1-03 Torque Characteristics
Default value: [1] Variable Torque
Parameter type: Option
2-setup: All setups
Conversion index: -
Data type: u_int8
Change during operation: False
Select the torque characteristic. VT and AEO are both energy saving operations.
Table 38: Option:
[1] Variable
Torque
For speed control of centrifugal pumps and fans. Also to be used when controlling more than 1 motor from
the same drive (for example, multiple condenser fans or cooling tower fans). Provides a voltage that is opti-
mized for a squared torque load characteristic of the motor.
[3] Auto Ener-
gy Optim.
For optimum energy efficient speed control of centrifugal pumps and fans, it provides a voltage that is opti-
mized for a squared torque load characteristic of the motor. In addition, the AEO feature adapts the voltage
exactly to the current load situation, thereby reducing energy consumption and audible noise from the mo-
tor.
1-06 Clockwise Direction
Default value: [0] Normal
Parameter type: Option
2-setup: 1 setup
Conversion index: -
Data type: u_int8
Change during operation: False
This parameter defines the term
Clockwise
corresponding to the LCP direction arrow. Used for easy change of direction of shaft
rotation without swapping motor wires.
Table 39: Option:
[0] Normal
The motor shaft turns in clockwise direction when drive is connected U
⇒
U; V
⇒
V; and W
⇒
W to motor.
[1] Inverse
The motor shaft turns in counterclockwise direction when drive is connected U
⇒
U; V
⇒
V; and W
⇒
W to motor.
1-08 Motor Control Bandwidth
Default value: [1] Medium
Parameter type: Option
2-setup: All setups
Conversion index: -
Data type: u_int8
Change during operation: False
Table 40: Option:
[0]
High
Suitable for highly dynamic response.
[1]
Medium
Suitable for smooth steady-state operation.
