Advice sought on programming and controlling a VFD

Now that I'm done with the major phase of my Bridgeport conversion
and the interfacing to MACH2, the time has arrived to break out the
installation manual for my VFD.

Environment:

The drive is an Omron IDM (same as Yaskawa) G5+ and the book is about
a million pages long documenting it's options.

I've built a board up with the VFD (3HP size, but my motor is 1.5HP
running 3 phase 220 volts), a line reactor, a load reactor, an EMI
filter on the line, a couple of ferrite cores and a breaking resistor.

MACH2 will control the speed by using a Digispeed to convert from PWM
to analog voltage.

My BP has a reversing starter (which will be excessed) and a regular
starter (which I will probably set up to control the power to the VFD
using the original Start/Stop button). I figure the power should
stay on to the VFD during all operations so that the braking resister
will do its job.

Any guidance or advice about how to handle the million options and
control wiring would be appreciated.

Happy New Year,
Jeff
