Page 12: Safety Precautions
Safety Precautions Safety Precautions Definition of Precautionary Information The following notation is used in this manual to provide precautions required to ensure safe usage of an NX-series Controller. The safety precautions that are provided are extremely important to safety. Always read and heed the information provided in all safety precautions. The following notation is used.
Page 13: Warnings
Safety Precautions Warnings WARNING During Power Supply Do not touch any of the terminals or terminal blocks while the power is being supplied. Doing so may result in electric shock. Do not attempt to take any Unit apart. In particular, high-voltage parts are present in the Power Supply Unit while power is supplied or immediately after power is turned OFF.
Page 14 Safety Precautions Unintended outputs may be performed when an error occurs in variable memory or memory for CJ-series Units. As a countermeasure for such prob- lems, external safety measures must be provided to ensure safe operation of the system. Provide measures in the communications system and user program to ensure safety in the overall system even if errors or malfunctions occur in data link communications or remote I/O communications.
Page 15: Cautions
Safety Precautions Cautions Caution Application Do not touch any Unit when power is being supplied or immediately after the power supply is turned OFF. Doing so may result in burn injury. Wiring Be sure that all terminal screws and cable connector screws are tightened to the torque specified in the relevant manuals.
Page 16: Precautions For Safe Use
Precautions for Safe Use Precautions for Safe Use Disassembly and Dropping • Do not attempt to disassemble, repair, or modify any Units. Doing so may result in malfunction or fire. • Do not drop any Unit or subject it to abnormal vibration or shock. Doing so may result in Unit malfunc- tion or burning.
Page 17 Precautions for Safe Use Installation • Always connect to a ground of 100 Ω or less when installing the Units. Wiring • Follow the instructions in this manual to correctly perform wiring. Double-check all wiring and switch settings before turning ON the power supply. •...
Page 18 Precautions for Safe Use Turning ON the Power Supply • It takes up to approximately 10 to 20 s to enter RUN mode after the power is turned ON. The outputs during this time behave according to the slave or Unit specifications. Use the RUN output on the Power Supply Unit, for example, to implement fail-safe circuits so that external devices do not oper- ate incorrectly.
Page 19 Precautions for Safe Use Operation • Confirm that no adverse effect will occur in the system before you attempt any of the following. a) Changing the operating mode of the CPU Unit (including changing the setting of the Startup Mode) b) Changing the user program or settings c) Changing set values or present values d) Forced refreshing...
Page 20 Precautions for Safe Use Debugging • Forced refreshing ignores the results of user program execution and refreshes I/O with the specified values. If forced refreshing is used for inputs for which I/O refreshing is not supported, the inputs will first take the specified values, but they will then be overwritten by the user program. This operation differs from the force-set/reset functionality of the CJ-series PLCs.
Page 21 Precautions for Safe Use EtherCAT Communications • Make sure that the communications distance, number of nodes 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 net- works.
Page 22 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 23 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 24 Precautions for Safe Use Unit Replacement • Make sure that the required data, including the user program, configurations, settings, variables, and memory used for CJ-series Units, is transferred to a CPU Unit that was replaced and to externally connected devices before restarting operation. Be sure to include the tag data link settings and routing tables, which are stored in the CPU Unit.
Page 25: 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. Operation may stop or malfunctions may occur. a) Locations subject to direct sunlight b) Locations subject to temperatures or humidity outside the range specified in the specifications c) Locations subject to condensation as the result of severe changes in temperature...
Page 26 Precautions for Correct Use Wiring • Do not allow foreign matter to enter the openings in the Unit. Doing so may result in Unit burning, electric shock, or failure. • Do not allow wire clippings, shavings, or other foreign material to enter any Unit. Otherwise, Unit burning, failure, or malfunction may occur.
Page 27 Precautions for Correct Use Transferring Programs • If you use the program transfer from SD Memory Card, set to enter the password for each execution to prevent an unexpected program transfer. Replacing Slaves and Units • If you replace a slave or Unit, refer to the operation manual for the slave or Unit for information on the data required for individual slaves or Units and redo the necessary settings.
Page 28 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: Versions
Versions Versions Hardware revisions and unit versions are used to manage the hardware and software in NX-series Units and EtherCAT slaves. The hardware revision or unit version is updated each time there is a change in hardware or software specifications. Even when two Units or EtherCAT slaves have the same model number, they will have functional or performance differences if they have different hardware revisions or unit versions.
