It adjusts the
inverter’s capacity in
suppressing the stall
over voltage. The
bigger the value is,
the stronger the
suppressing capacity
is. For the load with
small inertia, the
value should be
small. Otherwise, the
dynamic response of
the system will be
slow. For the load
with large inertia, the
value should be
large. Otherwise, the
suppressing result
will be poor, and over
voltage fault may
occur.
