Regardless of the value applied by the reference signal, the output speed applies the setting of the
start speed in par. 1-74 or par. 1-75 and the output current corresponds to the setting of the start

Function:
This function makes it possible to catch a motor which is spinning freely due to a mains drop-out.
Flying Start
When par.1-73 is enabled, par. 1-71
Search direction for flying start is linked to the setting in par.4-10
Clockwise
[0]: Flying start search in clockwise direction. If not successful, a DC brake is carried out.
Both Directions
[2]: The flying start will first make a search in the direction determined by the last
reference (direction). If not finding the speed it will make a search in the other direction. If not
successful, a DC brake will be activated in the time set in par.2-02

Disable
Select [0] if this function is not required
Enable
Select [1] to enable the frequency converter to "catch" and control a spinning motor.
Function:
Set a motor start speed. After the start signal, the output speed leaps to set value. Set the start

Function:
Some motors, e.g. cone rotor motors, need extra current/starting speed to disengage the rotor. To
obtain this boost, set the required current in par.1-76

This parameter can be used for hoist applications (cone rotor).
Function:
The parameter enables "High Starting Torque". This is a function, where the Current Limit and
Torque Limit are ignored during start of the motor. The time, from the start signal is given until the
