First CNC build - VFD wiring question

[routercnc]

Hi OK, thanks for that and the extra info.

for the interest of this thread I've redone the schematic just so there's no one else following committing to fry their electronics.

Does this look correct? Many thanks

Hi rbs

Your new sketch still looks wrong on the speed control part. If the spindle control board is putting out a variable 0-10V to control the speed then in my view:

+ on the board should go to VI on the VFD
- on the board should go to ACM on the VFD

Don't connect anything to VR or AI for what you are trying to do.

Also, note that the manual shows a grounded shielded cable for the control cable (the dotted hoop around the input lines) to reduce interference.


*If any moderators are reading this it is probably more appropriate to move it to the electronics > VFD section . . .*
