Preface Thank you for purchasing our LONWORKS Interface Card "OPC-LNW." Installing this card on your inverter makes it possible from other LONWORKS devices in the network to issue run and speed commands and monitor the inverter running status, using LONWORKS parameters. It also enables modification and monitoring of the inverter configuration as well as writing to and reading from the inverter's function codes.

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.
If you suspect the product is not working properly or if you have any questions about your product, contact your Fuji Electric representative. - Please check the user's manual of an inverter about an object inverter and a ROM version.
Chapter 3 Basic Functions Service Button The service button is used to commission the LONWORKS interface card to the network. Pressing the button outputs the Neuron ID to the network. Setting inverter's function code o30 to "1" is functionally equivalent to the depression of the service button.
Chapter 4 Installation and Removal Turn the power off and wait for at least ten minutes, before starting installation. Further, check that the LED monitor and charge lamp are unlit, and check the DC link circuit voltage between the P (+) and N (-) terminals to be lower than 25 VDC.
Fit the positioning cutout of the interface card over the tab on the inverter to determine the mounting position. Insert connector CN1 on the interface card into the option connection ports 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.

(2) Wiring to the LONWORKS' terminal block (TERM1) The terminal block uses a pluggable 3-pin connector shown in Figure 5-2. Table 5-1 shows the pin assignment. The applicable pluggable connector is "MVSTBR2.5/3-ST-5.08" manufactured by Phoenix Contact Corporation. 3 2 1 Approx.
Wiring to Inverter Route the wiring of the LONWORKS communications cable as far from the wiring of the main circuit as possible. Otherwise electric noise may cause malfunctions. Route the wires, taking care not to let them go over the control PCB, malfunctions may occur. * Pass the wires from the interface card between the control circuit terminal block and the front cover.
Chapter 6 Function Code Settings Required for LONWORKS Communication To enable run, frequency, and nviXcmd_1 to 5 commands via the LONWORKS network, the inverter requires setting function codes listed in Table 6-1. To enable particular NVs, modify the function codes listed in Table 6-2. To enable other functions, modify them listed in Table 6-3.

To enable other functions, modify function codes listed in Table 6-3. Table 6-3 Function Codes Required for Enabling Other Functions Function Factory Description Setting range Remarks code default o27* Operation selection at occurrence of 0 to 15 Can be specified by LONWORKS communications error UCPT_CblLossMode.

This LONWORKS interface card needs approx. 0.5 second for initialization. Therefore, specifying less than 0.5 second cannot start data transmission from the output NV until approx. 0.5 second elapses. When the interface card is powered up, it transmits all output NVs to validate the latest inverter settings on the LONWORKS network.
