    No not quite, unless ACM and DCM are the same on your VFD Drive which you would have to check with a meter if they are the same then you are good to go, but normally VI and ACM are the connection for your speed control and FOR and DCM for the relay ON / OFF control

    VI and ACM

    FOR and DCM

    Sorry looking back I ment to break the acm-dcm ground bridge from the manual pic.

    So if I run those straight I should be good?
    Would running analog freq (P1) to AI be better than 0-10v to VI to control the spindle speed? TIA.

    Most don't bother to even try the AI connection as they don't have the output for it, if the 0-10v does not work then you could try it, there would not be any difference, both will do the same job
