You don't say which parameter this is? If it is MAX_VELOCITY than you
are set to 60 IPM if you are using inches.

Wrong. You say you are using half step (5X pulse multiplication) so you
really have 400 steps per rev.

2:1

So you have 400 steps per motor rev X 2 = 800 steps per screw rev. Then
you have X 10 or 8000 steps to get one inch of travel. So your
INPUT_SCALE and OUTPUT_SCALE need to be set to 8000 for Freqmod.o. If
you set the drives to fullstep it will be 4000 and if you set it to 10u
it will be 16000
