These settings will typically ensure optimum motor voltage but if the
motor power factor cos phi requires tuning, an AMA function can be
carried out using par.1-29 Automatic Motor Adaptation

Auto Energy Optimization VT
trol of centrifugal pumps and fans. Provides a voltage which is optimized
for a squared torque load characteristic of the motor but in addition the
AEO feature will adapt the voltage exactly to the current load situation,
thereby reducing energy consumption and audible noise from the motor.
To obtain optimal performance, the motor power factor cos phi must be
set correctly. This value is set in par.14-43
has a default value and is automatically adjusted when the motor data is
programmed. These settings will typically ensure optimum motor volt-
age but if the motor power factor cos phi requires tuning, an AMA
function can be carried out using par.1-29
(AMA). It is very rarely necessary to adjust the motor power factor pa-
rameter manually.
