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.
The startup frequency (P6.03) is not restricted by the frequency lower limit. If the set target
frequency is lower than the startup frequency, the Inverter will not start and stays in the standby state.
During switchover between forward rotation and reverse rotation, the startup frequency holding
time is disabled. The holding time is not included in the acceleration time but in the running time of
simple PLC.
Example 1:
P0.03 = 0 The frequency source is digital setting.
P0.08 = 2.00 Hz The digital setting frequency is 2.00 Hz.
P6.03 = 5.00 Hz The startup frequency is 5.00 Hz.
P6.04 = 2.0s
The startup frequency holding time is 2.0s.
In this example, the Inverter stays in the standby state and the output frequency is 0.00 Hz.
Example 2:
P0.03 = 0 The frequency source is digital setting.
P0.08 = 10.0 0 HzThe digital setting frequency is 10.00 Hz.
P6.03 = 5.00 Hz The startup frequency is 5.00 Hz.
P6.04 = 2.0s
The startup frequency holding time is 2.0s.
In this example, the Inverter accelerates to 5.00 Hz, and then accelerates to the set frequency
10.00 Hz after 2s.

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 = 3), 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.
The startup DC braking current or pre-excited current is a percentage relative to the base value.
