Page 20 Precautions for Safe Use • Do not write on the CPU Unit with ink within the restricted region that is shown in the following figure. Also do not get this area dirty. When the Unit is installed or removed, ink or dirt may adhere to the pins in the NX connector, which may result in malfunctions.
Page 21 Precautions for Safe Use • Do not incline or twist the flat-blade screwdriver while it is in a release hole on a screwless clamping terminal block of CPU Unit. Doing so may damage the terminal block. Terminal Terminal block block •...
Page 22 Precautions for Safe Use Actual Operation • If you change the fail-soft operation setting, the output status when the error occurs may also change. Confirm safety before you change the setting. • If you use fail-soft operation, write programming to determine whether Unit I/O data is valid. Without such programming, the user program cannot distinguish between Units for which I/O refreshing is continued and Units for which I/O refreshing is stopped.
Page 23 Precautions for Safe Use • Always confirm safety at the connected equipment before you reset Controller errors with an event level of partial fault or higher for the EtherCAT Master Function Module. When the error is reset, all slaves that were in any state other than Operational state due to a Con- troller error with an event level of partial fault or higher (in which outputs are disabled) will go to Oper- ational state and the outputs will be enabled.
Page 24 Precautions for Safe Use • All related EtherNet/IP nodes are reset when you transfer settings for the built-in EtherNet/IP port (including IP addresses and tag data links settings). The settings can only be enabled after the reset. Confirm that the system will not be adversely affected by resetting nodes before you transfer the set- tings.
Page 25 Precautions for Safe Use Motion Control • Confirm the axis number carefully before you perform an MC Test Run. • The motor is stopped if communications are interrupted between the Sysmac Studio and the CPU Unit during an MC Test Run. Connect the communications cable between the computer and CPU Unit securely and confirm that the system will not be adversely affected before you perform an MC Test Run.
Page 26 Precautions for Safe Use Restoring Data • You cannot back up, restore, or compare some or all of the settings for certain slaves and Units. Also, you cannot back up, restore, or compare data for disabled slaves or Units. After you restore data, suf- ficiently confirm that operation is correct before you start actual operation.
Page 27 Precautions for Safe Use Disposal • Dispose of the Units and Batteries according to local ordinances as they apply. • The following information must be displayed for all products that contain primary lithium batteries with a perchlorate content of 6 ppb or higher when shipped to or transported through the State of California, USA. Perchlorate Material - special handling may apply.
Page 28: Precautions For Correct Use
Precautions for Correct Use Precautions for Correct Use Storage and Installation • Follow the instructions in this manual to correctly perform installation. • Do not operate or store the Controller in the following locations. Doing so may result in burning, in operation stopping, or in malfunction.
Page 29 Precautions for Correct Use • For EtherCAT and EtherNet/IP, use the connection methods and cables that are specified in the NJ/NX-series CPU Unit Built-in EtherCAT Port User’s Manual (Cat. No. W505) and the NJ/NX-series CPU Unit Built-in EtherNet/IP Port User’s Manual (Cat. No. W506). Otherwise, communications may be faulty.
Page 30 If there is a corrupted file in the SD Memory Card, the file is automatically deleted by the restoration function when the power supply is turned ON. • If you use an OMRON SD Memory Card, the end of the life of the SD Memory Card can be detected in the following ways.
Page 31 Precautions for Correct Use Online Editing • When performing online editing, the CPU Unit saves a program updated by the online editing to built-in non-volatile memory.
