3.3 Main Menu - Load and Motor - Group 1
3.3.1 General Settings, 1-0*
Define whether the frequency converter operates in open loop or closed loop.
1-00 Configuration Mode
Option: Function:
[0] * Speed Open Loop
[3] Process Closed Loop
NB!
This parameter cannot be changed when motor is running.
NB!
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 CT For 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 15 Hz.
[1] Condenser VT 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 characteristic of the motor.
[2] Compressor AEO CT
Auto Energy Optimization Compressor
. 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 performance, the motor power factor cos phi must be set correctly.
This value is set in par. 14-43, Motor cos phi. The parameter has a default value which is automat-
ically adjusted when the motor data is programmed. 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 necessary to adjust the
motor power factor parameter manually.
[3] Single fan/ pump AEO Auto Energy Optimization VT . For optimum energy efficient speed control 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, Motor cos phi.
The parameter has a default value and is automatically adjusted when the motor data is program-
med. 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 necessary to adjust the motor power factor parameter manually.
3.3.2 1-2* Motor Data
Parameter group 1-2* comprises input data from the nameplate on the connected motor.
Parameters in parameter group 1-2* cannot be adjusted while the motor is running.
