NORD DRIVESYSTEMS frequency inverter solutions are based on cost effective and scalable equipment options that begin with basic entry level drives from 0.75 to 90kW power output with a comprehensive choice of expansion possibilities that add communication, position feedback, PLC programming, safety, I/O expansion and many other functions to exactly match the application requirements. In this way, simple sensorless speed control or complex multi axis servo positioning systems with IEC 61131-3 functionality and SIL Safety can be realised with the same modular hardware, software, parameter structure, and commissioning requirements; for complete consistency.
