Hello,
I am new to the forum I am from Costa Rica and i need some help connecting my vfd to my acorn.
I have checked the diagram for generic vfd but looking at mine I am not sure how to connect it.
I have attached some pictures of the control ports for reference.
Any help is much appreciated.
Best regards

Re: HELP Connecting acorn to Eurotherm VFD
Try these:
Acorn ANGND to VFD term 1
Acorn AN OUT to VFD term 2
VFD Term 6 to a relay common That relays NO terminal to VFD terms 7 and 8 If only using CW rotation (as SPINFWD)
If CCW is required then VFD term 6 to a second relay common with relay NC term to VFD term 8 ( as SpINREV)
