L7NH
LS Electric L7NH – Servo Drive with Real-Time EtherCAT Network Control
The L7NH series is part of LS Electric’s advanced servo drive family, designed for high-precision and synchronized applications that require real-time control. These drives support EtherCAT network communication, ensuring fast and reliable data exchange between the controller and the drive.
The models are divided according to supply voltage and power range:
- L7NHA (3×230 V): 0.1 – 3.5 kW
- L7NHB (3×400 V): 1 – 15 kW
These servo drives are ideal for demanding industrial systems where high responsiveness, accuracy, stability, and easy integration into existing network structures (PLC or CNC controllers) are essential.
