ACH580 E-Clipse bypass and packaged drive user manual 77
Embedded fieldbus
• Do not directly ground the EIA 485 network at any point. Ground all devices on
the network using their corresponding earthing terminals.
• As always, the grounding wires should not form any closed loops, and all the
devices should be earthed to a common ground.
• Connect the EIA 485 link in a daisy-chained bus, without dropout lines.
• Do not connect the shield at the bypass. Tie the shields together at the bypass.
Only load the shield connection at the EIA 485 master.
• For configuration information see the following:
– Communication setup – EFB section.
– Activate drive control functions – EFB section.
– The appropriate EFB protocol specific technical data.
– To reduce noise on the network, terminate the EIA 485 network using 120
Ω
resistors at both ends of the network. Use the DIP switch to connect or
disconnect the termination resistors. Refer to page 78 for the diagram and
table.
