Asynchron
For asynchronous motors.

SPM
For permanent magnet (PM) motors with

improve performance and stability.
For high load at low speed [<30% of rated speed] it is
recommended that

is
increased due to nonlinearity in the inverter at low speed.
1-14 Damping Gain
Range:
Function:
120
%
*
[ 0 -
250
%]
The parameter stabilises 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.
1-15 Low Speed Filter Time Const
Range:
Function:
Size related
*
[ 0.01 -
20 s]
High pass-filter 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 gets
unstable. This time constant is used
below 10% rated speed.
