11.9 F07 Group: Operation Control
F07.0x group: Start control
The drive can select 3 starting modes, according to the starting frequency starting mode, DC braking starting mode and speed tracking starting mode.

0: started by the start frequency
In this mode, the output frequency changes directly from F07.02 [starting frequency] according to the acceleration time.
1: After DC braking, start again by starting frequency
In this mode, first press F07.20 [start DC braking current], F07.21 [start DC braking time] to perform DC braking, and then start according to the starting
frequency. Applicable to the field where the motor speed is required to be zero or lower at start-up, first give the motor a braking force and then start.
2: Speed tracking start
First detect the speed and direction of the motor, and then start according to the detected speed. Suitable for on-site quick start after large inertia load
shutdown.
Note:
When the starting frequency is less than F7.02 [starting frequency] at startup, the drive will not start, it will be in standby state, and the running
indicator will light.
The S/T2 model does not support the speed tracking start.

Start pre-excitation time
STOP
Under the asynchronous motor vector, pre-excitation before starting can effectively improve the starting performance of the motor and reduce the starting
current and starting time.
Note:
When the default is 0.00s, the actual time of starting the pre-excitation is automatically calculated according to the motor parameters.
The S/T2 model does not support pre-excitation before starting.
