Lenze 8400 StateLine frequency inverter The 8400 StateLine frequency inverter is suitable for speed control with simple motion control. The requirements of the Ecodesign Directive, Standard EN IEC 61800-9-2, are met. Application areas: Transverse materials handling equipment, palletizers (intralogistics), extruders (plastics industry), filling systems (packaging industry), ... Highlights For drive tasks with or without speed feedback Integrated brake management "VFC eco" energy-saving function The features and advantages of the Lenze 8400 StateLine frequency converter are as follows: 1. **Control Performance** - **Diverse Modes**: It has sensor - less vector control and sensor - less control for synchronous motors. It can be adapted to different motors and applications, enabling precise control regardless of whether there is speed feedback or not. - **Excellent Overload Capacity**: It can withstand an overload current of 200% (for 3 seconds) and 150% (for 60 seconds), coping with conditions such as startup and overload to ensure the stable operation of equipment. 2. **Functional Applications** - **Remarkable Energy - saving**: The "VFC eco" function monitors and optimizes the operation of the motor in real - time. It can achieve high - efficiency energy - saving under different loads, reducing costs. - **Perfect Braking**: The built - in braking management reduces the losses during process stops, decreases the wear of braking components, and improves safety and reliability. - **Rich Interfaces**: It has digital input/output (5/1), analog input/output (1/1), relays, etc. It is also equipped with various communication - related configurations, facilitating the connection and communication of equipment as well as the integrated and intelligent control of the system. 3. **Safety Performance** It has the Safe Torque Off (STO) function and has passed the EN 13849 - 1 (Cat. 4, PL e) and IEC 61508/EN 62061 (SIL 3) certifications. In critical moments, it can quickly cut off the torque output of the motor to protect personnel and equipment. 4. **Environmental Adaptability** The operating temperature ranges from - 10°C to 55°C. Above 45°C, the capacity is derated by 2.5%/K, enabling it to adapt to harsh industrial environments. 5. **Other Advantages** - **Compliance with Standards**: It meets the requirements of the ecological design guidelines and the EN 50598 - 2 standard, demonstrating its advantages in environmental protection and sustainability. - **Convenient and Easy to Use**: It adopts a plug - in technology, which is simple and convenient for installation and debugging, saving time and improving efficiency.
