The default control parameters for VVC
core are optimised for HVAC applications and inertia load
in range of 50>Jl/Jm>5, were Jl is load inertia from the
x
application and jm is machine inertia.
For low inertia applications Jl/Jm<5 it is recommended
x
that 1-17 Voltage filter time const. is increased with a factor
x
of 5-10 and in some cases 1-14 Damping Gain should also
be reduced to improve performance and stability.
x
For high inertia applications Jl/Jm>50 it is recommended
x
that 1-15 Low Speed Filter Time Const., 1-16 High Speed Filter
Time Const. and1-14 Damping Gain are increased to
x
improve performance and stability.
x x
For high load at low speed [<30% of rated speed] it is
x x
recommended that 1-17 Voltage filter time const. is
x x
increased due to nonlinearity in the inverter at low speed.

SPM surface mounted (non salient) magnets.

Function:
[ 0 - The parameter stabilises the PM motor to ensure
250 smooth and stable operation. The value of

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.

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
