Connecting VFD (PRT-E1500W) to BOB (ST-V2)
« on: January 19, 2022, 03:22:53 PM »
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.
