Ok, it actually works with spindle-ramp! So in my case I don't have any feedback from spindle or vfd (VFD has its own accel/decel future), so I adjusted spindle-ramp.maxv parameter the way it is "delayed" for 1-2sec just to be sure vfd has reached target rpms. Also practical, to have visual "feedback" on pyvcp meter and led for spindle-at-speed.
