Trane TR200 - 1-03 Torque Characteristics; 1-29 Automatic Motor Adaptation (AMA)

This parameter cannot be changed when motor is running.
When set for Closed Loop, the commands Reversing and Start Reversing will not reverse the direction of the motor.
1-03 Torque Characteristics
Option: Function:
[0] * Compressor torque
Compressor [0]: For speed control of screw and scroll compressors. Pro-
vides a voltage which is optimized for a constant torque load character-
istic of the motor in the entire range down to 10 Hz.
[1] Variable torque
Variable Torque [1]: For speed control of centrifugal pumps and fans.
Also to be used when controlling more than one motor from the same
frequency converter (e.g. multiple condenser fans or cooling tower fans).
Provides a voltage which is optimized for a squared torque load charac-
teristic of the motor.
[2] Auto Energy Optim. CT
Auto Energy Optimization Compressor [2]: For optimum energy efficient
speed control of screw and scroll compressors. Provides a voltage which
is optimized for a constant torque load characteristic of the motor in the
entire range down to 15Hz 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 per-
formance, the motor power factor cos phi must be set correctly. This
value is set in par. 14-43
Motor Cosphi. The parameter has a default value
which is automatically adjusted when the motor data is programd. 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 (AMA). It is very rarely nec-
essary to adjust the motor power factor parameter manually.
[3] * Auto Energy Optim. VT
Auto Energy Optimization VT [3]: For optimum energy efficient speed
control of centrifugal pumps and fans. Provides a voltage which is opti-
mized for a squared torque load characteristic of the motor but in addi-
tion 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
Motor Cosphi.
The parameter has a default value and is automatically adjusted when
the motor data is programd. These settings will typically ensure opti-
mum 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 (AMA). It is very rarely necessary to adjust the motor power
factor parameter manually.
1-29 Automatic Motor Adaptation (AMA)
Option: Function:
The AMA function optimizes dynamic motor performance by automati-
cally optimizing the advanced motor parameters par. 1-30
Stator Resist-
ance (Rs) to par. 1-35 Main Reactance (Xh)) while the motor is stationary.
