Questions & AnswersAsk a Question
Can you control a VFD with 0-10V signal? I have a G-Shield and Protoneer CNC Shield, I don't want to pay over $500 for an Inventables x-controller and wait 8 weeks (currently) if your board can do this?
Yes absolutly, its one of the reasons we made the AIO.
Have a look here: http://3dtek.xyz/pages/grblaio
There are two pins you need to conenct to shown as connector item 12 in the first image.
This Spindle control output connector (12) has 4 pins
GND & PWM runs a pulse width signal for controlling DC spindle speed controllers and alike so your not looking for this combination.
GND & 0-10 runs a 0-10V signal for controlling speed of a VFD. This is the combination your after.
Direction goes high or low to suggest direction (not generally used).
Your VFD likely has a 10V or 12v output to help generate this 0-10V signal but we dont need to use that as we generate our own voltage.
If you conenct the ground to your VFD's analog ground (NOT MAINS GROUND) and the 0-10 to one of the analog inputs, you should be able to instruct the VFD to listen to that input for its speed signal. If you get stuck send a link to your VFD manual and we might be able to help further.
Does the AIO support XYZ & Tandem A via the external driver connector.
Yes, the jumpers on board that control which axis is slaved over to A also send the slaved direction and step signals to the A output on the external driver connections.
Where do i coonect E-STOP on card I
Estop connects to both Gnd and A on the 5 pin 'control' port which has pins labelled Gnd, P, R, FH, and A. (ground, Probe, Resume, Feed Hold and Abort)
Use the normally open side of the Estop switch - its the green side.
