CNC Rebuild Wiring Diagram Version 1

Below is a first shot at my CNC machine rebuild wiring diagram.  It contains a C11S parrallel port breakout board from CNC4PC.  3 KL-9082 Stepper Motor Drives from Keling. An Allen Bradely VFD drive to provide variable speed to the spindle driver.  I am controlling incoming power to the VFD with a relay.  The coil will power from the system 'master power'.  The enable input on all drives and the breakout board will be de-energized using an E-Stop.  Not sure about this configuration yet.  Diagram does not show any limits yet.

VFD Spindle Drive

My new mill has a 3 phase spindle motor.  I cannot get 3 phase where I live (without significant expense).  I looked into using a 7.5HP 3 phase motor I already have to create a rotory phase converter.  They sell pre-assembled 'control panels' which include capacitors and relays required to produce 3 phase power when wired to a motor.  While looking at these panels I came across an Allen Bradley VFD which can use single phase source to drive a 3 phase motor.  In addition to this conversion it will allow the ability to control spindle speed electronically.  After some research and shopping I purchased a Allen-Bradley 22F-A011N103 VFD for $125.  This unit should allow easy connection to my new PC Based CNC System (Software: Mach 3).  Many of the 'breakout boards' for PC CNC controls have a 0-10VDC speed control output and a dual relay configuration that can automatically activate using only two pins.. See preliminary wiring diagram.

Tri-onics Handyman CNC Knee Mill

Purchased an older 'CNC' mill.  The unit functions manually (if I had 3 phase power) and the CNC portion was considered non-functional.  Plan is to re-enable the cnc through pc control.
