Russtuff just uploaded a quick video showing how to program a Huanyang VFD that might be helpful.
https://www.youtube.com/watch?v=7OszQS_BQMk He's programming it for RS485 control, which would be nice now that Huanyang VFD support is in LinuxCNC 2.7 and above. I think many of the Huanyang inverters do not support the com port and it's difficult to tell which do from a visual inspection. The eBay specs are usually cut-and-paste and are often incorrect. I've read that even if the Huanyang VFD has the proper chipset to support the com port, it may not have the hardware as a cost saving "feature". I have a few of these VFDs. I should connect them to a motor one at a time and see if any of them support RS485, and use that for future CNC projects instead of relays and 0-10V analog control if possible. However, even if you aren't interested in RS485, you might be interested in the part of the video that deals with the parameters for ramp up time, ramp down time, motor current, etc. On 07/25/2016 02:56 AM, Gene Heskett wrote: >>> Greetings to you who are running an inverter driven spindle; I have >>> one of those 1 HP 230 volt 3 phase motors on the table, in this case >>> the one with the noisy bearings but it still rolls dead free.
