    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 15: 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 16 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 17: 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 18: 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 19 Precautions for Safe Use Installation • Always connect to a ground of 100 Ω or less when installing the Units. • If the LG and GR terminals are connected, make sure to connect them firmly. The LG terminal that is a noise-filtered neutral terminal, has a half electrical potential of the input voltage.
  • Page 20 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 21 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 22 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 23 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 24 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 25 Precautions for Safe Use Data Backup • We recommend that you back up the present values of variables while the retained variables are not refreshed. If you back up while the values of retained variables are refreshed, the data may not be saved cor- rectly.
  • Page 26 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 27: 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 28 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 29 Precautions for Correct Use Debugging • If you use data tracing to sample following variables, correct data may not be sampled. a) Structure members whose data size is 16 bits or more, except for system-defined variables for motion control b) Array elements whose data size is 16 bits or more For information on data tracing, refer to the NJ/NX-series CPU Unit Software User’s Manual (Cat.
