Used to establish the magnetic field before the motor runs. For the pre-excitation current and time, please refer to
the description of parameters 07-03 and 07-04.
If the pre-excitation time is set to 0, the inverter cancels the pre-excitation process and starts from the startup
frequency. If the pre-excitation time is not 0, pre-excitation first and then start, can improve the dynamic response
performance of the motor.

The inverter starts to run from the startup frequency (07-01), after the startup frequency holding time (07-02), then
accelerates to the target frequency according to the set acceleration time.
The startup frequency 07-01 is not limited by the lower limit frequency. However, when the set target frequency is
less than the startup frequency, the inverter does not start and is in a standby state.
During the switching between forward and reverse rotation, the startup frequency holding time has no effect. The
startup frequency holding time is not included in the acceleration time, but included in the running time of the
simple PLC.

Startup DC braking is only effective when the starting mode is direct start. At this time, the inverter performs DC
braking according to the set startup DC braking current, and then starts running after the startup DC braking time.
If the DC braking time is set to 0, DC braking is invalid.The greater the DC braking current, the greater the braking
force.
If the startup mode is asynchronous motor pre-excitation start, the inverter first establishes the magnetic field
according to the set pre-excitation current, and then starts running after the pre-excitation time.
If the pre-excitation time is set to 0, the pre-excitation is invalid and starts directly.
The startup DC braking current/pre-excitation current is a percentage of the rated current of the inverter.

0: Decelerate to stop after the stop command is valid, the inverter reduces the output frequency according to the
deceleration time, and stops after the frequency drops to 0.
1: After the coast stop command is valid, the inverter immediately terminates the output, and the motor coasts to
stop according to the mechanical inertia.
