Vfd and axbb-e problems

Postby ainboa » Mon Jan 24, 2022 3:39 pm

Hello to all,

I am a brand new user of axbb-e and uccnc, I changed the controller of my chinese cnc for yours, I wired the motors and they work in the right direction. My concern now is the spindle control.

I wired it like this:

FWD > O2
DCM > 24V0
ACM > 5v0 power out
AVI > AO1

The problem is that I can't turn on the spindle from Uccnc

If someone has an idea of why I'm interested :)

Are the signals OK at the VFD?
The FWD to DCM Voltage is 0Volts when activated?
And the AVI analog input to ACM is higher than 0Volts?

These 2 things together make the VFD to run the motor if the VFD is setup correctly to input the analog signal from the screw termianl and to input the FWD start signal also from the screw terminal.
If these 2 things are OK then the motor should run, if not then the VFD parameters are not setup correctly.

Thank you very much, I will look tomorrow for the voltage measurements.

On the other hand I'm a bit lost in the pin settings on uccnc for the spindle.

I don't know what to activate, I've tested many things but nothing works
