I've had a hectic few months with work but I've finally got a break in my schedule to dedicate the next 2 weeks to getting this machine up and running. I managed to take out the previous configuration of the x axis stepper motor and now instead of the the x axis stepper motor being on top of the gantry its fixed securely inside now with the full four bolts. On doing so I noticed one of the cogs had damaged teeth and had to get a new one made.

Last night I had a couple hours free so I thought foolishly that I could get the VFD setup with mach 3 in this time. Anyway I followed the manual here http://www.omc-stepperonline.com/dow...ers_Manual.pdf but I wasnt entirely sure with the setup coming out of the VFD ASKPOWER A131 as all I could find were these instructions http://www.instructables.com/id/6-Ax...reak/?ALLSTEPS

The spindles runs from the panel fine. All and any help is appreciated thank you in advance

Ok this is easy to make happen but will require you changing some parameters in the VFD so you'll need the manual.

If you can find the VFD manual I can describe how to do it. What you want to know is the Parmeter number for External frequency control for the Speed control. Also parameter for ON/OFF so can set to External control.
On the Huanyang VFD's which this looks like but Isn't then it's parameter 01 & 02

Hi Jazz on wiring I had FWD going to PIN 17 and and D2 JOG going to PIN 14 with 10V IN & GND going to the right hand side of the bob as shown in the linked BOB manual above. I've uploaded the VFD manual. Thanks for your help.

Run wire from the FWD to the Relay Output on the Bob and back to Gnd on VFD. Then Set PN04 = 2. This will take care of ON/OFF provided you Enable the output in mach3 and assign the output number in Spindle setup.

For speed control you need to take the 10V from BOB to 10V-IN on VFD. 0V form BOB to Gnd on VFD. Set PN03 =4.
This will take care of Speed control provided you set it up correctly in mach3.

To be honest Don't like the fact the Analog 0v doesn't appear to be islolated from common Gnd but your stuck with that I suppose.
