Hello,

I need to connect my VFD (PRT-E1500W) to my BOB (ST-V2). These are built into a CNET 6040.

The connection I'm struggling with is the one marked AVI on the VFD. On the original BOB I had a terminal also marked AVI, so simple connection. The new new BOB has no AVI terminal, however it has two terminals marked PWM. I understand the one on the right hand side of the BOB is for digital VFD's, where as the bottom PWM is for analogue. If this is true, can I connect the analogue terminal to the AVI terminal on the VFD? Or am I way off?

There's loads of information out there for the stepper drives and limit switches to the BOB, but not VFD's

Hopefully the knowledge on here can help me, thanks

Here is a link to BOB with the same layout - https://www.omc-stepperonline.com/download/ST-V2.pdf
This is the only info I can find on the VFD - https://madexp.com/wp-content/uploads/2018/01/PRT-E1500W-.pdf

Sorry, I got the PWM ports the wrong way round. The right hand is 0-10V analogue and the bottom is PWM digital.
