compensa-
tion gain
(speed cal-
culation)
Operation restarts at a speed
obtained by multiplying the
speed from the speed search by
the compensation gain (excita-
tion search only.)
Increase this setting if over-
voltages occur when a speed
search is performed after a
long baseblock, for example, in
searches at startup.

Propor-
tional gain
of the speed
estimator
during
speed search
Sets the proportional gain (PI
control) of the speed estimator
during speed search taking the
setting of N4-08 as equivalent
to a setting of 1.0.
Usually, there is no need to
change this setting. If, how-
ever, the load inertia is large
and overvoltages occur during
the search, reduce this setting.
Increase this setting for greater
speed coincidence response.
