Here is the full manual for the VFD:

if anyone has time I would appreciate you checking it.

from what I understand:

there are function pins (X1-X8) that can be programmed for multiple functions but default is shown in the diagram showing:
X1 - forwrad start
X2 - reverse start
X3 - stop

so if I can get the right way to hook into these I think it will work.

but also in the manual it states we have to change some default settings to allow controlling start/stop and frequency from outside.

but what I don't understand in general is the need for relays, maybe someone with electronics experience can explain it, isn't it possible to just hook the pins coming from BOB to the inverter input ? unless the relays give a higher voltage?

I understand how relays work (a bit lol) but was wondering how they are functioning in the C6 ( are they outputting 12v being controlled by 5v) ?


anyways thanks for reading and hope someone is bored enough to open the manual and read through! haha
