Function:
The damping gain stabilizes 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
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
10% rated speed. Obtain quick
control through a short damping
time constant. However, if this value
is too short, the control becomes
unstable.
Function:
[ 0.01 - 20 This time constant is used above
10% rated speed. Obtain quick
control through a short damping
time constant. However, if this value
is too short, the control becomes
unstable.
Function:
[ 0.001 - 1 Reduce the influence of high
frequency ripple and system
resonance in the calculation of supply
voltage. Without this filter, the ripples
in the currents can distort the
calculated voltage and affect the
stability of the system.

data. The default value corresponds to
the nominal rated output of the unit.
Function:
NOTICE
This parameter cannot be adjusted
while the motor is running.
[ 20 - Select the motor frequency value from the
500 motor nameplate. For 87 Hz operation with
Hz] 230/440 V motors, set the value according to
the nameplate data for 230 V/50 Hz. Adapt
parameter 4-14 Motor Speed High Limit [Hz] and
parameter 3-03 Maximum Reference to the 87
Hz application.
Function:
[ 0.01 - Enter the nominal motor current
