WEG stand-alone drives are low voltage variable speed drives installed as individual units inside a control panel. With a built-in keypad, SoftPLC and plug-in accessories they can be commissioned without an external control system, and connected to industrial networks when needed.
WEG's low voltage drives catalogue splits this class into two groups. General-purpose and machinery drives include the 1/4–1 HP CFW100-G2, the 1/4–10 HP CFW320 and the 1/3–175 HP CFW500-G2, offering compact, economical solutions for pumps, fans and conveyors. The performance group comprises the 1.5–1,000 HP CFW11 and the 1.5–650 HP CFW900, aimed at demanding processes that require vector control, integrated safety and high overload capacity.
The CFW501 for HVAC applications and the modular CFW11M for higher powers are also part of the same portfolio. Euronorm provides technical support in selecting the right series and rating for your application.
Features
Stand-alone commissioning
A built-in keypad and guided start-up allow operation without an external controller.
Wide power range
Series from the CFW100 to the CFW11 cover power from 1/4 HP to 1,000 HP.
Built-in SoftPLC
The series offer PLC functions inside the drive, programmed with free WEG software.
Plug-in accessories
Communication, I/O, encoder and safety modules are added as required.
Common programming logic
WEG drives share similar menus and parameter structures, easing moves between series.
Applications
- Pump and fan drives
- Conveyor and material handling lines
- Compressors
- Extruders, mixers and centrifuges
- Heavy-duty applications such as cranes, crushers and mills
