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.

Multi-Stepping™ is similar to dynamic smoothing™ except that it is a much
more aggressive 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.
