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. Even though the board uses the MODBUS/TCP, this does not necessarily mean that all MODBUS services and functions are supported. Detailed description of the available functionality is provided in Chapter 4 of this manual. The board will act as a MODBUS/TCP slave that can be read from and written to over the Ethernet network from a MODBUS/TCP master device. It will not initiate communication with other devices on the network. It will only respond to requests from a master device. The SJ/L-EN will allow a user to control the operation of the inverter, monitor its operation, and modify parameters.

Before using this product, please read this manual and the relevant inverter manual, and be sure to follow all safety precautions noted therein. After unpacking the SJ/L-EN board, carefully inspect it for any defect or damage, and be sure all parts are present.

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.

CAUTION: Indicates a potentially hazardous situation that, if not avoided, can result in minor to moderate injury, or serious damage to the product. The situation described in the CAUTION may, if not avoided, lead to serious results. Important safety measures are described in CAUTION (as well as WARNING), so be sure to observe them.

HIGH VOLTAGE: Motor control equipment and electronic controllers are connected to hazardous line voltages. When servicing drives and electronic controllers, there may be exposed components with housings or protrusions at or above line potential. Extreme care should be taken to protect against shock. Stand on an insulating pad and make it a habit to use only one hand when checking components. Always work with another person in case an emergency occurs. Disconnect power before checking controllers or performing maintenance. Be sure equipment is properly grounded. Wear safety glasses whenever working on electronic controllers or rotating machinery.

WARNING: This equipment should be installed, adjusted, and serviced by qualified electrical maintenance personnel familiar with the construction and operation of the equipment and the hazards involved. Failure to observe this precaution could result in bodily injury.

WARNING: HAZARD OF ELECTRICAL SHOCK. DISCONNECT INCOMING POWER BEFORE WORKING ON THIS CONTROL.

WARNING: Wait at least five (5) minutes after turning OFF the input power supply before performing maintenance or an inspection. Otherwise, there is the danger of electric shock.

WARNING: Do not install or remove the SJ/L-EN Ethernet module while the inverter is energized. Otherwise there is the danger of unpredictable inverter operation.

WARNING: Never modify the unit. Otherwise, there is a danger improper and/or unpredictable inverter operation.

CAUTION: Be sure to secure the SJ/L-EN module with the supplied mounting screws. Make sure all connections are made securely; otherwise there is danger of a loose connection and unpredictable operation.

CAUTION: Alarm connection may contain hazardous live voltage even when inverter is disconnected. When removing the front cover for maintenance or inspection, confirm that incoming power for alarm connection is completely disconnected.

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. 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 through network commands.

CAUTION: When configuring parameters with the standard keypad, the inverter checks for and inhibits invalid parameter combinations when the STR key is pressed. The SJ/L-EN bypasses this check, so it is incumbent on the user to make sure invalid configuration parameters or combinations are not sent through network commands. Otherwise undesirable inverter behavior may occur.

CAUTION: Certain parameter data ranges vary depending on model and capacity. The SJ/L-EN does NOT check to make sure these data are within range. It is incumbent on the user to make sure data for these parameters is within range for the specific model and rating. These parameters are noted in the parameter tables in the Appendix. Otherwise undesirable inverter behavior may occur.

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. Otherwise, the SNAP-TRACK can be affixed directly to a flat surface using double-sided tape, with screws, or other mounting method of your choice.

Make sure the inverter is powered down. Connect the SJ/L-EN to the inverter using the 2 ft. long RJ11 Male/Male cable supplied. Plug one end into the RJ11 Jack on the SJ/L-EN marked “SERIAL”. The other end of this cable plugs into the RJ45 connector on the inverter. In the case of the SJ200, the keypad and male/male adapter on the inverter must be removed, and the cable will plug into the RJ45 Jack on the front of the SJ200.

Note: Even though the communication connector jack on the inverter is RJ45 and the 2 ft. cable plug is RJ11, the RJ11 plug will fit into the center of the RJ45 jack and connect properly.

The SL/L-EN requires 24 VDC to be supplied to it, via the terminals marked “+ 24 V −” on the lower left of the board. This power may be supplied from the inverter in the case of the L100 and SJ100, where 24 VDC is available between terminals P24 and L. In the case of the L200 and SJ200, an external 24 VDC power supply must be provided by the user. The terminal marked GNDC is an additional grounding point, and may be used to terminate the shield lead if shielded cable is used to connect to the SJ/L-EN.

The ethernet network cable will plug into the RJ45 jack on the SJ/L-EN marked “ETHERNET”.

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.

•LINK (GREEN) – This LED is ON when the SJ/L-EN is receiving valid Ethernet pulses.

•ACTIVITY (GREEN) – This LED is ON whenever there is Ethernet traffic in the cable.

•ERROR (RED) – This LED will be ON if the SJ/L-EN has failed due to a hardware watchdog timeout, or the Ethernet communications has been absent for the software watchdog timeout period.

Two LEDs near the right edge of the board:

•RTS – This LED indicates communication between the SJ/L-EN to the inverter through the serial port.

•TXD – This LED indicates communication from the SJ/L-EN to the inverter through the serial port.

•RXD – This LED indicates communication to the SJ/L-EN from the inverter through the serial port. (All three of these LEDs should be rapidly blinking; if not, there may be a problem with the connection.)
