For high load at low speed (<30% of rated speed), it is
recommended that parameter 1-17 Voltage lter time const.
is increased due to non-linearity in the inverter at low
speed.

The parameter stabilizes the PM motor to ensure
smooth and stable operation. The value of
damping gain controls the dynamic performance
of the PM motor. Low damping gain results in
high dynamic performance and a high value
results in a low dynamic performance. The
dynamic performance is related to the motor data
and load type. If the damping gain is too high or
low, the control becomes unstable.

High-pass lter 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 lter time
constant is used for reducing the
inuence
of high frequency ripples and
system resonances in the calculation of
machine supply voltage. Without this
lter,
the ripples in the currents can
distort the calculated voltage and aects
the stability of the system.
