User manual HITACHI SJ-EN

[. . . ] 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 MODBUS services and functions are supported. Detailed description of the available functionality is provided in Chapter 4 of this manual. [. . . ] 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. Otherwise undesirable inverter behavior may occur. CAUTION: Certain parameter data ranges vary depending on model and capacity. The SJ-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. 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.

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. 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. There are four holes on the corners of the option board. 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. Insert the board fully into the connector. 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. [. . . ] 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 board installed in option slot 2. The number to the right of the decimal point indicates the drive status at the time of trip, as follows: EXX. 0 EXX. 3 EXX. 6 At reset At constant speed At starting EXX. 1 EXX. 4 EXX. 7 At stop During acceleration During DC injection braking EXX. 2 EXX. 5 EXX. 8 During deceleration f0 Stop During overload restriction The digit immediately to the left of the decimal point has the following meaning: Code Trip Name Cause Check Remedy Defective connection Connectors (plugs & jacks), cable That PC is powered on and connected Verify proper Ethernet setup of SJ-EN and master device Replace or repair; press STOP/RESET on inverter keypad Press STOP/RESET on inverter keypad EX0.
