When power on after power off, if it meets the starting condition, after a period of time defied by FC.15, the VFD will
start automatically in speed tracking method.

Start frequency is the initial frequency when the VFD starts, as fs showed in the following figure. For some system with
relatively big starting torque, a reasonably set start frequency can solve effectively the hard starting problem. The
retention time of start frequency is the time VFD stays in the start frequency value during starting stage, as t1 showed in
the following figure.

Notice
：
1.Start frequency is not effective by lower limit frequency. Jog frequency is not effective by lower limit frequency but is
restricted by start frequency.
2.When F0.18=1 (high frequency mode), start frequency has a upper limit of 500.0Hz.
