F1.01 Starting frequency Range: 0.0－10.00Hz 0.00Hz
F1.02 Starting freq. duration time Range: 0.0－20.0S 0.0S
Starting frequency means initial frequency at which the inverter start up，as fs
shown in Fig.6-6；Starting freq. holding time means consecutive run time during
which the inverter run at starting frequency，as t
1
shown in Fig.6-6.
Fig.6-6 starting freq. and starting time
F1.03 DC braking volt. when starting Range: 0－15(%) 0(%)
F1.04 DC braking time when starting Range: 0.0－20.0S 0.0S
When F1.00=1，F1.03, F1.04 is effective，as shown in Fig.6-7.
F1.03 is percentage relative to inverter rated input voltage. Have no DC braking
process when starting DC braking time is 0.0.
Starting frequency is not limited by low limit frequency.

(1) Start-up mode 0: Advise the user to adopt start-up mode 0 in common application occasion .
(2) Start-up mode 1: Be applicable to small inertia load with forward run or reverse run
phenomena when the motor doesn’t drive any device, for big inertia load, advise not
to adopt start-up mode 1.
(3) Start up mode2: Be application for big inertia load haven’t firm stopped start, usually
cooperate with restart after power lost, fault recovery function and so on. Please
notice the following two points before use the start.
A. Wait few seconds to restart after inverter free stop. If turn out over current fault in
start process, please extend restart time.
B. Don’t revise frequency in speed check process, otherwise it will alarm.
