4.4.2.1 OL2 function
4.4.2.1.1 Output frequency dependent OL2 current limit
The power components are more loaded by current in lower frequency range than
in higher output frequencies.
Therefore the permissible current (short time current limit) is lower than the maxi-
mum current (de29 inverter maximum current).
The inverter normally outputs at least rated current as continuous current at 0Hz
output frequency and rated switching frequency. The maximum current is available
from maximum 10 Hz as standard. Detailed information can be found in the instal-
lation manual for the corresponding power unit housing size.
