2.2.4 Endat encoders
(SK 540E and above)
Endat encoders function in a similar manner to SSI encoders with 2 RS485 channels, whereby the data
channel is bi-directional. The communication frequency of the inverter is 200kHz.
Endat encoders are also available with an integrated incremental track. The settings for the incremental
track correspond to those of a conventional incremental encoder.
The supply voltage for the encoder is 3.6-14V. An external source (recommended: >5V) or the internal 12V
can be used as the voltage supply.
