CFW500 FAQ
How do I select the right WEG VFD for my application?
Consider motor horsepower, voltage, duty cycle (heavy-duty vs normal-duty ratings), required control mode (V/Hz, vector, or torque), communication protocol needs, and environmental conditions. Contact Gross Automation for application-specific sizing assistance.
Do WEG drives include built-in PLC functionality?
Yes. Most WEG CFW series drives include SoftPLC functionality with IEC 61131-3 programming. The CFW11 and CFW500 series feature extensive logic capabilities that can eliminate the need for external PLCs in many applications.
