Dynamic Smoothing is a temporal filter ( 2nd- Order, Low-pass) applied
to the command sequence to reduce jerk. It helps reduce overshoot and
lessens the excitation of mechanical resonance in the system. It filters
from slightly below the resonant frequency up to well above resonance to
remove spectral content would be misrepresented in the motor output and
may also excite other parts of the machine.

EDUCTION
Reduces Drive and Motor heating by invoking Standby Current
Reduction via Switch S2-10. When enabled, the reduction mode cuts
motor current to 75% of its commanded value 100 ms after receipt of the
last step pulse or the end of a stored move. The reduction proportion and
the delay can be set to other values using P7000Tools.

MultiStepping™ is similar to Dynamic Smoothing™ except that it is a
much more agressive use of the filter. Typically, it results in a filter that
begins to roll off a couple octaves below the resonant frequency. This is
intended for use with course resolution (full/half step input pulses) to
smooth out the big steps into a continuous train of microsteps.
