starting frequency, inverter does not ope rat e and is at st and-by st at e. The st art ing frequency value is not
res tricted by the lower limit frequency.
D uring FW D/REV swi tching, the starti ng frequency is inactive.
When it is being started, t he inverter firs t performs DC braking according to the set pri or-to-starting
DC braki ng current , and after the set pri or-to-s tarti ng DC braking time is passed t hen begins to perf orm
acceleration. If the se t DC braking time is 0, DC braki ng is invalid.
The bi gger the DC braking curre nt, the greater the braking force . The prior-to-starting DC braking
current i s t he perce ntage of the rated inverter current.
Beginning frequency of DC brake when stopping. During the Decel era ti on s top, when this fre quency
is reached, the DC brake is started.
Waiting t ime of DC brake when stopping: Prior to the DC brake, the invert er bloc ks the output, and
after this delay ti me, t he DC braking is st arted. It is us ed to preve nt over-current fault caused by DC
braking at hi gh s peed.
DC brake current whe n stopping: indicates the applied DC brake energy. The bigger the current, the
stronger the DC brake energy s hould be.
DC brake time whe n stopping: the durative time t hat the DC brake energy is appli ed. If the time is 0,
DC brake is i nvalid, and the i nvert er stops the motor based on the s et Deceleration time.
0: Deceleration stop
After the st op command is enabled, the inverter decreases the output frequency ac cording t o t he
Deceleration mode and t he defi ned Acceleration /Decel era ti on time , and the motor is s topped when the
frequency is 0.
1: Free-run stop
Once the stop command is val id, the inverter immediately ends the output. The l oading i s fre ely
