Instead of sending and receiving information to and from frequency converters through I/O, you can connect them to a fieldbus. Vacon NX frequency converters can be connected to the DeviceNet using a fieldbus board. The converter can then be controlled, monitored and programmed from the Host system.

The tens are displayed with red blinks and the ones with green blinks. The unit plays the tens, then the ones and finally delays about 2 seconds before repeating the sequence.
Lead the DeviceNet drop-line cable through the right gridded hole on the bottom of the Vacon NX frequency converter. Make a sufficiently wide opening for the cable by cutting the grid as wide as necessary (see step E on page 12) Connect the 4 coloured wires into the bus connector in the following order from the left: black, blue, NONE, white, red.

MAKE SURE THAT THE FREQUENCY CONVERTER IS SWITCHED OFF BEFORE AN OPTION OR FIELDBUS BOARD IS CHANGED OR ADDED! NOTE Before taking any commissioning actions, carefully read the safety instructions in Vacon NX User’s Manual, Chapter 1. Vacon NX frequency converter Remove the cable cover.
