The token X represents A (with integrated mains filter) on SK 700E frequency inverters ≤ 22.0 kW
O (without integrated mains filter) on SK 700E frequency inverters ≥ 30.0 kW
** The cable lengths must be taken into account because the mains filter characteristics can vary.

When using a great number of digital control signals (number of used (from SK 700E + option) and available (SK
5xxE) digital inputs. The IO extension SK EBIOE-2 (275900210) can only be connected to SK 540E and SK 545E
frequency inverters.

NOTICE Encoder supply voltage
Incremental encoders with 5 V supply voltage can be directly operated with frequency inverters of the SK 700E
series. For the SK 5xxE series of frequency inverters, the connected incremental encoders must be suitable for a
supply voltage range of 10
V … 30 V.
This is why the incremental encoders must be replaced or the "old" encoders must be supplied from an external
power supply when migrating to SK 5xxE frequency inverters.
