Can you talk to the drive with the Toshiba program? If not, looks like an interface issue Assuming it works - by default the VFS11 interface is in "Toshiba inverter protocol " mode You need to set it to Modbus mode with the Toshiba utility or through the panel, only then you can talk modbus to it. While at it, set serial rate to 19200, it's the maximum the VFS11 supports. -m > > Thanks! > > -- > Andrew > ------------------------------------------------------------------------------ > Slashdot TV. > Video for Nerds.
