[n0f8r]

finally got it going no relay needed

removed jumper then

A01 = VI
ACM = 5V0
DCM = 24V0
FOR = pin 7 port 1
REV = pin 8 port 1

pid001 on vfd = 1
pid002 on vfd = 1

Hi @fandtm666 - I'm also trying to get my Huanyang inverter working with an AXBB-E - Previously it was working with a chinese controller, but I need to run probe g-codes that it doesn't support, so I've been trying to upgrade to the axbb. I have it hooked up as you have now - but I've got problems - I'm worried that in my journey I've broken my inverter and that it's damaging my axbb.

With the inverter powered but nothing plugged into the inputs - I'm reading 24V on the FOR pin against DCM - see image. That seems very wrong to me - I don't suppose you could check your FOR voltage? no need to unplug anything - just see what the voltage is when the spindle is running and when it's not running.


thanks,
Kevin.
