reconnects to a spinning motor at actual
RPM when a start command is issued.

“Enabled”
When a drive is started in its normal mode, it initially applies a frequency of 0 Hz
and ramps to the desired frequency. If the drive is started into an already spinning
motor in this manner, without Flying Start enabled, large currents will be
generated and an overcurrent trip may result.
In Flying Start mode, the drive's response to a start command will be to identify
the motor's speed and apply a voltage that is synchronized in frequency,
amplitude and phase to the counter emf of the spinning motor. The motor will then
accelerate to the desired frequency.
170 [Flying StartGain]
Sets the response of the flying start
function.
