0: Direct start
If DC braking time is set to 0, the inverter will start from the start frequency.
If DC braking time is set to nonzero value, DC braking will be performed firstly, then the inverter starts from
the start frequency. It is suitable for the application that the motor maybe running during starting with small
inertia load.
1: Speed tracking and restart
Inverter detects the rotation speed and direction of motor, and then starts to run at the detected speed and
direction. This can realize smooth start of running motor with big inertia load when instantaneous power-off.
To ensure the performance of speed tracking restart, please set motor parameters accurately. (Group P1)
2: pre-excitation start
Only valid for asynchronous motor, used to establish magnetic field before motor running. For
pre-excitation current, pre-excitation time, please refer to P6-05, P6-06 instruction.
If pre-excitation time is set to 0, the inverter will cancel the pre-excitation process, start from the starting
frequency. Or the inverter will make the pre-excitation, then start, which can improve the motor dynamic
response performance.

No output
1
With output
The inverter output mode when the running frequency is 0Hz, this function is only valid for VF control.
0: When the running frequency is below a certain frequency, inverter doesn’t output. Usually this mode is
selected.
1: Inverter outputs at any running frequency.
