, the
stator leakage reactance X

and the main
reactance X
h
.
[2] Enable reduced AMA Performs a reduced AMA of the stator resistance R
s
in the system only.
Select this option if an LC filter is used between the frequency converter
and the motor.
Activate the AMA function by pressing [Hand on] after selecting [1] or [2]. See also the item
Automatic Motor
Adaptation
in the Design Guide. After a normal sequence, the display will read: “Press [OK] to finish AMA”.
After pressing the [OK] key the frequency converter is ready for operation.
• For the best adaptation of the frequency converter, run AMA on a cold motor
• AMA cannot be performed while the motor is running
Avoid generating external torque during AMA.
If one of the settings in par. 1-2* Motor Data is changed, par. 1-30
Stator Resistance (Rs) to par. 1-39 Motor Poles, the
advanced motor parameters, will return to default setting.
This parameter cannot be adjusted while the motor is running.
Full AMA should be run without filter only while reduced AMA should be run with filter.
See section:
Application Examples > Automatic Motor Adaptation
in the Design Guide.
1-71 Start Delay
Range: Function:
0.0 s* [0.0 - 120.0 s] The function selected in par. 1-80
Function at Stop is active in the delay
period.
Enter the time delay required before commencing acceleration.
1-73 Flying Start
Option: Function:
This function makes it possible to catch a motor which is spinning freely
due to a mains drop-out.
When par. 1-73
Flying Start is enabled, par. 1-71 Start Delay has no func-
tion.
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
DC Braking Time. Start will
then take place from 0 Hz.
