0: Start directly
Start with the set start frequency (P03.06) and start frequency hold time (P03.07).
1: First brake then start
First DC injection brake (Refer to P03.08
、
P03.09), then start with mode 0.
2: Catch a spinning motor start
Automatic tracking the motor speed and direction, the running motor can start smoothly
without impact.

Enable this mode could allow the drive could track the DC link very quickly, especially
useful the low solar power.
How it works is shown below:
If the DC bus voltage is below V
ml
, the drive will decelerate according to deceleration rate
(P12.21). When the running frequency is zero, block IGBT.
If the DC bus voltage falls to V
uu
, the drive will initiate a F003 trip, as shown in the following
figure 4-3-a.
If the DC bus voltage is over V
uuRst
, the drive will accelerate to the reference frequency
according to the setting acceleration rate, as shown in the following figure 4-3-b.
