I'd be willing to bet that the problem with freqmod is a miss match between
input scale and output scale in the ini file.  With freqmod, you need the
same value in both variables.  They can be different for each axis but need
to be the same within an axis.

INPUT_SCALE =                   1000    0
OUTPUT_SCALE = 1.000   0.000

This is the way they look in the stock ini file and they will work with
steppermod.  To make them work with freqmod you would need to change them
to 

INPUT_SCALE =    1000    0
OUTPUT_SCALE = 1000    0.000

Since these will be rewritten by the running EMC when it errors or closes
down you may see zeros after the decimal point but it is the value of the
numbers that is important.

When you get the EMC hooked up to a machine, you will need to change these
values to match the number of pulses per inch (US) that works for your
axis. 

I have not done this but when you get to stepper motors with quad feedback
from a Kulaga/Mauch type board then you will use smdromod and can change
the values to match pulse train out with input scale and pulse train return
with output scale.
