Fig.4-9 Speed track then start
Note: (1) Starting mode 0: It is recommended for general application or when the inverter drives synchromous motor.
(2) Starting mode 1: It is suitable for small inertial load that motor will forward or reverse rotate without load and it
is not recommended for big inertial load.
(3) Starting mode 2: It is suitable for motor startin during free stop or restarting after instantaneous power off.
P2.01
Starting frequency
Range: 0.20~20.00Hz
0.50 Hz
P2.02
Lasting time of starting frequency
Range: 0.0~30.0S
0.0S
Starting frequency points to the initial frequency when inverter starts; see Fig.4-10 Fs. Lasting time of starting frequency
points to the time while inverter is running at the starting frequency, see Fig.4-10 t
1.
Note: Starting frequency is not limited by the lowest frequency.

P2.03
DC brake current when starting
Range: 0~80(%)
0(%)
P2.04
DC brake time when starting
Range: 0.0~60.0s
0.0s
When P2.00 =1, P2.03 and P2.04 are valid, as shown in Fig. 4-11.
The setting of DC brake current is the percentage of rated current. When the starting DC brake time is 0.0s, there is no DC
brake process.
