NOTICE Encoder supply voltage
Rotary encoder with 5 V power supply must not be connected to the SK 5xxE frequency inverters directly. For
this application, a commercially external power supply should be used because the SK 5xxE frequency inverters
only feature a 10…30 V output for connection of a incremental encoder.
This is why the rotary encoders must be replaced or the "old" encoders must be supplied from an external 5 V
power supply when migrating to SK 5xxE frequency inverters.
