  • Page 3: Safety Precautions

    SAFETY PRECAUTIONS (Read these precautions before using this product.) Before using this product, please read this manual and the relevant manuals carefully and pay full attention to safety to handle the product correctly. The precautions given in this manual are concerned with this product only. For the safety precautions of the programmable controller system, refer to the MELSEC iQ-R Module Configuration Manual.
  • Page 4 [Design Precautions] WARNING ● Configure safety circuits external to the programmable controller to ensure that the entire system operates safely even when a fault occurs in the external power supply or the programmable controller. Failure to do so may result in an accident due to an incorrect output or malfunction. (1) Emergency stop circuits, protection circuits, and protective interlock circuits for conflicting operations (such as forward/reverse rotations or upper/lower limit positioning) must be configured external to the programmable controller.
  • Page 5 [Design Precautions] WARNING ● Do not write any data to the "system area" and "write prohibited area" of the buffer memory in the module. Also, do not use any "use prohibited" signals as an output signal from the CPU module to each module.
  • Page 6 [Security Precautions] WARNING ● To maintain the security (confidentiality, integrity, and availability) of the programmable controller and the system against unauthorized access, denial-of-service (DoS) attacks, computer viruses, and other cyberattacks from external devices via the network, take appropriate measures such as firewalls, virtual private networks (VPNs), and antivirus solutions.
  • Page 7 [Wiring Precautions] WARNING ● Shut off the external power supply (all phases) used in the system before installation and wiring. Failure to do so may result in electric shock or cause the module to fail or malfunction. ● After installation and wiring, attach a blank cover module (RG60) to each empty slot and an included extension connector protective cover to the unused extension cable connector before powering on the system for operation.
  • Page 8 [Wiring Precautions] CAUTION ● Individually ground the FG and LG terminals of the programmable controller with a ground resistance of 100 ohms or less. Failure to do so may result in electric shock or malfunction. ● Use applicable solderless terminals and tighten them within the specified torque range. If any spade solderless terminal is used, it may be disconnected when the terminal screw comes loose, resulting in failure.
  • Page 9 [Startup and Maintenance Precautions] WARNING ● Do not touch any terminal while power is on. Doing so will cause electric shock or malfunction. ● Correctly connect the battery connector. Do not charge, disassemble, heat, short-circuit, solder, or throw the battery into the fire. Also, do not expose it to liquid or strong shock. Doing so will cause the battery to produce heat, explode, ignite, or leak, resulting in injury and fire.
  • Page 10 [Startup and Maintenance Precautions] CAUTION ● When connecting an external device with a CPU module or intelligent function module to modify data of a running programmable controller, configure an interlock circuit in the program to ensure that the entire system will always operate safely. For other forms of control (such as program modification, parameter change, forced output, or operating status change) of a running programmable controller, read the relevant manuals carefully and ensure that the operation is safe before proceeding.
  • Page 11 [Operating Precautions] CAUTION ● When changing data and operating status, and modifying program of the running programmable controller from an external device such as a personal computer connected to an intelligent function module, read relevant manuals carefully and ensure the safety before operation. Incorrect change or modification may cause system malfunction, damage to the machines, or accidents.

  • Page 30: Scaling Function

    Scaling Function Normal This function performs the scale conversion on digital values within a specified range between a scaling upper limit value and a scaling lower limit value. This function helps reduce the time taken for creating a scale conversion program.

  • Page 32 Precautions • When the scaling function is used, the digital value can be set to a value out of the range between the scaling upper limit value and scaling lower limit value (in the dotted lines in the I/O conversion characteristic graph) before being scaled. However, use the scaling function within the range of the analog output practical range (in the solid line in the I/O conversion characteristic graph).

  • Page 33: Shift Function

    Shift Function Normal This function allows adding the set input value shift amount to the digital value. The analog output value reflects the change in the input value shift amount on a realtime basis. Therefore, fine adjustment can be easily performed when the system starts. Operation When the D/A conversion is performed on the digital value, the value obtained by adding 'CH1 Input value shift amount' (Un\G480) to 'CH1 Digital value' (Un\G460) is used for the D/A conversion.
  • Page 34 Precautions • Based on the digital value obtained after the shift-and-add processing, the warning output function, scaling function, and rate control function are executed. • When the value obtained by adding 'CH1 Input value shift amount' (Un\G480) to 'CH1 Digital value' (Un\G460) is out of the digital setting range, a digital value setting range error (error code: 191H) occurs and the corresponding check code is stored in 'CH1 Set value check code' (Un\G400).

  • Page 37: Rate Control Function

    1.10 Rate Control Function Normal This function prevents the sudden change of the analog output value by limiting the increment/decrement of the analog output value per conversion cycle. Operation When the setting value of 'CH1 Digital value' (Un\G460) is changed, if the difference between the previously set digital value and the newly set digital value is larger than the digital limit values below, the rate control function will be executed.
  • Page 38 Operation example of the rate control function The following figure and table show an operation example when the rate control function is used for CH1 to CH3. Setting item CH1 setting CH2 setting CH3 setting CH4 setting D/A conversion enable/disable setting Enable Enable Enable...
  • Page 39 Change of digital value during the rate control When the digital value is changed again during the rate control, the rate control will continue until a new digital value is output in analog. In this case, setting the digital value that reverses the direction of increase or decrease changes the digital limit value used for the rate control depending on the direction of increase/decrease.
  • Page 40 Relationship between CPU module status and analog output When the CPU module status is changed, the operation of the rate control function varies depending on the setting of the analog output HOLD/CLEAR function as shown below. ■When the analog output HOLD/CLEAR function is set to CLEAR If the status of CPU module changes from RUN to STOP (error), the rate control stops and offset value is output in analog.
