Measuring between DCM (grounded) and the FOR pin I get 24V DC. So looks to me like the pin should be active low.

    I tried connecting DCM to FOR and there was no response. Not sure what I'm supposed to do?
    Ok you was correct but you need to Change parameter PD01=01. This tells the vfd to look for an external Run/Stop source using the Digital inputs.

    If you want to control the speed using 0-10v then you need to do the same to parameter PD02=01. Then connect upto ACM with Gnd(0v) and 10v to VI.
    -use common sense, if you lack it, there is no software to help that.
