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.

Un punto importante, dopo l’acquisto del dispositivo (o anche prima di acquisto) è quello di leggere il manuale. Dobbiamo farlo per diversi motivi semplici:
Se non hai ancora comprato il Hitachi L200 è un buon momento per familiarizzare con i dati di base del prodotto. Prime consultare le pagine iniziali del manuale d’uso, che si trova al di sopra. Dovresti trovare lì i dati tecnici più importanti del Hitachi L200 - in questo modo è possibile verificare se l’apparecchio soddisfa le tue esigenze. Esplorando le pagine segenti del manuali d’uso Hitachi L200 imparerai tutte le caratteristiche del prodotto e le informazioni sul suo funzionamento. Le informazioni sul Hitachi L200 ti aiuteranno sicuramente a prendere una decisione relativa all’acquisto.
In una situazione in cui hai già il Hitachi L200, ma non hai ancora letto il manuale d’uso, dovresti farlo per le ragioni sopra descritte. Saprai quindi se hai correttamente usato le funzioni disponibili, e se hai commesso errori che possono ridurre la durata di vita del Hitachi L200.
Tuttavia, uno dei ruoli più importanti per l’utente svolti dal manuale d’uso è quello di aiutare a risolvere i problemi con il Hitachi L200. Quasi sempre, ci troverai Troubleshooting, cioè i guasti più frequenti e malfunzionamenti del dispositivo Hitachi L200 insieme con le istruzioni su come risolverli. Anche se non si riesci a risolvere il problema, il manuale d’uso ti mostrerà il percorso di ulteriori procedimenti – il contatto con il centro servizio clienti o il servizio più vicino.
