Power and current:

Nom. input current of the converter InIN :effective input current of the converter ( depends from cos Φ of a motor and other)
Nom. output current of the converter:nominal and maximum permanent output current of the converter
Motor power: recommended maximum power of a motor connectable to converter's output (holds for 4 - pole motors)

In - nominal output current of the converter for variable load
In60 - maximal output current of the converter that is equalled 1,5 x InL for the duration of 60 s each 10 min (this relates only to constant load)
In2 - maximal output current of the converter that is equalled 2 x InL for the duration of 2 each 15 s (this relates only to constant load)
