Spindle Configuration

Hello all, I am retrofitting a Cincinnati Arrow 1000. I am running Linuxcnc 2.8 and Linux Mint. I am hitting a wall getting the spindle running. The hardware I have in place is 7i92H/7I77/7I71/7I70 and 7i73. I have all the axis tuned and moving precisely and now working on the spindle I cant figure out how to calibrate. The spindle drive is a vickers VFS5 and unless I am mistaken it takes an analog signal to dictate the spindle movement. I have tried examples in the book with DAC scaling and they dont seem to work. I also started putting in the PWMgen functions but quit midstream for fear of messing something up. It is probably something I have configured wrong. Also when the spindle is enabled it drifts slightly. I have tried adjusting the PID loop and it doesn't seem to help. Any ideas to make this happen would be appreciated. Ultimately I would like to have this spindle closed loop so I can do rigid tapping and toolchanges with the carosel. Enclosed are the HAL, INI and Custom.hal files where all of my coding has been performed.

Thanks for your help in advance.

One basic error is that you have the spindle connected to analog out 4
It should be connected to analog out 5 (the channel with the separate enable)

Thanks for the replies in the past, I am going to try to resurrect this now that I have some time to mess with it. 
Like I said before I am trying to control the BDS5 spindle drive that came with the machine. I corrected the analog out to 5 and my machine has an output that kicks the spindle in CW/CCW rotation which enables the spindle.  Here is a pic of the wiring diagram that came with the machine. I am able to control the spindle up/down with the manual toggle buttons but when commanded via MDI it faults the drive.  I need to get a ramp in place that can smooth the transition from 0 to speed.  Is there an example of code that I can use to get this in place? 

Hey all, I have been messing around with this some more and I think I may have it pretty close.  For some reason, the commanded spindle speed ignores the ramping actions and the commanded speed is almost instantaneous. This VFS5/BDS5 drive behaves pretty much an axis drive but accepts +-10V for commands. If I can get this to soft start to work I think I can avoid the drive faulting and I can start working on the toolchanger. That piece should be pretty good since this drive orients with an only an input pin. 

Can a seasoned veteran of linuxcnc look over my code below and let me know if I am missing something.
