In the communication between PLC and VFD-B series AC motor drive (ASCII Mode, M1143 =OFF), executes Retry when communication time-out, data receiving error or parameter erroroccurs2. When X0 = ON, PLC will write data H1770 (K6000) into address H0100 in device 01 (VFD-B).3. M1129 will be ON when communication time-out occurs. The program will trigger M1129 andsend request for reading the data again.4. M1140 will be ON when data receiving error occurs. The program will trigger M1140 and sendrequest for reading the data again.5. M1141 will be ON when parameter error occurs. The program will trigger M1141 and sendrequest for reading the data again.
