2 Starting a Sample System
2 - 16 EtherCAT Communication Unit USER’S MANUAL (3G3AX-MX2-ECT)
Securely connect the EtherCAT communication cable connector to the EtherCAT Communication Unit
by inserting the connector all the way until it clicks.
Connect the communication cable from the EtherCAT master side to the communication connector IN
of the Communication Unit.
Connect the communication connector OUT to the communication connector IN of the next EtherCAT
slave.
Do not connect the communication connector OUT of the last EtherCAT slave.
Data will not be communicated correctly if the input/output are connected in reverse.
In the system configuration example used in this chapter, the connectors below are connected with the
communications cables.
(Notes) Do not connect anything to 2nd inverter OUT.
If a slave other than this product is used in your system configuration, set the unit in the same way by
referring to its User Manual.
• When constructing an EtherCAT network, take sufficient safety measures according to the standards.
We recommend that specialized constructors familiar with the safety measures and standards be
requested to perform the construction.
• Do not install EtherCAT network devices near devices generating noise.
If there is no choice but to install them down in an environment with a high level of noise, be sure to
take measures against the noise, such as covering each device in metal cases.
• To connect a cable to the communications connector of a device, insert it securely until the connector
of the communications cable is locked.
• Install and wire the communications cables separately from high-voltage electrical power lines.
• Do not install the cables near devices generating noise.
• Do not install the cables in high-temperature and high-humidity environments.
• Use the cables in locations without powder dust or oil mist.
