I looked at the manual: http://www.hitachi-america.us/supportingdocs/forbus/inverters/Support/WJ200_Instruction_NT325X.pdf and saw that there is no shortage of available registers. Starting with B-24, one can see that there are more than few registers (all the way to B-48) available for configuring, monitoring and running the VFD, so Modbus offers a lot of capability. You certainly can effectively run the VFD with the control terminals, but if you want more, Modbus or the USB port are options. It should not be too difficult to expand the existing wj200_vfd component to support any of the registers listed. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/ ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
