1-71 Start Delay
Range:
0.0 s* [0.0 - 120.0 s]
1-73 Flying Start
Option:
[0] * Disabled
[1] Enabled
When par. 1-73 is enabled, par. 1-71
Search direction for flying start is linked to the setting in par. 4-10, Motor Speed Direction.
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, Braking Time. Start will then take place
from 0 Hz.
1-74 Start Speed [RPM]
Range:
0 RPM* [0 - 600 RPM]
1-75 Start Speed [Hz]
Range:
0 Hz* [0.0 - 500.0 Hz]
1-76 Start Current
Range:
0.00 A* [0.00 - par. 1-24 A]
2.3.8 1-8* Stop Adjustments
Parameters for setting special stop features for the motor.
1-80 Function at Stop
Option:
[0] * Coast
[1] DC Hold/Motor Preheat
Function:
The function selected in par.1-80
Enter the time delay required before commencing acceleration.
Function:
This function makes it possible to catch a motor, in both directions, which is spinning freely due to
a mains drop-out.
No function
Enables frequency converter to "catch" and control a spinning motor.
Start Delay has no function.
Function:
Set a motor start speed. After the start signal, the output speed leaps to set value. Set the start
function in par. 1-72 Start Function
Delay .
Function:
Set a motor start speed. After the start signal, the output speed leaps to set value. Set the start

function in par. 1-72
Delay .
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
[RPM] . Set par. 1-72
Delay .
This parameter can be used for hoist applications (cone rotor).
Function:
Select the frequency converter function after a stop command or after the speed is ramped down
to the settings in par.1-81
Leaves motor in free mode.
