Hi Folks,

I've been looking for instructions on setting up a Hitatchi NE-S1 inverter to work with Mach3. I have used a G540 to control it through PWM, however, i would like to get more precise control. I would like to use the serial interface on the computer or set up modbus to send commands to the inverter.

I do have a rs485 serial convertor wired to the VFD from the built in serial port. I have enabled serial and mod bus in mach, but I'm not sure how to test the connections, what commands to set up or anything else.

What are my next steps?
