User Manual EM303B General Purpose Inverter Inverter address code is the address code allocated to each inverter when the inverter is connected to the computer network. Each address code is unique in this network. The maximum number of inverter is 247 which are permitted to connect to the computer in one network. F1-16=0 Address code is broadcasting address. F1-17=0 Communication Bit Rate: 4800bps F1-17=1 Communication Bit Rate: 9600bps F1-17=2 Communication Bit Rate: 19200bps F1-17=3 Communication Bit Rate: 38400bps F1-18=0 No parity F1-18=1 Even parity F1-18=2 Odd parity F1-19 Select the present inverter as the master or the slave. F1-20 Set on the master inverter.
Select the frequency setting command of slave inverter sent by master inverter, and then send F0-07 or F9-06 to the slave inverter. F1-21 When the inverter is the slave, (the frequency sent by master inverter* F1-21) will be the setting numeric frequency of the slave inverter. Remarks: See Chapter 12 for EM303B ModBus communication protocol and examples. 94 No. Function Range Unit Default Type Communication Bit Rate 0: 4800 1: 9600 2: 19200 3: 38400 bps 1 〇 F1-17 No. Function Range Unit Default Type Communication Parity Mode 0: No parity 1+8+1 for RTU 1: Even parity1+8+1+1 for RTU 2: Odd parity 1+8+1+1 for RTU 0 〇 F1-18 No. Function Range Unit Default Type Master-slave Communication Mode 0:
