Function:
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.
Function:
Off
Select [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.
On
Select [1] to ensure that the frequency converter complies with EMC
standards.
Function:
Select the minimum speed of the main fan.
Select Auto [0] to run the fan only when the internal temperature of the
frequency converter is in the range +35°C to approximately +55°C. The
fan will run at low speed at +35°C and at full speed at approximately
+55°C.
Function:
Select which reaction the frequency converter should take in case a fan
fault is detected.
