WEG CFW700 Frequency Inverter

Feature & Principle

It adopts WEG Vectrue vector control technology. It can realize open-loop sensorless torque control or closed-loop high-precision speed regulation with encoder feedback. The integrated SoftPLC function can complete simple logic control without external PLC. It supports PID constant pressure regulation, flying start, power ride-through function. The HVAC version integrates DC bus inductor to meet harmonic standard. It adopts plug-and-play expansion modules, RS485 Modbus communication, intelligent fan cooling monitoring.
