2.2.3  Assignment of CAN interface in SK 530E 

 
The 24V supply for the absolute encoder and for the CAN-Bus/CANopen interfaces must be implemented via an 
external voltage supply. For the terminal assignment please refer to the operating instructions of the encoder 
manufacturer. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

 
 

RECOMMENDATION:  

We recommend the use of an RJ-45 transfer module for the connection of the 24V  
voltage supply.
