Function:
10Hz
*
[5 - 40 Hz]
Enter the minimum frequency at which the Automatic Energy Optimisation (AEO) is to be active.
14-43 Motor Cosphi
Range:
Function:
0.66
*
[0.40 - 0.95]
The Cos(phi) setpoint is automatically set for optimum AEO performance during AMA. This parameter should
normally not be altered. However in some situations it may be necessary to enter a new value to fine-tune.
3.14.7. Environment, 14-5*
These parameters help the frequency converter to operate under special environmental conditions.

[0] only if the frequency converter is fed by an isolated mains source, i.e. from a special IT mains
source.
In this mode, the internal RFI filter capacitors between chassis and the mains RFI filter circuit are cut-out to
avoid damage of the intermediate circuit and to reduce the ground capacity currents according to IEC 61800-3.
