User manual HITACHI SJ-EN

[. . . ] 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. [. . . ] 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-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. CAUTION: Certain parameter data ranges vary depending on model and capacity. It is incumbent on the user to make sure data for these parameters is within range for the specific model and rating. Otherwise undesirable inverter behavior may occur. INVERTER COMPATIBILITY The inverter firmware revision number is embedded within the inverter Manufacturing Number, which can be found on the product nameplate. The SJ-EN Ethernet Interface option board is compatible only with SJ300 and L300P series inverters with Revision Numbers HIGHER than those shown below. XX8KT XXXXX XXXXX ­ for SJ300-xxxXFU 0. 4 kW (0. 5 hp) to 55 kW (75 hp), or L300P-xxxXFU or L300P-xxxXBRM 1. 5 kW (2 hp) to 75 kW (100 hp) XXEMT XXXXX XXXXX ­ for SJ300-xxxXFU 75kW (100 hp) to 150 kW (200 hp), or L300P-xxxXFU or L300P-xxxXBRM 90 kW (125 hp) to 132 kW (175 hp) Note: All inverters in the model number series L300P-xxxXFU2 are compatible with the SJ-EN, regardless of revision number.

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. You can now remove the upper front cover to expose the two option ports inside. Figure 2-3 below shows how to install the option board to option port 1 or 2 of the inverter. Align the board with the port connector in the proper orientation (to the left, when facing the inverter as show). Then align the top two holes with the two screw holes, and the bottom two holes with the two guide posts. Secure the board with the two M3 screws supplied.

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. · ERROR (RED) ­ This LED will be ON if the SJ-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: · TXD ­ This LED indicates communication from the SJ-EN to the inverter through the option port. · RXD ­ This LED indicates communication to the SJ-EN from the inverter through the option port. (These two LEDs may appear blinking or may appear steady ON due to the high blink rate. ) Page 11 of 38 Chapter 2 NOTES: Page 12 of 38 Chapter 3 Chapter 3 ­ Configuration Install NetEdit3 Software NetEdit3 Software is provided on the CD-R enclosed with the SJ-EN option board. [. . . ] · WRITE SINGLE REGISTER (06) ­ This function will write to a single holding register in the inverter. · WRITE MULTIPLE REGISTERS (16) ­ This function will write to a block of contiguous registers in the inverter.

Page 17 of 38 Chapter 4 NOTES: Page 18 of 38 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. 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 board installed in option slot 2. [. . . ]
