Introduction to Varia ble-Frequency Drives Getting Star ted 1–12 Intr oduction to V ariable-Frequenc y Drives The Purpose of Motor Speed Contr ol for Industry Hitachi in verters provide speed control fo r 3-phase A C induction motors. Y ou connect A C power to the in verter , and connect the in verter to the motor .
L200 Inverter Getting Star ted 1–13 T orque and Constant V olts/Hertz Operation In the past, A C variab le speed driv es used an open loop (scalar) technique to control speed. The constant-volts-per -hertz operation maintains a constant ra tio between the applied voltage and the applied frequenc y .
Introduction to Varia ble-Frequency Drives Getting Star ted 1–14 In ver ter Output to the Motor The A C motor must be connected only to the in ve rter’ s output terminals. The output terminals are uniquely labeled (to dif ferentiate them from the input terminals) with the designations U/T1, V/T2, and W/T3.

CE–EMC Installation Guidelines Appendix D D–2 CE–EMC Installation Guidelines Y ou are required to satisfy the EMC directi ve (89/336/EEC) when using an L200 in verter in an EU country . T o satisfy the EMC directive and to comply with standard, follow the guidelines in this section.
L200 Inverter Appendix D D–3 4. T ake measures to minimize interference that is frequently coupled in through installa- tion cables. • Separate interfering cables with 0.25m minimum from cables susceptible to inter- ference. A partic ularly critical point is laying para llel cables over longer distances.
CE–EMC Installation Guidelines Appendix D D–4 L200 in verter designed for use in Europe (–xxxLFEF/xxxHFEF models) ha ve built-in line filters. In the e vent your applicati on needs additional f iltering, the following diagrams show control panel mounting and wiring e xamples for different f ilter t ypes.

Een belangrijk punt na aankoop van elk apparaat Hitachi L200 (of zelfs voordat je het koopt) is om de handleiding te lezen. Dit moeten wij doen vanwege een paar simpele redenen:
Als u nog geen Hitachi L200 heb gekocht dan nu is een goed moment om kennis te maken met de basisgegevens van het product. Eerst kijk dan naar de eerste pagina\'s van de handleiding, die je hierboven vindt. Je moet daar de belangrijkste technische gegevens Hitachi L200 vinden. Op dit manier kan je controleren of het apparaat aan jouw behoeften voldoet. Op de volgende pagina's van de handleiding Hitachi L200 leer je over alle kenmerken van het product en krijg je informatie over de werking. De informatie die je over Hitachi L200 krijgt, zal je zeker helpen om een besluit over de aankoop te nemen.
In een situatie waarin je al een beziter van Hitachi L200 bent, maar toch heb je de instructies niet gelezen, moet je het doen voor de hierboven beschreven redenen. Je zult dan weten of je goed de alle beschikbare functies heb gebruikt, en of je fouten heb gemaakt die het leven van de Hitachi L200 kunnen verkorten.
Maar de belangrijkste taak van de handleiding is om de gebruiker bij het oplossen van problemen te helpen met Hitachi L200 . Bijna altijd, zal je daar het vinden Troubleshooting met de meest voorkomende storingen en defecten #MANUAl# samen met de instructies over hun opplosinge. Zelfs als je zelf niet kan om het probleem op te lossen, zal de instructie je de weg wijzen naar verdere andere procedure, bijv. door contact met de klantenservice of het dichtstbijzijnde servicecentrum.
