First have you enabled the Spindle and set Analog output pin in the plug-in. Until this is done you won't be able to control the speed.
In the plug-in there is also a setting for Acceleration/deceleration set this to 24000.
You will also need to set the pulley speeds in Mach3 and setup the spindle in ports & pins.

Also check the VFD accepts 0-10v and not 0-5v. Some VFD's can be set to use either.
