User Manual of EM730 Series Inverter Fig. 7-31 Timing Parse Diagram of Complete Data Frame The EM730 series inverter supports the master-slave communication function. That is, one inverter works as the host and others as slaves. The slaves work according to the command sent by the host, so that these inverters can work synchronously. The inverter used as the host is set as follows: F10.05=1: enable the master-slave communication function; the host in a network); F10.06=1 or 2: select the current inverter as the host (only one inverter can be set as F10.07: select the variable to be synchronized, such as the output current (set F10.07=5).
The inverter is used as the slave is set as follows: 254 Function code Function code name Parameter description Unit Default setting Attribute Mailing address F10.05 Options of master-slave communication function 0: invalid 1: valid 0 〇 0x0A05 F10.06 Master-slave options 0: slave 1: host (Modbus protocol broadcast transmission) 0 〇 0x0A06 F10.07 Data sent by host 0: output frequency 1: set frequency 2: output torque 3: set torque 4: PID setting 5: output current 1 〇 0x0A07 F10.08 Proportional factor of slave reception 0.00~10.00 (multiple) 1.00 ● 0x0A08 F10.09 Host sending interval 0.000~30.000 s 0.200 ● 0x0A09
