c) Turn the power OFF and ON of the third-party slave, and check that other slaves are not in any
errors.
EtherNet/IP Communications
• Unexpected operation may result if inappropriate data link tables are set. Even if appropriate data
link tables have been set, confirm that the controlled system will not be adversely affected before
you transfer the data link tables. The data links start automatically after the data link tables are
transferred.
• If EtherNet/IP tag data links (cyclic communications) are used with a repeating hub, the communica-
tions load on the network will increase. This will increase collisions and may prevent stable commu-
nications. Do not use repeating hubs on networks where tag data links are used. Use an Ethernet
switch instead.
• Make sure to use the communications distance, number of nodes connected, and method of con-
nection for EtherNet/IP within specifications. Do not connect EtherNet/IP communications to Ether-
CAT or other networks. An overload may cause the network to fail or malfunction.
Motion Control
• The motor is stopped if communications are interrupted between the Power PMAC IDE and the
Controller during a Test Run. Connect the communications cable securely and confirm that the sys-
tem will not be adversely affected before you perform a Test Run.
• EtherCAT communications are not always established immediately after the power supply is turned
ON. Use the system-defined variables in the user program to confirm that communications are es-
tablished before attempting control operations.
• When you create a servo algorithm, take fail-safe measures in the user program which includes the
servo algorithm.
Unit Replacement
• Make sure that the required data, including the user program, configurations, settings, and varia-
bles, is transferred to the Controller that was replaced and to externally connected devices before
restarting operation.
Upgrading the Power PMAC IDE
• After you upgrade a project file created with an older version of the Power PMAC IDE for use with a
newer version of Power PMAC IDE, perform a test run before use to check that the project file was
upgraded correctly.
Maintenance
• Do not attempt to disassemble, repair, or modify the Controller. Doing so may result in a malfunction
or fire.
