High-pass filter damping time constant
determines the response time to load
steps. Obtain quick control through a
short damping time constant. However,
if this value is too short, the control
becomes unstable. This time constant is
used below 10% rated speed.

Machine supply voltage filter time
constant is used for reducing the
influence of high frequency ripples and
system resonances in the calculation of
machine supply voltage. Without this
filter, the ripples in the currents can
distort the calculated voltage and
affects the stability of the system.
