Namely DC braking function is invalid.
DC braking initial frequency in stop stage is what frequency when the
frequency inverter decelerate, frequency inverter will stop output and start
DC braking function. If the ouput frequency is less than the DC braking initial
frequency in stop stage while running, the frequency inverter will stop output
and start DC braking while stop.
DC braking time in start stage is the sustained time of the DC braking voltage
in the start stage; There is DC braking function in start stage only when
the parameter［E-30］choose"1". If braking time is 0.0 second, there
is not DC braking process.

E-41 Jump frequency 3
E-42 Jump frequency range
When frequency inverter runs with load, in order to avoid the output
frequency meeting the resonance frequency point of the mechanical load, user
can use the jump frequency. Frequency inverter can set three jump points to
execute the jumping. After setting the jump frequency, even if the given
frequency of the frequency inverter is on the resonance frequency point of the
mechanical frequency load, the output frequency of frequency inverter will
automatically be adjusted outside the resonance frequency point of the
mechanical frequency load to avoid operating in the resonance point.
