Inverter Signals
One of the main functions of the sbRIO-9687 is to provide an interface between the
sbRIO-9683 or sbRIO-9684 GPIC controller and up to seven single-phase Semikron inverters.
The following tables show the connections between inverter signals and the GPIC. Only one
connector from each column of the following tables can be used at a time. Using two
connectors from one column could result in unpredictable behavior or damage to the interface
board or inverters.
