getting start, which suits for the applications where reverse rotation is likely to occur
when small loads are getting start
1: Speed tracking restart
First of all, the inverter makes an estimate of motor speed and direction, then starts
at the frequency in accordance with the tracked motor speed. the rotating motor is
running smoothly without surge.
It is suitable for the restart upon transient power failure of large loads.

0: to track from the frequency on power failure, generally, it selects this mode.
1: this mode is used to track from zero frequency and restart after a long period of
power supply off .
2: This mode is used to track from the maximum frequency, and is suitable for the
general power generating loads.
