  • Page 19: 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 NJ-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 20 Symbols The circle and slash symbol indicates operations that you must not do. The specific operation is shown in the circle and explained in text. This example indicates prohibiting disassembly. The triangle symbol indicates precautions (including warnings). The specific operation is shown in the triangle and explained in text. This example indicates a precaution for electric shock.
  • Page 21 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 22 WARNING Fail-safe Measures Unintended outputs may occur when an error occurs in variable memory or in memory used 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 23 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 24: 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 25 • Do not apply voltages or connect loads to the Output Units or slaves in excess of the maximum rat- ings. • Surge current occurs when the power supply is turned ON. When selecting fuses or breakers for external circuits, consider the above precaution and allow sufficient margin in shut-off performance. Refer to the relevant manuals for surge current specifications.

  • Page 27 • You cannot upload or download information for forced refreshing with the Sysmac Studio. After downloading data that contains forced refreshing, change to RUN mode and then use the Sys- mac Studio to perform the operation for forced refreshing. Depending on the difference in the forced status, the control system may operate unexpectedly. •...
  • Page 28 • 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 estab- lished before attempting control operations. • If frames sent to EtherCAT slaves are lost due to noise or other causes, slave I/O data is not commu- nicated, and the intended operation is sometimes not achieved.
  • Page 29 Unit Replacement • We recommend replacing the Battery with the power turned OFF to prevent the CPU Unit’s sensitive internal components from being damaged by static electricity and to prevent malfunctions. The Bat- tery can be replaced without turning OFF the power supply. To do so, always touch a grounded piece of metal to discharge static electricity from your body before you start the procedure.

  • Page 30: Precautions For Correct Use

    Precautions for Correct Use Storage, Mounting, and Wiring • Do not operate or store the Controller in the following locations. Operation may stop or malfunctions may occur. • Locations subject to direct sunlight • Locations subject to temperatures or humidity outside the range specified in the specifications •...
  • Page 31 Error Processing • In applications that use the results of instructions that read the error status, consider the affect on the system when errors are detected and program error processing accordingly. For example, even the detection of a minor error, such as Battery replacement during operation, can affect the system depending on how the user program is written.
  • Page 32 SD Memory Cards • Insert the SD Memory Card all the way. • Do not turn OFF the power supply to the Controller during SD Memory Card access. The files may be corrupted. 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.
  • Page 33 Concepts  EMC Directive OMRON devices that comply with EC 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 34 The NJ-series Controllers comply with the following shipbuilding standards. Applicability to the ship- building 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.

    3 Operation and Configuration Extra Functions 3-7-1 Hysteresis An encoder can come to rest at a particular position and then “oscillate” around this position. This state means that the Counter Value fluctuates around a particular value. If, for example, a Range Limit is in this area of fluctuation, the corresponding Range would become active and inactive in the rhythm of these fluctuations.

  • Page 94: Initial Counter Value

    3 Operation and Configuration 3-7-2 Initial Counter Value Every Counter has device variables for CJ-series Unit for setting (double word) the initial Counter Val- ues. The settings for these variables are transferred from the CPU Unit to this unit when the Unit restarts or the Controller is reset, including when the power is turned ON.

    4 Exchanging Data with CPU Memory Allocation 4-2-1 Memory Mapping The data to be used when operating in Range mode or Comparison mode are allocated to any DM or EM Area (bank 0). This allocation method is called extended allocation. For details, refer to 4-2-2 Allo- cating Ranges and Comparison Data.

  • Page 102: Allocating Ranges And Comparison Data

    4 Exchanging Data with CPU Data assigned to Counters 1-4 can be allocated to any DM or EM address. When this data is over- lapped (duplicated), the Unit treats the overlap as a warning and "*_IABlkOverlapSta" (IA Blocks overlap) becomes 1. But this is not an error. In other words, by defining one range data or compari- son data and setting the same indirect address in more than one location (k1 = k2), that data can be shared by more than one Counter.
