General Mach Discussion / Speed control of spindle through my bob

Hi There
First of I would like to Congratulate the Mach3 people for their most wonderful software also thank this forum, for giving me the opportunity of placing my question here.
I need help on the issue of controlling the speed of my Spindle through my Bob.
I am putting together a wood cutting 3 axis CNC Machine.
I am using a typical so called 5 axis Popular Chinese Bob of which, I am attaching a supporting Docs.
Also I am using a 3 Hp., LS Inverter,  Plus a Single phase 3 Hp Spindle of which I am also attaching the supporting docs.
Also I am using Mach3 Version R3.041.
Finally a 24 VDC 20 amp Power supply.
I managed to run My step Motors, Emergency Switches and limit switches …, and all is fine, I can also stop and Run my spindle through the Bob.
But I just cannot control the speed of it. Any recommendation is greatly appreciated.
I think I am doing something wrong in my Mach3 Settings, because the Inverter and bob Connection is very straight forward, and I am attaching the V1 from spindle to the 0-10 Volt of my Bob, and com to Gnd of the Bob(Top Row Terminal Of my Inverter, from the picture), similar to my stop and run(Bottom Row Terminal Of my Inverter).
Regards
