Danfoss VLT HVAC Basic Drive FC 101 Programming Guide

1-29 Automatic Motor Adaption (AMA)
Option: Function:
NOTICE
This parameter cannot be adjusted while
the motor is running.
The AMA function optimizes dynamic motor
performance by automatically optimizing the
advanced motor parameters while the motor is
stationary.

O No function
[1] Enable
Complete
AMA
When parameter 1-10 Motor Construction is set
to [0] Asynchron, perform AMA of
parameter 1-30 Stator Resistance (Rs),
parameter 1-33 Stator Leakage Reactance (X1),
and parameter 1-35 Main Reactance (Xh).
When parameter 1-10 Motor Construction is set
to options that enable permanent motors,
perform AMA of parameter 1-30 Stator
Resistance (Rs), and parameter 1-37 d-axis
Inductance (Ld).
NOTICE
Terminal 27 Digital Input
(parameter 5-12 Terminal 27 Digital Input)
has coast inverse as the default setting.
This means that AMA cannot be
performed if there is no 24 V to terminal
27.
[2] Enable
Reduced
AMA
Performs a reduced AMA of the stator
resistance R
s
in the system only. Select this
option if an LC lter is used between the
frequency converter and the motor.
NOTICE
When parameter 1-10 Motor Construction is set to options
that enable permanent motor mode, the only option
available is [1] Enable Complete AMA.
Activate the AMA function by pressing [Hand On] after
selecting [1] Enable Complete AMA or [2] Enable Reduced
AMA. After a normal sequence, the display reads: Press [OK]
to nish AMA. After pressing [OK], the frequency converter
is ready for operation.
NOTICE
•
For the best adaptation of the frequency
converter, run AMA on a cold motor.
•
AMA cannot be performed while the motor is
running.
•
AMA cannot be performed on a motor with a
bigger power rating than the frequency
converter, for example, when a 5.5 kW (7.4 hp)
motor is connected to a 4 kW (5.4 hp)
frequency converter.
NOTICE
Avoid generating external torque during AMA.
NOTICE
If one of the settings in parameter group 1-2* Motor Data
is changed, the advanced motor parameters,
parameter 1-30 Stator Resistance (Rs) to
parameter 1-39 Motor Poles, return to default setting.
NOTICE
Perform a full AMA without lter only, while reduced
AMA should be run with a lter.
3.2.5 1-3* Motor Data II
This parameter group comprises input data from the
nameplate on the connected motor.
NOTICE
These parameters cannot be adjusted while the motor is
running.
1-30 Stator Resistance (Rs)
Range: Function:
Size related* [ 0.0 - 9999.000

Set the stator resistance value.
Enter the value from a motor
datasheet or perform an AMA on
a cold motor.
1-33 Stator Leakage Reactance (X1)
