set in F2.04 for DC braking and
then start from the start
frequency.
2: Speed tracking and restart:
Track the current speed and
direction of the motor, and
perform smooth start without
impact on the motor that is still
rotating.
LED tens digit: Speed tracking mode
0: Track down from the frequency of
shutdown, usually this method is
used.
1: Track down from the maximum
frequency, suitable for power
generation load.

1. The start frequency refers to the initial
frequency of the drive at start. As shown
in fs in the figure, setting a proper start
frequency can increase the torque at start.
2. Within the hold time of the start
frequency, as shown as t1 in the figure,
the output frequency of the drive is the
start frequency, and then operate from the
start frequency to the target frequency.
3. The start frequency value is not limited
by the lower frequency limit.
