F04.00=0: Start Directly
Inverter starts with DC brake (not available if F04.04=0), conducts the pre-excitation
(not available if F04.07=0), starts at the start frequency, and enters the set frequency
running after the retention time of the start frequency.
F04.00=1: Rotation Speed Tracking Start
Inverter will first perform the rotation speed tracking (size and direction) at startup,
and start up smoothly from the actual rotation frequency of present motor

Set an appropriate start frequency, in order to guarantee motor torque at start. In
order to enable motor to make magnetic flux fully, it’s required to maintain motor’s start
frequency for certain time. The start frequency F04.01 is not limited by the lower limit
frequency.

Before inverter starts, motor may run at low speed or reverse. Starting inverter at
this time immediately may result in overcurrent fault. In order to avoid such a fault, add
the link of DC brake at first prior to inverter start to stop motor, and then start inverter to
the set frequency according to the set direction.
Different values of F04.03 may realize different start DC brake torques.
By setting the action time of DC brake through F04.04, inverter starts immediately
