which can be adjusted up to 16 kHz with a derating factor to accommodate various application needs. The asynchronous motor control profile includes an ENA (Energy adaptation) system for unbalanced loads, flux vector control with sensor, sensorless flux vector control, and a voltage/frequency ratio with two or five points, providing precise control and adaptability.
With a prospective line Isc of less than or equal to 22 kA for three phases, the ATV71HD22N4 ensures reliable protection against input phase loss, overcurrent, overheating, and other potential issues. The drive's transient overtorque capability can handle up to 220% of nominal motor torque for short durations, offering robust performance during sudden load changes.
The Schneider ATV71HD22N4 is designed with user-friendliness in mind, featuring a type of polarization with no impedance for Modbus, facilitating easy integration into existing control systems. Its full functionality and compatibility with synchronous motors make it a comprehensive solution for enhancing the control and efficiency of industrial motor-driven systems.
