User Guide of EM730 Series Inverter 3.3.6 Wiring of analog output terminals The external analog meter connected to the analog output terminal M1 indicates a variety of physical quantities. Choose the output current (0-20mA) or (0-10V) via the jumper cap, M1 corresponding to J7. Set F03.34 as needed (0: 0-10V; 1: 4-20mA; 2: 0-20mA). The jumper cap and terminal wiring is as follows. 3.3.7 Wiring of 485 communication terminals The communication terminals A+ and A- are the RS485 communication interfaces of the inverter. The online control of the host (PC or PLC controller) and inverter is performed through the connection and communication with the host.
The connection of the RS485 and RS485/RS232 adapters to EM730 series inverter is shown in Fig. 3-16, Fig. 3-17 and Fig. 3-18. Direct connection of the RS485 terminal of a single inverter to the host for communication: A+ Inverter A- + terminal RS485 communicati on interface ON GND S1 GND - terminal of host Connection of the RS485 terminals of multiple inverters to host for communication: Fig.3-16 Communication Terminal Wiring of Single Inverter 27 M1 Inverter GND V I J7 M1 is for analog voltage output M1 is for analog current output
