(-RS2) with additional optional/integrated RS232 interface on SK 700E frequency inverters ≤ 22.0 kW.
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.
Table 4: Overview SK 5xxE standard and incremental encoder input
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.
