Danfoss VLT AQUA Drive FC 202 Programming Guide

NOTICE
•
For the best adaptation of the frequency
converter, run AMA on a cold motor.
•
AMA cannot be performed while the motor is
running.
NOTICE
Avoid generating external torque during AMA.
NOTICE
If 1 of the settings in parameter group 1-2* Motor Data is
changed, parameter 1-30 Stator Resistance (Rs) to
parameter 1-39 Motor Poles return to the default setting.
This parameter cannot be adjusted while the motor is
running.
NOTICE
Full AMA should be run without lter only, while reduced
AMA should be run with lter.
See the chapter Automatic Motor Adaptation in the VLT
®
AQUA Drive FC 202 Design Guide.
3.3.8 1-3* Adv. Motor Data
Parameters for advanced motor data. The motor data in
parameter 1-30 Stator Resistance (Rs) to
parameter 1-39 Motor Poles must match the relevant motor
to run the motor optimally. The default settings are gures
based on common motor parameter values from normal
standard motors. If the motor parameters are not set
correctly, a malfunction of the frequency converter system
may occur. If the advanced motor data is not known,
running an AMA is recommended. See the chapter
Automatic Motor Adaptation in the VLT

AQUA Drive FC 202
Design Guide. The AMA sequence adjusts all motor
parameters except the inertia moment of the rotor and the
iron loss resistance (parameter 1-36 Iron Loss Resistance
(Rfe)).
