Precautions for Correct Use
Restoring Data
• When you edit the restore command file, do not change anything in the file except for the "yes" and
"no" specifications for the selectable data groups. If you change anything else in the file, the Control-
ler may perform unexpected operation when you restore the data.
Task Settings
• If a Task Period Exceeded error occurs, shorten the programs to fit in the task period or increase the
setting of the task period.
Motion Control
• Before you start an MC Test Run, make sure that the operation parameters are set correctly.
• Do not download motion control settings during an MC Test Run.
EtherCAT Communications
• Set the Servo Drives to stop operation if an error occurs in EtherCAT communications between the
Controller and a Servo Drive.
• If you need to disconnect the cable from an EtherCAT slave during operation, first disconnect the
software connection to the EtherCAT slave or disable the EtherCAT slave and all of the EtherCAT
slaves that are connected after it.
• Make sure that all of the slaves to be restored are participating in the network before you reset a
Network Configuration Verification Error, Process Data Communications Error, or Link OFF Error in
the EtherCAT Master Function Module. If any slave is not participating when any of these errors is
reset, the EtherCAT Master Function Module may access slave with a different node address than
the specified node address or the error may not be reset correctly.
• Make sure that the communications distance, number of devices connected, and method of connec-
tion for EtherCAT are within specifications. Do not connect EtherCAT communications to
EtherNet/IP, a standard in-house LAN, or other networks. An overload may cause the network to fail
or malfunction.
• After you transfer the user program, the product is restarted and communications with the EtherCAT
slaves are cut off. During that period, the slave outputs behave according to the slave specifications.
The time that communications are cut off depends on the EtherCAT network configuration. Before
you transfer the user program, confirm that the system will not be adversely affected.
Battery Replacement
• Turn ON the power after replacing the battery for a product that has been unused for an extended
period of time. Leaving the product unused without turning ON the power even once after the battery
is replaced may result in a shorter battery life.
• Make sure to use a battery of the correct type, install the battery properly.
• Apply power for at least five minutes before changing the battery. Mount a new battery within five
minutes after turning OFF the power supply. If power is not supplied for at least five minutes, the
clock data may be lost. Check the clock data after changing the battery.
