1-73 Flying Start
Default value: –
Setup:
All setups
Data type: Uint8
This function is not recommended for hoisting applications. For power levels above 55 kW, flux mode must be used to achieve the
best performance.
To obtain the best flying start performance, the advanced motor data, parameter 1-30 Stator Resistance (Rs) to parameter 1-35
Main Reactance (Xh), must be correct.
This function makes it possible to catch a freely spinning motor, for example coasted because of mains dropout. When parameter 1-73
Flying Start is enabled, parameter 1-71 Start Delay has no function. Search direction for flying start is linked to the setting in parameter
4-10 Motor Speed Direction. [0] Clockwise: Flying start searches in clockwise direction. If not successful, a DC brake is carried out. [2] Both
Directions: The flying start first searches in the direction determined by the last reference (direction). If the speed is not found, flying start
searches in the other direction. If not successful, a DC brake activates in the time set in parameter 2-02 DC Braking Time. Start then takes
place from 0 Hz.
