MIN_FERROR = 0.010 - This is the value in machine
units by which the axis is permitted to deviate
from commanded position at very low speeds. If
MIN_FERROR is smaller than FERROR, the two produce
a ramp of error trip points. You could think of
this as a graph where one dimension is speed and
the other is permitted following error. As speed
increases the amount of following error also
increases toward the FERROR value.

FERROR = 1.0 - FERROR is the maximum allowable
following error, in machine units. If the
difference between commanded and sensed position
exceeds this amount, the controller disables servo
calculations, sets all the outputs to 0.0, and
disables the amplifiers. If MIN_FERROR is present
in the .ini file, velocity-proportional following
errors are used. Here, the maximum allowable
following error is proportional to the speed, with
FERROR applying to the rapid rate set by
[TRAJ]MAX_VELOCITY, and proportionally smaller
following errors for slower speeds. The maximum
allowable following error will always be greater
than MIN_FERROR. This prevents small following
errors for stationary axes from inadvertently
aborting motion. Small following errors will
always be present due to vibration, etc.
