  • Page 3: Preface

    Preface Thank you for purchasing our SX-bus Communications Card OPC-G1-SX. Mounting this communications card on your FRENIC-MEGA allows you to connect the FRENIC-MEGA to a Fuji programmable logic controller MICREX-SX series via SX bus and control it as a slave unit using run and frequency commands, and accessing function codes.
  • Page 4 Installation and wiring • Before starting installation and wiring, turn OFF the power and wait at least five minutes for inverters with a capacity of 22 kW or below, or at least ten minutes for inverters with a capacity of 30 kW or above.
  • Page 5 Disposal • Treat the communications card as an industrial waste when disposing of it. Otherwise injuries could occur. Others • Never modify the communications card. Doing so could cause an electric shock or injuries. Icons The following icons are used throughout this manual. This icon indicates information which, if not heeded, can result in the product not operating to full efficiency, as well as information concerning incorrect operations and settings which can result in accidents.

    Chapter 3 INSTALLATION AND REMOVAL OF THIS COMMUNICATIONS CARD Before starting installation and wiring, turn OFF the power and wait at least five minutes for inverters with a capacity of 22 kW or below, or at least ten minutes for inverters with a capacity of 30 kW or above. Make sure that the LED monitor and charging lamp are turned OFF.

  • Page 11: Removing The Communications Card

    Fit the positioning cutout of the communications card over the tab on the inverter to determine the mounting position. Insert connector CN1 on the communications card into the corresponding port on the inverter's control PCB. Note: Be sure to follow the order of Inserting CN1 first may lead to insufficient insertion, resulting in a contact failure.

  • Page 12: Chapter 4 Wiring And Cabling

    Chapter 4 WIRING AND CABLING • Before starting installation and wiring, turn OFF the power and wait at least five minutes for inverters with a capacity of 22 kW or below, or at least ten minutes for inverters with a capacity of 30 kW or above. Make sure that the LED monitor and charging lamp are turned OFF.
  • Page 13 Figure 4.1 shows the basic connection diagram. When connecting the communications card to an SX bus, observe the following precautions. Precautions for SX bus connection (1) Be sure to use SX-bus dedicated cables. Model: NP1C-P3 (0.3 m) to NP1C-25 (25 m) For details about the cable specifications, refer to the MICREX-SX user's manual (Hardware version) which can be downloaded for free from our website at: http://www.fujielectric.com/...

  • Page 14: Wiring To Inverter

    Wiring to Inverter Route the SX-bus cables as far from the wiring of the main circuit as possible. Otherwise electric noise may cause malfunctions. Pass the SX-bus cables between the control circuit terminal block and the front cover. • For inverters with a capacity of 22 kW or below In the case of 0.4 kW •...

  • Page 15: Chapter 5 Configuring Inverter's Function Codes For Sx-Bus Communication

    Chapter 5 CONFIGURING INVERTER'S FUNCTION CODES FOR SX-BUS COMMUNICATION Inverter's Function Codes Before starting actual inverter operation, configure the inverter's function codes listed in Table 5.1. It is recommended to configure them before starting SX-bus communication, since an SX-bus network break could occur immediately after the start of communication.

  • Page 16: O31 Display Value

    o31 Display Value o31 displays the actual station address of the communications card which is currently assigned by the connected SX bus. The actual station address may be different from the one configured by the station address switches (RSW1 and RSW2 described in Section 2.2) since the SX bus has priority over those switches. Even writing any data to o31 from the keypad or via SX bus cannot change the actual station address or overwrite the o31 data with the written data.

  • Page 19 The Module insert window appears. Select items as shown below and then click OK. The screen returns to the system definition window as shown below. Check that the inverter FRN-G1 is registered under the System structure in the system definition tree.
  • Page 20 (3) Configuring the I/O group Allocate the module (inverter) in the MICREX-SX CPU. Incorrect allocation of the I/O group disables input/output control from the CPU. In the system definition window, right-click CPU: to display the pull-down menu and then choose Properties..
  • Page 21 The CPU parameters window appears. Double-click the I/O group setting tab to display the window shown below. Click Standard setting, and the FRN-G1 is automatically allocated to the Input and Output. Note: In a multi-processor system, if an individual CPU module has a different control target, configure the I/O group for an individual CPU.
  • Page 22 (5) Configuring the station address switches (RSW1 and RSW2) on the communications card (Refer to Section 2.2). Before accessing the station address switches, make sure that the inverter power is OFF. Use the station address switches to configure the station address of the SX-bus communications card. The station address should be the one that has been registered by Expert.
