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).A provision is proposed for regulating an actuator device controlled by inverters with an intermediate DC voltage circuit (7) which supplies several motors in common (3). For this purpose, by means of a suitable detection arrangement (15 to 18), the value of the DC voltage of the intermediate circuit is measured and transmitted at zero potential to the inverter units (1) associated with the individual motors. A microcomputer (2) provided in each inverter unit (1) corrects the driving signal for the relative inverter on the basis of the voltage value transmitted (Figure 1).
