References
IOEC modules
—
• Connect the cables for digital and analog input
6-13 Shield grounding
point for encoder cable
and output signals to the IOEC modules.
Conductors
• If a twisted pair cable is used, leave the
unshielded cable ends twisted until they reach
the terminals.
• Leave unshielded conductor ends as short as
possible (not longer than 50 mm).
Cable shields
1. Connect the shield of serial communications
cables to the fieldbus adapter.
2. Connect the overall shield and the individual
shields of the encoder cable to the separate
shield grounding bracket (3). Do not connect
the shields directly to the encoder adapter (1).
To accommodate encoder cables of different
diameters, ground clamps
are supplied.
