VLT® Flow Drive FC 111
Programming Guide
Table 37: Option:
[0] U/f
When running U/f, control slip and load compensations are not included.
Used for parallel-connected motors and/or special motor applications. Set the U/f settings in parameter 1-55 U/f
Characteristic - U and parameter 1-56 U/f Characteristic - F.

[1] VVC
When parameter 1-10 Motor Construction is set to PM-enabled options, only VVC
Normal running mode, including slip and load compensations.
1-03 Torque Characteristics
Default value: [1] Variable Torque
Conversion index: -
Select the torque characteristic. VT and AEO are both energy saving operations.
Table 38: Option:
[1] Variable For speed control of centrifugal pumps and fans. Also to be used when controlling more than 1 motor from
Torque 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- For optimum energy efficient speed control of centrifugal pumps and fans, it provides a voltage that is opti-
gy Optim. 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
Conversion index: -
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
Conversion index: -
Table 40: Option:
[0] High Suitable for highly dynamic response.
[1] Medium Suitable for smooth steady-state operation.
