Abstract

Viene proposta una disposizione per la regolazione di un dispositivo di azionamento comandato da invertitori con un circuito intermedio a tensione continua (7) che alimenta in comune più motori (3). A tale scopo, mediante una disposizione di rilevamento adatta (da 15 a 18), il valore della tensione continua del circuito intermedio viene misurato e trasmesso a potenziale zero alle unità a invertitore (1) associate ai singoli motori. Un microelaboratore (2) previsto in ciascuna unità a invertitore (1) corregge in base al valore di tensione trasmesso il segnale di pilotaggio per il relativo invertitore.(Figura 1).
