I need help hooking up a Delta VFD-M MODBUS to work with MACH 3.
It is the VFD022M21A
Manual is here http://www.automatedpt.com/wp-conten...ser-Manual.pdf
It shows to have an RJ11 jack for the RS-485 serial interface.
Do I take a RJ 11 plug and using an RS-485 to RS-285 converter to my serial port? It also has terminals M0 to M6.
I'm not an electrical engineer so tell me in simple terms about how to proceed.
I managed to get through the entire build of a cnc router and use it daily for about a year before I decided it would be good to get it finished up. The spindle is hooked up and running this is just about the MODBUS hook up.
