VLT® Flow Drive FC 111
Programming Guide
Set a time constant for the current limit controller low-pass filter. A shorter period makes the control react faster to changes in cur-
rent.

4.11.5 14-4* Energy Optimization
Parameters for adjusting the energy optimization level in both variable torque (VT) and automatic energy optimization (AEO) mode.
Automatic energy optimization is only active if parameter 1-03 Torque Characteristics is set to [3] Auto Energy Optim.
14-40 VT Level
Default value: 90%
Conversion index: 0
Enter the level of motor magnetization at low speed. Low values reduce energy loss in the motor, but also reduce load capability.
Table 252: Range:
Min: 40%
14-41 AEO Minimum Magnetisation
Default value: 66%
Conversion index: 0
Enter the minimum allowable magnetization for AEO. Low values reduce energy loss in the motor, but also reduce resistance to
sudden load changes.

Min: 40%
14-44 d-axis current optimization for IPM
Default value: 100%
Conversion index: 0
This parameter is available only when parameter 1-10 Motor Construction is set to [2] PM, salient IPM, non-Sat. Normally, VVC
control automatically optimizes d-axis demagnetizing current based on d-axis and q-axis settings. When parameter 1-10 Motor Con-
struction is set to [2] PM, salient IPM, non-Sat, use this parameter to compensate the saturation effect at high load. Usually, decreas-
ing this value improves the efficiency. However, 0% means no optimization and the d-axis current is 0 (this is not recommended).

4.11.6 14-5* Environment
These parameters help the drive to operate under special environmental conditions.
14-50 RFI Filter
Default value: [1] On
Conversion index: -
This parameter is only valid for drives of the following enclosure sizes:
• IP20, 3x380–480 V, enclosure sizes H6–H8.
