  • Page 159 Each object is formed by a sequence of ASCII characters For the CFW-08 are only available basic information formed by three objects: Object 00 - VendorName: always ‘WEG’. Object 01 - ProductCode: formed by the product code (CFW-08), plus the rated inverter current.

  • Page 160: Communication Errors

    In the example the Object Value has not been represented as hexadecimal value, but with corresponding ASCII characters. For instance, for the object 00, the ´WEG‘ value has been transmitted as being three ASCII characters, that as hexadecimal have the values 57h (W), 45h (E) e 47h (G).
