Chapter1 Chapter 1 – General Description The SJ/L-EN module is an Ethernet communication interface for the Hitachi SJ200, L200, SJ100 and L100 series of AC Variable Frequency Inverters. The module is mounted externally to the inverter. The SJ/L-EN uses the open MODBUS/TCP communication protocol. It utilizes a 10Base-T physical interface with a 10 Mbps data transfer rate.
Chapter1 SAFETY PRECAUTIONS HIGH VOLTAGE: This symbol indicates high voltage. It calls your attention to items or operations that could be dangerous to you and other persons operating this equipment. Read the message and follow the instructions carefully. WARNING: Indicates a potentially hazardous situation that, if not avoided, can result in serious injury or death.

Chapter1 CAUTION: Be sure not to touch the surface or terminals of the SJ/L-EN Ethernet module while the inverter is energized; otherwise there is the danger of electric shock. CAUTION: The software lock modes described in the inverter manuals are NOT supported via the SJ/L-EN module.
Chapter2 Chapter 2 – Installation and Wiring Orientation to Product Features Figure 2-1 below shows the physical layout of the SJ/L-EN Ethernet module. In particular, note the location of status LEDs and DIP-switches. RTS LED TXD LED RXD LED STATUS LEDs •...
Chapter2 Installing the Module Gently push the SJ/L-EN board into the supplied piece of SNAP-TRACK until it is securely seated. If mounting the SJ/L-EN on a DIN-Rail, attach the two DIN-Rail Clips to the back of the SNAP-TRACK. The assembly can then be affixed to a DIN rail using the clips.
Chapter2 User Interface The SJ/L-EN has seven LEDs to convey module status and activity. Four LEDs next to the RJ45 connector: • STATUS (GREEN) – This LED will be ON whenever the SJ/L-EN is receiving proper power from the inverter and the self diagnostics have shown the board to be functioning normally. •...
Chapter3 Chapter 3 – Configuration Install NetEdit3 Software NetEdit3 Software is provided on the CD-R enclosed with the SJ/L-EN module. This software is required to configure the board. It can also be used to update the SJ/L-EN firmware in the event of a future update. NetEdit3 ®...

Chapter 4 Chapter 4 – Operation Setting Up the Inverter for Ethernet Network Operation Once the SJ/L-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/L-EN board, in addition to the inverter operator/keypad display. These will give valuable clues to the nature of the problem. Refer to the description of the proper LED indications on page 11.
Appendix Appendix – Parameter List Note: Parameters in BOLDFACE can be edited while inverter is in the RUN mode. “RO” means the parameter is Read Only, and “R/W” means the value can be read or written. Please refer to page 32 for a key to other symbols used in these tables.
