General Mach Discussion / BEWARE - Huanyang VFD will probably not work via RS485
« on: August 30, 2010, 08:05:04 AM »
Like many others on many forums I have just spent my weekend and many evenings attempting to get my new CHEAP 2.2Kw Spindle and Huanyang VFD working with Mach3 using RS485 and Matt Zee's plug-in.
As it has been discovered by others that the RS485 chip (IC U4) is missing form many units purchased by forum members.

Be aware of this, If you plan to only use the VFD with manual or switched control that is OK, If you plan to use RS232 to RS485 for control then you not be able to do so.
I thought I should highlight this shortcoming by starting a new link and hopefully save many hours of wasted research by others!!!!
Good Luck
