Product Description
This an Isolated RS485 Modbus CNC I/O Module designed for use with the 6 Pack Universal CNC Controllers (need coming soon). It can be used to control RS485 spindle VFDs. Many types are supported. Check the wiki to see if your VFD is supported. The isolation prevents electrical noise and spikes from getting to the controller via the RS485 connection. RS485 Control is very robust and allow both precise speed control as well as direction control. The firmware constantly monitors the performance of the spindle and can stop your job if the spindle is not working properly.Product Description.
This module has automatic direction control so, no rts_pin assignment is needed.
Example Connection (Huanyang VFD Example)
