Function:
For asynchronous motors.
For permanent magnet (PM) motors with
surface-mounted (non-salient) magnets.
Refer to parameter 1-14 Damping Gain to
parameter 1-17 Voltage filter time const. for
details about optimising the motor
operation.
For permanent magnet (PM) motors with
interior (salient) magnets, without
inductance saturation control.
For permanent magnet (PM) motors with
interior (salient) magnets, with inductance
saturation control.
Function:
The damping gain stabilises the PM machine. The
value of damping gain controls the dynamic
performance of the PM machine. High damping
gain gives high dynamic performance and low

Function:
damping gain gives low dynamic performance.
The dynamic performance is related to the
machine data and load type. If the damping gain
is too high or low the control becomes unstable.
Function:
[ 0.01 - 20 This time constant is used below
s] 10% rated speed. Obtain quick
control through a short damping
time constant. However, if this value
is too short, the control becomes
unstable.
