I have been searching for a while for a clear resolution to this problem so i am hopeful that someone here can point me in the right direction. I have an HY series Huanyang VFD and spindle that is working quite well under Mach3 using a RS-485 and the Huanyang plugin. I am wanting to move to Mach4 and am running into issues with trying to figure out what I need to make this VFD work with Mach4, or if I am going to have to upgrade this thing. As I understand it, the HY version does not implement adhere to the modbus standard and this is why a special plugin is required. I have tried to configure using the Mach4 ModBus plugin and Bill Caldwell's write up on 'Connecting a VFD to Mach4 through Modbus (RS485)' with no success. If there are devices out there that convert PWM to whatever the HY series is accepting, I am not able to identify anything. I use the Ethernet Smoothstepper as my controller if that helps at all. If I must upgrade in the end, what are some recommendations this group may have on what would be a good option to purchase?
Any help you all can be would be greatly appreciated! Thanks.
