STARTUP
This chapter describes settings and startup procedures of EtherCAT communication. For the startup procedures other than
the network settings, refer to the following user's manual.
MR-J5-G-N1/MR-J5W-G-N1 User's Manual (Introduction)
Switching SW3-1 "OFF (down)" and SW3-2 "ON (up)" of the DIP switch (SW3) triggers [AL. 011.2 Disabling
control axis setting error] when using the 1-axis servo amplifier.
8.1
Connection with controller
Use the latest ESI file when setting up a controller. If the ESI file is old, newly added objects may not be
usable. For the ESI files usable with your servo amplifier, contact your local sales office.
Set up the controller by following its manual. The EtherCAT Slave Information (ESI) file, which lists information about
communication settings of devices, is available for the controller setup. Store the ESI file on the controller to use it. The
controller configures settings of connected slave stations according to the contents of ESI files for the connected slave
stations.
Connecting Ethernet cables
• Use a twisted pair cable (double shielded) compliant with Ethernet Category 5e (100BASE-TX) or higher as
an Ethernet cable. The maximum cable length between nodes is 100 m.
• When connecting Ethernet cables to servo amplifiers, be aware that CN1A is the IN port and CN1B is the
OUT port.
Connect the Ethernet cable connected to the controller or the preceding servo amplifier to CN1A (IN port). Connect the
Ethernet cable connected with the succeeding servo amplifier to CN1B (OUT port). Leave CN1B (OUT port) open if not using
it.
When the node address is not used, an incorrect connection destination sets node addresses that do not correspond to the
actual connection order and may cause a malfunction, such as an operation of an unintended axis.
The following figure shows a connection example.
