No. Step
1
Check whether the communication network cables meet the
specification requirements of shielded Cat 5e cables.
2
Check whether the communication port is loose or in poor
contact.
3
Separate the communication cable and power cable at a
distance of at least 30 cm.
4
For multi‑node communication, add an equipotential bonding
wire between the nodes.
5
The maximum cable length allowed between two nodes is 100
m.
6
Add a magnetic buckle at both ends of the communication cable
and wind the communication cable for one to two turns.
7
Wind the output U/V/W cables of the AC drive on a magnetic ring
for two to four turns.
8
Use a shielded power cable and ground the shielding layer
securely.
9
Installation the EtherCAT communication expansion card to
optional expansion card slot 2.
