CNCEST 6040 VFD rewire to ST-V2 board help

[Hulksmash]

Need to see the ST-V2 manual do you have a link.?

I've got a feeling that the board uses a common Gnd not an isolated Gnd for the Analog output. In which case I wouldn't use it.

Could you recommend an alternative low cost one if I cant use this too please.

Part of me thinks to just buy a cheap VFD - got to be better than one in the machine

Hello,

Have you got this sorted as I have the same issue? I too have a CNET 6040

Just to recap my issue, I'm trying to connect my VFD (PRT-E1500W) to my BOB (Manual/book shown here - https://www.omc-stepperonline.com/download/ST-V2.pdf).

I've not had conformation of this yet, apparently the PWM on the right of the BOB is for Digital VFD, where as the PWM terminal on the bottom row (4th from the right) is for analogue VFD. Can anyone confirm this please, as I understand the bottom terminal could be connected to the AVI terminal of the PRT-E1500W.

I'm currently comfortable with all the other terminals.

Thanks in advance of moving this issue forward.

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