Connect the VFD ACM (analogue ground) to your 0V/GND level, and the AXBB analogue AO1 output to VI input to the VFD. That gives you your 0-10V control.
Now, I expect O2 and O3 outputs are designated forward/reverse, so connect these to the FOR and REV inputs to the VFD. As these are digital inputs to the VFD you'd best connect the DCM (digital ground) to your 0V/GND as well.
You say you've set PD00... : so I guess you've unlocked PD000, PD001 = run control = external = 1?, PD002 = operating freq = external = 1, PD044 = FOR = 2, PD045 = REV = 3, PD070 = 0-10V = 0 etc?Last edited by Doddy; 14-09-2019 at 10:39 AM.
