Turning OFF the Power Supply
Do not turn OFF the power supply or remove the USB memory device while the Controller is ac-
cessing the USB memory device. Data may become corrupted, and the Controller will not operate
correctly if it uses corrupted data.
Always turn OFF the power supply before you attempt any of the following.
a) Mounting or removing the Units
b) Assembling the Units
c) Setting rotary switches
d) Connecting cables or wiring the system
e) Connecting or disconnecting the terminal blocks or connectors
Do not disconnect the cable or turn OFF the power supply to the product when downloading data or
programs from the Support Software. You may be unable to download the correct data, which could
result in malfunctions.
Do not turn OFF the power supply when performing write processes to the built-in flash memory.
Data may be corrupted, which could result in malfunctions.
Operation
Confirm that no adverse effects will occur in the system before you attempt any of the following.
Changing the operating mode of the Controller (including changing operation mode setting when
power is turned ON)
Changing the user program or settings
Changing set values or present values
EtherCAT Communications
Make sure that the communications distance, number of nodes connected, and method of connec-
tion for EtherCA
T are within specifications.
Do not connect EtherCAT communication to EtherNet/IP, a standard in-house LAN, or other net-
works. An overload may cause the network to fail or malfunction.
If the Fail-soft Operation Setting parameter is set to Stop, process data communications will stop
for all the slaves when an EtherCAT communications error is detected in a slave. This means that if
a Servo Drive is connected, the Servo turns OFF for all the axes. At that time, the Servo Drive will
operate according to the Servo Drive specifications. Make sure that the fail-soft operation setting re-
sults in safe operation when a device error occurs.
If noise occurs or an EtherCAT slave is disconnected from the network, any current communications
frames may be lost. If frames are lost, slave I/O data is not communicated, and unintended opera-
tion may occur. The slave outputs will behave according to the slave specifications. For details, refer
to the manual for the slave.
When an EtherCAT slave is disconnected or disabled, communications will stop and control of the
outputs will be lost not only for the disconnected slave, but for all slaves connected after it. Confirm
that the system will not be adversely affected before you disconnect or disable a slave.
You cannot use standard Ethernet hubs or repeater hubs with EtherCAT communications. If you use
one of these, a major fault level error or other error may occur.
