Connection Of Ethernet Function - Mitsubishi Electric MELDAS 60 Series Maintenance Manual

12.4 Connection of Ethernet Function

The HR534 card is used to use Ethernet communication. Either the 10BASE-T or 10BASE-5 Ethernet
can be selected for HR534. When using 10BASE-5, set the changeover switch SW1 shown below up,
and when using the 10BASE-T, set SW1 down. The BASE-5 and BASE-T connectors cannot be used
simultaneously.
As there are many environment types and varieties in which the Ethernet communication is used, install
a ferrite on the communication cable's NC side connector end to stabilize the NC operation.

Precautions for use
1) Install the ferrite within 10cm from the end of the NC side connector.
2) Use a shielded cable for the 10BASE-T cable.
3) Do not wire the Ethernet cable in parallel with the drive line. Pass the cable through a dedicated
duct, or separate to at least 10cm away from other wiring.
4) Correctly set the BASE-5/BASE-T changeover switch.
