To ensure the motor torque at inverter startup, set a proper startup frequency. In addition, to
build excitation when the motor starts up, the startup frequency must be held for a certain
period.

Startup DC braking is generally used during restart of the inverter after the rotating motor stops.
Pre-excitation is used to make the inverter build magnetic field for the asynchronous motor
before startup to improve the responsiveness.
Startup DC braking is valid only for direct start (P6-00 = 0). In this case, the inverter performs
DC braking at the set startup DC braking current. After the startup DC braking time, the inverter
starts to run. If the startup DC braking time is 0, the inverter starts directly without DC braking.
The larger the startup DC braking current is, the larger the braking force is.
If the startup mode is pre-excited start (P6-00 = 2), the inverter builds magnetic field based on
the set pre-excited current. After the pre-excited time, the inverter starts to run. If the
pre-excited time is 0, the inverter starts directly without pre-excitation.

★
Used to set the frequency change mode during the AC drive start and stop process.
0: Linear acceleration/deceleration
The output frequency increases or decreases in linear mode.SV600 series inverter has four
group of Acc./Dec. time, which can be selected by multi-function terminal DI. For the settings,
please refer to group P4 parameters.
1: S curve acceleration/deceleration A
The output frequency increases or decreases along the S curve. This mode is generally used in
the applications where start and stop processes are relatively smooth, such as elevator and
conveyor belt. P6-08 and P6-09 respectively define the time proportions of the start segment
and the end segment.
2: S curve acceleration/deceleration B
