The Weg CFW300-IODF provides digital frequency inputs and outputs for the CFW300 series VFDs.
The module consists of 3 NPN transistor inputs, and 3 optocoupled open-collector transistor outputs. The frequency
range is from 10 to 3000 Hz. The frequency inputs and output values are only accessible by means of a SoftPLC application
running on the CFW300 VFD.
