VFD CMD

DELTA RS485 Splitter VFD-CMD 04/08 Instruction Sheet To complete the communication function of VFD inverter and DVP PLC, Delta produces multi-machine communication board by itself. RS-232 communication port of PC connects to the input terminal of this multi-machine board via RS-232/RS485 converter. An inverter can connect to multiple inverters by using this communication board (1 to 4 to 8) to control multi-machine communication. The diagram is shown as following: INPUT SG- SG+ SG- SG+ 3: SG- 4:
