EtherCAT connectors (IN & OUT)
Connect the EtherCAT master to the IN connector of the first slave. Connect
the OUT connector on the first slave to the IN connector on the next slave.
Do not connect the OUT connector on the last slave.
Note
Always turn OFF the power supply to the Machine Control Unit
and slaves before connecting or disconnecting the EtherCAT
Communications Cables.
The cable between two nodes (L1, L2 ... Ln) must be 100 m or
less.
Field Ground Terminal
The GRT1-ECT provides a Field Ground Terminal (FG) between the
EtherCAT connectors. If noise is a significant source of errors, ground the
Field Ground Terminal (recommended wire 20 AWG to 14 AWG or 0.5 to
2.0 mm
2
). Strip the wire between 8 mm and 10 mm of insulation at the ends
of the wires (stranded or solid wire) or use pin terminals with a pin
(conductor) length of 8 mm to 10 mm.
