First Analog Build - 7i97 - Anilam - Issue enabling machine

I am working on integrating my first analog servo build. 7i97 and Anilam drives. I am following the steps here . I have the encoder scaling correct but when I go to enable the machine, there is a brief moment of runaway before I get two errors: 
"joint 1 following error"
"could not switch the machine on. is limit switch activated?"

I am only working on joint 1 at the moment. 
No limit switches are in use at the moment. 

I have tried inverting 'output scaling' and 'encoder scaling' in every possible combination on the configuration page. 

Any suggestions? 

Thanks! 

Those are two separate issues, first is always (granted wiring is OK) hal/settings issue, the second is a limit switch triggered or inverted issue.
For the first, some checks:
-disconnect one of the analog output wires from mesa, power on the machine and enable shortly = the motor should very slowly turn. Be aware that if wiring is not OK the machine might run away at full speed
-reconnect the wires
-use a DVM set in beep or resistance mode and check between analog ground on the drive and machine ground = there should not be low resistance, usually. machine should be powered off.
-use the DVM and measure the analog output voltage on Mesa or on the drive while LinuxCNC is disabled but the machine is powered on and LinuxCNC is running = there should be no voltage
-
-use the calibration screen to invert the output, or encoder, but NEVER both, test by enabling the machine
-if you still get joint errors, lover the P value to 10 or 5 or 2 and test.

You MUST set the 7I97 PWMgens offset mode to true or runaways are guaranteed.

Yep, that fixed everything! Thanks a million! 

For those who run into this in the future, I needed to add to each axis definition in the .hal:

Where "xx" = joint number. 

Now the machine is stable and jogging smooth and silently. Beauty.
