User Manual of EM730 Series Inverter It is dedicated to the straight wire drawing machine of the winding and unwinding application micro. When F27.00 is set to the option 3 (straight wire drawing machine) and the feedback signal is the maximum value for a long time after startup, the system will be adjusted by PID to the negative output. F09.43=0 : No limit When the output is reduced to 0, it will not be limited and may continue to decrease. F09.43=1: limit When the output is reduced to 0, it will be limited and not continue to decrease.
7.11 Communication Function Parameter Group of F10 Group The EM730/EM730E series inverter supports the RTU format Modbus protocol, and the “single-master multi-slave” communication network with RS-485 bus. address. Its setting range is 1 to 247. That is, a network supports 247 slave stations at most. For the entire communication network, the inverter as a slave must have its own unique ★ 0 is the broadcast address, which does not need to be set. All slave inverters can be recognized. receiving principles (e.g. baud rate, data format, and protocol format) to ensure normal The slaves and hosts attached to the same network must follow the same sending and communication.
Hence, there are three corresponding function codes, i.e. F10.01 (baud rate), F10.02 (data format) and F10.10 (protocol format, Modbus-RTU protocol by default for the EM730 series inverter). The devices connected to the network must have the same settings. During the communication based on the Modbus-RTU protocol, the EM730 series inverter supports six different baud rates in bps (bit/s). Take F10.01=9600bps as an example. It means that data is transmitted at a rate of 9600bits per second. By default, each byte consists of valid 251 Function code Function code name Parameter description Unit Default setting Attribute Mailing address F10.00 Local Modbus communication address 1-247; 0:
