Schneider Altivar 320 wiring / setup help needed

[Neale]

You have the BOB 12V pin connected to the 10V output pin on the VFD. This definitely looks wrong. No connection needed here.

Otherwise, analogue out and ground pins look fine. From the data you give, it looks as if you have configured the VFD for 0-5V speed input, which is correct for that BOB.

As m-c says, that analogue signal is just for speed control. You also need at least one connection from a digital output pin on the BOB to one of DI1-6 on the VFD. The VFD manual should tell you which pin but these can often be reconfigured. Look for an input called something like Run. There will probably also be an input marked For/Rev. However, sometimes these are configured as two pins, one for forwards and one for reverse. For normal router use, you can forget reverse as you only want to run the spindle in the forwards direction. So, you need the analogue signal to set the speed and the digital signal to turn the VFD on.

What software are you using to drive this - Mach3? This will also need to be configured to generate the right signals from the BOB.
