EXCEL VRL CX/CXL/CXS frequency drive (VFD) is an electronic device for control of speed and torque of three-phase alternating current (AC) motors. VFD converts the fixed frequency and voltage of the main supply (mains) to a variable frequency and voltage, which can then be regulated to provide flexible motor operation and reduce energy consumption. EXCEL VRL CX/CXL/CXS frequency converters can be connected to LONWORKS network by using CX203OPT option board. The converter can then be controlled, monitored and programmed from the LONWORKS network. EXCEL VRL CX LONWORKS option board follows Variable Speed Motor Drive Profile.
The used I/O can also be extended by the LONWORKS option board:
The Interface board should be installed into the external option enclosure outside the frequency converter.
The VFD configuration screen has two screens – VFD_Configuration_Screen, which is the main screen, and an advanced user screen which is known as Advanced_VFD_Configuration_Screen. The configuration screen helps you configure the motor parameters.
