CFW500

Variable Speed Drive

Machinery Drive

Endless possibilities

With modern design, the variable speed drive CFW500 is a high performance VSD for applications that
require speed and torque control of three-phase induction motors. The equipment has sensorless vector
control, closed loop vector control or scalar V/f. It also has SoftPLC, which adds PLC (programmable
logic controller) functions, Pump Genius, which adds dedicated functions for pumping systems and
selectable plug-in modules, that provide a flexible and optmized solution for any application.

Flexibility and Performance

The CFW500 has a modern design and it can be selected according to the application requirements, providing flexibility with
excellent performance. The VSD gives the user the possibility to choose the plug-in module that best fits his application, or to
use the standard version, that comes with the CFW500-IOS plug-in module. All plug-in modules comes with one RS485 port
as standard.
The installation of the CFW500 is simple and its configuration and operation is intuitive with the navigation menus of the
operating interface (HMI) with built-in LCD display. By using the flash memory module, it is possible to download the
existing setting from one CFW500 to other units without powering them up.

Conformal Coating

Improved 3C2 class of coating
on the internal circuits of all
versions and extra 3C3 Class
coating (optional) according to
IEC 60721-3-3 ensures
improved protection in
environments with corrosive
chemicals.

Plug-In Modules

Selectable according to
the application.

Easily Removable Fan

The quick change system ensures simple and
fast fan maintenance.

.

SoftPLC

It is a software resource added to
the CFW500 which allows the user
to implement and debug logic
projects equivalent to a small PLC
(Programmable Logic Controller),
customizing and integrating the
CFW500 to the application. The
free WLP programming software
is available at:
