V5 series inverter
58
Inverter starts at the starting frequency (P2.01) within the lasting time of starting frequency (P2.02).
1: Brake first and then start from the starting frequency
Brake with DC braking current (P2.03) within braking time (P2.04) and then start at starting frequency.
2: Track the speed then start
When P2.00=2, it is valid for repowering after instantaneous power off or restarting after external fault. As shown in
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 no driving but there is forward or reverse rotation,
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.

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.

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.
