NOTES:
•
Monitored Fieldbus: for information, see
.
•
Keep comunication cables far from supply and feedback cables.
•
It may be necessary to use a repeter or signal amplifier for bus lenght grater than 1000m.
•
Use shielded patch cable (pin-to-pin) FTP 568 (B) Cat. 5 or better.
•
As to connect multiple drives, RJ45 needs a cascade connection, so the wiring between the drives
themselves must be pin-to-pin.
•
Node id address is settable via keybord; please see
“6.06 Display and keyboard” pag. 76
