uc300eth vfd connectios

[voyager1972]

Is the following correct, I can connect the voltage in, on the vdf to the 10v output on the analog port on the controller,,, then connect the acm to the ground pin on the analog port,,,,,,,, the other two wires I connect to the Bob,,, 1 to an output for direction the other th the 24v ground connection?,,, I am new to all this,,, I've managed to get everything else working except the spindle,,, fingers crossed, hopefully get it sorted

Depends on the VFD, often VFD as 2 sources for controlling the speed, Voltage or Current. usually marked V1 or A1 You want V1 for voltage and the Gnd goes to ACM.

The other two wires you speak of will be for Run (Forward) and these are usually sent through a relay. They often come from FOR and DCM(gnd).
You can use them directly with the Outputs but you will need to tie the DCM to the Gnd of DC source you are powering the controller with.
Personally I'd use the output to turn on a relay.!

here are the videos that show that the spindle does not turn

NB : it turns perfectly but, without noise, everything is perfect
