Name
Description
Display
Sets the amount of time the
Drive will dwell at E1-09
(Minimum Frequency) at the
end of deceleration. If this
time is set too low, the
machine inertia can cause the
motor to rotate slightly after
the HSB stop is complete and
the Drive output is shut off.
Sets the time required for an
HSB overload fault (OL7) to
occur when the Drive output
frequency does not change for
some reason during an HSB
stop. Normally this does not
need to be adjusted.

Description

speed estimator for PI
control.
Set the proportional gain of
the speed estimator for PI
control.
Sets the P-gain on the hi-
speed side of the Observer (PI
Controls). Operates at the
same proportional gain as
N4-07 when set to zero.
Sets the switching frequency
for the high and low speed
Observer.
Use a large setting if load
tolerance needs to be
increased during low-speed
regeneration. If the setting is
too high, then torque
command monitor and the
actual torque system will be
weakened.
