Chapter 1 Chapter 1 – General Description The SJ-EN option board is an Ethernet communication interface for the Hitachi SJ300 and L300P series of AC Variable Frequency Inverters. The board can be installed in one of the two available option slots in the inverter. The SJ-EN uses the open MODBUS/TCP communication protocol. It utilizes a 10Base-T physical interface with a 10 Mbps data transfer rate. Even though the board uses the MODBUS/TCP, this does not necessarily mean that all M

Chapter 1 CAUTION: Be sure not to touch the surface or terminals of the SJ-EN Ethernet option board while the inverter is energized; otherwise there is the danger of electric shock. CAUTION: The software lock modes described in the SJ300 inverter manual are NOT supported via the SJ-EN option board. This means that network commands can bypass any software lock settings configured via the inverter keypad. It is incumbent on the user to make sure no safety lockouts are violated thro

Chapter 2 Installing the Option Board Power down the inverter and wait at least five minutes before moving to the next step. Open and remove the lower terminal cover. Confirm that the red CHARGE LED is extinguished and that the DC bus is fully discharged before proceeding further, otherwise there is the danger of electric shock. Then remove keypad from the inverter. You can now remove the upper front cover to expose the two option ports inside. Figure 2-3 below shows how to in

Chapter 2 User Interface The SJ-EN has six LEDs to convey module status and activity. Four LEDs next to the RJ45 connector: • STATUS (GREEN) – This LED will be ON whenever the SJ-EN is receiving proper power from the inverter and the self diagnostics have shown the board to be functioning normally. • LINK (GREEN) – This LED is ON when the SJ-EN is receiving valid Ethernet pulses. • ACTIVITY (GREEN) – This LED is ON whenever there is Ethernet traffic in the cable. • ERRO

Chapter 3 Figure 3-1 NetEdit3 Initial Screen The NetEdit3 software should find and list any SJ-EN attached to the network. If not, just click on “Scan Network”. An entry will appear in the Device List (grid area), with the board details as shown in Figure 3-2. If more than one board is connected in a common network, you will see a line entry for each of them. The “Module Info” and “General Settings” tabs will now also appear next to the “General Help” tab, below the Device List. You

Chapter 4 Chapter 4 – Operation Setting Up the Inverter for Ethernet Network Operation Once the SJ-EN board has been properly configured and connected to a network as described in Chapter 3, it is capable of reading data from and writing data to the inverter. However if it is desired to have either the RUN command and/or the speed reference come from the Ethernet master, you must change two inverter parameters as shown in the following table.

Chapter 5 Chapter 5 – Troubleshooting In general, the first step to troubleshooting should be to inspect the status LEDs on the SJ-EN board, in addition to the inverter operator/keypad display. These will give valuable clues to the nature of the problem. In addition, the inverter operator/keypad will provide diagnostic information for certain types of errors. Error codes for the option boards will have the format of: E6X.X for a board installed in option slot 1, or E7X.X for a boar
