:
Direct startup
:
When the DC brake time is zero, it starts at the startup frequency.
When the DC brake time is non-zero value, it can perform DC brake before start. It is suitable for the
applications where small inertia may cause reverse rotation at the time of startup.

:
Speed tracking startup
:
The inverter firstly judges the Speed and direction of the motor and then starts at the frequency
corresponding to the tracked rotation velocity of the motor, and performs smooth startup of the motor in
rotation without impact.It is suitable for the applications where large inertia is restarted due to transient
power shutdown.In order to ensure the performance of the rotation velocity tracking startup, motor
parameters (Group F1) should be set correctly.

:
Asynchronous pre-excitation startup
It is only valid for asynchronous motor , and is used to establish magnetic field before motor operation.
For pre-excitation current, pre-excitation time please refer to function code F6.05 and F6.06.
If pre-excitation time is set to 0, the pre-excitation process will be cancelled ,and start with start
frequency. If pre-excitation time is not set to 0, inverter first pre-excitation then starup. In this way, motor
dynamic response performance is promoted.

In order to complete the rotation speed tracking process in the shortest period, it can select the mode
of inverter tracking the rotation velocity of motor
:
0
:
Track downward from the frequency at the time of stop, which is generally selected at first.
1
:
Track upward from zero frequency, which is used when the inverter is restarted upon long period of
power shutdown.
2
:
Track downward from the maximum frequency, which is generally used for power generating load.

☆
In the mode of Speed tracking startup, it is used to select the speed of rotation tracking. The higher the
parameter value is, the faster the tracking velocity is, but too higher value may cause unreliable tracking.

★
To ensure the torque at the time of startup, proper startup frequency shall be set. In addition, in order
to set up magnetic flux when waiting for the startup of the motor, the startup frequency shall remain for a
certain period of time before accelerating to the setup frequency.
Start frequency F6.03 is not affected by the lower frequency limit.If the frequency reference value
(frequency source) is lower than the startup frequency, the inverter cannot start and will be in standby
status.
In positive&negative switching process, startup frequency retention time Yes not work.Startup
frequency retention time is not included in the acceleration time,but included in the simple PLC running
