VFD ASKPOWER A131 Need Help!

[JAZZCNC]

Is there a jumper in the VFD to change control from VFD to BOB jumper 1 needs to be set on my HY VFD I think.

No jumpers have to be set on the HY vfd's unless you changed the default jumper to use External POT for speed reference.

Hi Jazz yes I did use the command when testing m3 s10000 . This would then make a clicking sound and the relay light on the BOB would come on.

Ok well so sounds Mach3 is set up correctly for ON/OFF so now check you have voltage coming out from speed control. Command half the speed you setup the spindle pulleys for and should get close to 5v.

If this works then check parameters in VFD are set for External ON/OFF and Speed Ref. If yes then it must be a wiring issue or the Digital input your using is set for another function so check this also.

Are you feeding the BOB with the required 5V and 12-24V? Measure the voltage across the two 0-10V pins on your BOB at various speeds to see if you are actually getting it to pulse.
