  • Page 16 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.

  • Page 17: Cautions

    Safety Precautions 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 18: Precautions For Safe Use

    Safety Precautions The NX-series Controller continues normal operation for a certain period of time when a momentary power interruption occurs. This means that the NX-series Controller may receive incorrect signals from external devices that are also affected by the power in- terruption.
  • Page 19 Safety Precautions Be sure that all terminal screws and cable connector screws are tightened to the tor- que specified in the relevant manuals. The loose screws may result in fire or malfunc- tion. When you connect a computer or other peripheral device to a Controller that has a non-isolated DC Power Supply Unit, either ground the 0-V side of the external power supply or do not ground it at all.
  • Page 20 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 mal- function or burning.
  • Page 21 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. Therefore, if you touch the metallic part of the LG terminal, GR terminal, or Controller, while the GR terminal is not grounded, it may result in electrical shock even when a normal operation is performed.
  • Page 22 Precautions for Safe Use • Apply the voltage between the Power Supply Unit’s L1 or L2 terminal and the GR terminal when testing insulation and dielectric strength. • Do not supply AC power from an inverter or other device with a square-wave output. Internal tem- perature rise may result in smoking or burning.
  • Page 23 Precautions for Safe Use Task Design • If the following variables are specified for a condition expression when the execution condition is a condition expression for a variable, event tasks may not be executed when conditions are met or event tasks may be executed when conditions are not met. 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...
  • Page 24 Precautions for Safe Use If that error is detected, variables with a Retain attribute are set to their initial values and the Hold- ing, DM, and EM Areas in memory used for CJ-series Units are cleared to all zeros. Perform thorough verifications and provide sufficient measures to ensure that the devices perform safe operation for the initial values of the variables with Retain attributes and the resulting operation.
  • Page 25 Precautions for Safe Use communications. Do not use repeating hubs on networks where tag data links are used. Use an Ethernet switch instead. • When you use two EtherNet/IP networks separately, provide separate hubs to connect nodes in each network. •...
  • Page 26 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 27: Precautions For Correct Use

    Precautions for Safe Use • If you change the unit conversion settings, perform homing again. If you do not perform homing, un- intended operation of the controlled system may occur. Data Backup • We recommend that you back up the present values of variables while the retained variables are not refreshed.
  • Page 28 Precautions for Safe Use After you replace the Battery, connect the Sysmac Studio and clear the Low Battery Voltage error. Fan Unit Replacement • Do not touch the heatsink inside the CPU Unit immediately after turning OFF the power supply. Doing so may result in burn injury.
  • Page 29 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 30 Precautions for Correct Use • Do not allow wire clippings, shavings, or other foreign material to enter any Unit. Otherwise, Unit burning, failure, or malfunction may occur. Cover the Units or take other suitable countermeasures, especially during wiring work. • 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.

  • Page 31: Regulations And Standards

    Precautions for Correct Use Restoring and Automatically Transferring Data • When you edit the restore command file or the automatic transfer command file, do not change any- thing in the file except for the “yes” and “no” specifications for the selectable data groups. If you change anything else in the file, the Controller may perform unexpected operation when you restore or automatically transfer the data.

  • Page 32: Conformance To Ul And Csa Standards

    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 33: Versions

    It is recommended that you erase the data on your responsibility before disposing of or transferring the device. Omron shall not be liable for any loss, damage, or other expenses incurred directly or indirectly in the event of any information leakage due to disposal or transfer.
  • Page 34 Concepts  EMC Directives OMRON devices that comply with EU Directives also conform to the related EMC standards so that they can be more easily built into other devices or the overall machine. The actual products have been checked for conformity to EMC standards.* Whether the products conform to the standards in the system used by the customer, however, must be checked by the customer.

  • Page 35: Unit Versions Of Cpu Units And Sysmac Studio Versions

    The NJ/NX-series Controllers comply with the following shipbuilding standards. Applicability to the shipbuilding standards is based on certain usage conditions. It may not be possible to use the product in some locations. Contact your OMRON representative before attempting to use a Controller on a ship.

    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 hard- ware revisions or unit versions.
