CJ1M Serial Port to JV Inverter?

2 posts in this topic

Hi, Does anyone know how I can communicate to a JV inverter to change speeds, start, and stop using the CPU's RS232 port on a CJ1M-CPU11? I want to eliminate the need for an scu module to get some of the cost out of the project... Thank you

jstan2700, I would look at using serial gateway on the host link port(assuming CJ is Ver. 3.0 or greater) and sending Modbus RTU commands to the 3G3JV drive through the CMND command (FINs command 2804 Hex). Cheers.
