In the vector control mode
,
the output of the speed loop regulator is torque current
reference
.
This
parameter is
used to
flter
the torque references
.
It
need not
be adjusted
generally
and
can
be
increased
in
the
case
of
large
speed
fuctuation
.
In
the
case
of
motor
oscillation
,
decrease
the
value
of
this
parameter
properly
.
If the value of this parameter is small
,
the output torque of the AC drive may fluctuate
greatly
,
but
the
response
is
quick
.

During deceleration of the AC drive
,
over
-
excitation control can restrain rise of the bus
voltage
to
avoid
the
overvoltage
fault
.
The
larger
the
over
-
excitation
gain
is
,
the
better
the
restraining
effect
is
.
Increase the over
-
excitation gain if the AC drive is liable to overvoltage error during
deceleration
.
Too large over
-
excitation gain
,
however
,
may lead to an increase in output
current
.
Therefore
,
set
this
parameter
to
a
proper
value
in
actual
applications
.
Set
the
over
-
excitation
gain
to
0
in
applications
of
small
inertia
(
the
bus
voltage
will
not
rise
during
deceleration
)
or
where
there
is
a
braking
resistor
