Fan Speed control to 10v Analog inverter input

[robmac 173]

Could this work to control an inverter motor control to give 4 fixed speeds?

Why dont you use RGBW module with pwm to 0-10V converter?

No reason other than I know about software not electronics.

Usually all inverters (VFD) have volt free inputs for at least 3 pre-set speeds that are set from their display. So you can use Fibaro relays to select which speed you need. Check the inverter manual for the connection circuit diagram, or post it here to tell you where to connect the relays.

dgcon,

 

It looks like you are correct from this diagram. 

 

 

also inverter is this one.

Check page 16 of the manual Parameters C37,C38 and C39 are pre-set speeds that you can set and then you need to configure the three inputs (E1,E2,E3 see page 14), to select theese speeds use the fibaro relays.

That is nice and simple thanks.
