1-10 Motor Construction
Option: Function:
[0] * Asynchron For asynchronous motors.
[1] PM, non-
salient SPM
For permanent magnet (PM) motors with
surface-mounted (non-salient) magnets.
Refer to parameter 1-14 Damping Gain to
parameter 1-17 Voltage lter time const. for
details about optimizing the motor
operation.
[3] PM, salient
IPM, Sat.
For permanent magnet (PM) motors with
interior (salient) magnets, with inductance
saturation control.

PM motor control
core are optimized for applications and inertia load in the
range of 50>Jl/Jm>5. Jl is load inertia from the application
and Jm is machine inertia.
For low inertia applications (Jl/Jm<5), it is recommended
that parameter 1-17 Voltage lter time const. is increased
with a factor of 5–10. Sometimes,
parameter 14-08 Damping Gain Factor should also be
reduced to improve performance and stability.
For high-inertia applications (Jl/Jm>50), increase
parameter 1-15 Low Speed Filter Time Const. and
parameter 1-16 High Speed Filter Time Const. to improve
performance and stability.
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.
1-14 Damping Gain

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.
