    DESCRIPTION The FR-A5NP option unit consists of two circuit boards. The option unit is mounted in option port #3 on the inverter unit. The inverter top cover must be removed to install the option unit. After installation, the top cover is reinstalled and connection to the PROFIBUS-DP bus is completed through a connector accessible through the top cover.

    2. INSTALLATION Remove the drive cover following the inverter instruction manual and install the option unit using the following procedure: 2.1 Pre-installation Checks (1) Check the inverter type. Use the option unit only with an FR-A500(L)/F500(L) series inverter. Do not use it with any other series (e.g. A200E, A200, A100, Z and F series).

  • Page 10 INSTALLATION (5) Construct a short cable to connect the network to the inverter. On one end of the cable, install a connector compatible with the network. On the other end, install a DB9-style male connector. Make sure the cable can support 12.0 Mbps communications (as specified in the EEIA-RS- 485 standard).
  • Page 11 RS-485 signal A and the RXD/TXD- to B’. Some PROFIBUS-DP implementations confuse these two signals. If you are having trouble establishing communications from the FR-A5NP to your PROFIBUS-DP master, verify that the proper data signal assignments are made. It may be necessary to swap these two signal lines.

  • Page 14: Connecting To The Network

    INSTALLATION 2.3 Connecting To The Network (1) Make sure the inverter is at rest with power off and the option unit is mounted in the inverter. Connect the PROFIBUS cable created in section 2.2 to the network. (2) It is now safe to apply power to the inverter and run it in PU, external, or net mode, provided that any external inverter control cables in addition to the PROFIBUS network cable are installed correctly.

    OPERATION One way to ensure activity is to configure the PROFIBUS master to enable response monitoring. Alternatively, you can have the PROFIBUS master issue a null command (Command Word 1 = 0) or any other command. Refer to Section 5. 3.3 Functions Available in the Operating Modes The functions available to the drive depend on the operating mode.

    Network Communication Coordination using the FR-A5NP PROFIBUS-DP Option Module. When a command message is sent to the inverter via the FR-A5NP, the inverter enters a “busy” mode while the command is executed. When a command message is sent while the inverter is in “busy” mode, that command is stored in a queue in the FR-A5NP until the inverter finishes execution of the current command and exits “busy”...
