Serial ports 
COM1 
RS485  available  on  terminal  block 
(A,B,C)  and  on  COM  plug-8  poles 
(galvanically isolated). 
EXP1 
RS232 available on terminal  block  (non 
isolated). CAN bus for I/O expansion.

 First encoder input uses hardware inputs I1 and I2. Second encoder input 
uses hardware inputs I3  and I4.  If encoder inputs  are used, the relevant 
digital inputs are not available. Max. frequency for encoders is 25 KHz if not 
used contemporarily, 15 KHz if both inputs are used contemporarily.
