My CNC router spindle only seems to have three speeds, full, very slow and off. I checked the wiring to the VFD and it has all the inputs for full control (direction, +-10Volt input etc.) The controller board seems to have all the required outputs as well, but not wired. Wired for 2 digital outputs & Fwd only.
I have no problem setting up the VFD but the controller info is not very clear. Is there anybody out there that has a detailed understanding of how to setup the controller and what all the spindle and voltage settings mean?
There appears to be up to 4 speed control lines available apart from the normal analog control. The VFD has 4 digital inputs that can provide 16 preset speeds if required as a last resort. I am looking for direction and non stepped speed control?
I got no problem with electronics & control.
