Yes, you can control the speed of the 2.2 kW spindle, and the other spindles we sell, through Mach3 software. The first thing you will need is the dynamic link library to pair with mach3 called the Huanyang VFD Mach3 PlugIn. But it is written with the presumption of using a particular USB to RS485 converter and this is the reason why on. The following are instructions on how to connect the VFD to Mach3 via this RS-485 serial connection. There is a Mach3 plugin written specially for the Chinese Huanyang brand VFD used by many people. Please also don't forget to uncheck the 'Disable Spindle Relay' checkbox if you haven't done so already as it will prevent some of the spindle M commands from operating. For a long time Ive been trying to make Mach3 control the spindle over the RS485 communication line. I completed all of this at the one time, so I can't be sure which part was the most effective but it is now a totally stable and usable machine. I also added an EMI filter on the input of the VFD which connects in series between the 240v outlet (Aus) and the mains plug on the VFD. Please also ensure that you also use a shielded twisted 2 core cable for the RS 485. I also cut some small ferrite cores of an old VGA cable and added one to each end of the RS 485 cable. I shielded both ends of the spindle cable and added an earth to the spindle, PC and controller box in a star configuration. I was getting false stops and Mach3 would hang as soon as the spindle started. Only set up in UCCNC is in configuration, set spindle velocity min to 8000(rpm) and max to 24000(rpm). I also earthed everything back to a single star point and now I could not be happier. Hello Everyone, If you were using a Hunayang plugin for Mach3 to control VFD/spinde or using Spindle Talker than this macro's for you. I too was having major issues with the same setup until I rewired my spindle with shielded cable.
