Pleaserefer to Section 6.2 for details.Example 5: Access errorIf take any action using PKW to access parameter in AC Drives and it fails, PD-01 willresponse error information. Suppose that Master send data sequence is 202D 80000000 0002, if VFD series Drives does not find this address (0x07FD), it will respondthe data sequence 702D 8000 0000 0000, response ID is 7 which means cannotprocess request (with error number), and error number is 0 (Illegal ParameterNumber).Request ResponseWord 1 (PKE) 202D Word 1 (PKE) 702DWord 2 (IND) 8000 Word 2 (IND) 8000Word 3 (PWE1) 0000 Word 3 (PWE1) 0000Word 4 (PWE2) 0002 Word 4 (PWE2) 0000Response time about PD-01The update time via PROFIBUS connection can be divided in 3 parts: T1: Communication time in transmit data from the master to PD-01, and T2: Wait processing in data buffer of PD-01, and T3: Communication time in transmit data from PD-01 to VFD Drives.T1 T3Master Data BufferTimerPD-01VFDseriesDrivesT2
