Parameter Descriptions 12-49
Enables/disables the function which allows the drive to start into a
spinning motor at actual RPM when a start command is issued.
Normally, 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.
Adjusts the responsiveness of the flying start function. Increasing
the value in this parameter increases the responsiveness of the
flying start function.
