Lenze AC drives, also known as variable frequency drives (VFDs) or inverters, are electronic devices used to control the speed and torque of AC motors. They convert fixed-frequency AC power from the mains
supply into variable-frequency AC power to precisely control the motor's speed and torque. Lenze offers a wide range of AC drives to suit various industrial applications.
Key Features and Specifications
Voltage and Current: Lenze AC drives are available in a wide range of voltage and current ratings to match different motor sizes and power requirements.
Control Modes: They support various control modes, including V/f control, vector control, and sensorless vector control, providing precise control over motor speed and torque.
Communication: Lenze drives support multiple communication protocols, such as Ethernet, CANopen, and PROFIBUS, allowing for easy integration into automation systems.
Safety Features: Many Lenze drives incorporate safety features like safe torque off (STO), safe speed monitoring (SSM), and safe direction (SDI) to enhance machine safety.
Additional Features: Other features may include energy-saving functions, built-in PLC functionality, and advanced diagnostics.
