CHAPTER 1 INTRODUCTION

1.3 Outline of product

SJ-LW is LonWorks communication board for SJ300/L300P series inverter.

SJ300/L300P series inverter can get to connect another devices via LonWorks when install SJ-LW. SJ-LW is possible to connect for all models of SJ300/L300P series.

The SJ-LW option card communi cate s a ccording to t he L on Works P roto col Stan dard ANS I/EIA 709. 1- A -1999. This means that it can communicate with all LonWorks nodes that comply with this standard, but it does not necessarily mean that all services available in the LonWorks standard are supported. The “LonMark Functional Profile: Variable Speed motor Drive” (doc no. 6010_11) is supported.

In a control system the option board will act as a node that can be read and written to, from any other LonWorks node that has SNVT’s that corresponds to the one on SJ-LW.

(Note) RS485 communication function is disabled by installing SJ-LW to the inverter.

For detailed information about recommended cables for a LonWorks network, please see the FTT-10A Free Topology Transceiver User’s Guide (doc.id.078-0156-01F) available at http://www.echelon.com Below are some recommended cables :

-Belden 85102, unshielded

-Belden 8471, unshielded

-Level IV 22AWG, unshielded

-JY (St) Y 2x2x0.8, shielded

-TIA568A Cat.5 24AW G

Note) To be able to communicate in a noisy environment, and to fulfil all EMC-requirements, it’s important that a shielded cable is used, and that proper grounding is provided.

3.3 Wiring note

1.Installing the cable to Network connector must be done after checking the power supply off.

2.Wiring should not have bare cables exposed between connector contacts.

3.Network cables should be fixed without tension. Cables fixed under tension have potential of causing a

communication fault by to be removed a connector.

4.Ensure external emergency stop measures are taken to stop the inverter, in the event of a network fault.

(a) Remove the Power supply of the Inverter when the network master detects a communication fault. (b) When the m aster d etects a com m unicat ion f ault, turn on the intellig ent input terminal which would be allocated (FRS), (RS) and/or (EXT) function.

CHAPTER 4 SETTING

4.1 Setting of controlling frequency and start/stop commands

The Hitachi SJ300/L300P inverters can be configured to take reference set-points and commands from several different locations. Re fer to the ta ble below for info rmation of how t o configu re the inve rter so that the Lonworks controls frequency and the commands.

4.2 Network termination (S2)

The SJ-LW option board provides internal termination of the LonWorks network. To enable/disable the termination a switch (S2) is used. See Figure 1-1 for location of the switch. The following table explains the possible switch-settings :

Switch-position Termination type FT Free topology termination enabled NO Termination disabled BUS Bus topology termination enabled

For more information about termination, see the FTT-10A Free Topology Transceiver User’s Guide (doc.id.078-0156-01F) available at http://www.echelon.com

Note) Risk of equipment damage exists. The SJ-LW contains ESD (Electrostatic Discharge) sensitive parts that can be damaged if you do not follow ESD control procedures. Static control precautions are required when handling the adapter.

4.3 Service pin (S1)

The SJ-LW option board provides one Service pushbutto n (S1 ), which i s used d uring the i nstalla tion pha se to identify the node. See Figure 1-1 for location of the pushbutton. The SJ-LW is installed in a LonWorks network using any standard LonWorks installation tool. (i.e. “LonMaker for Windows” from Echelon).

4.4 Baudrate

The SJ-LW has a fixe d bau dr at e of 78k bps (F TT -10 A).
