Abstract
A drive control apparatus for controlling a plurality of control variables of at least one electrically powered axle of a processing machine, such as an injection molding machine. Multivariable control means including internal signal processing and date storage means for an open and closed-loop control of phase angle, current input and velocity are dominating process computer means for a lag-free control of the control variables.
