Abstract
From the variables print hammer magnet voltage, print hammer magnet temperature, impact force, and a value derivable from the actual print time, a control voltage, which correspondingly delays an early trigger pulse by means of a variable delay element, is determined in an 'open' control loop. The variables are analogously combined by adding, subtracting, and multiplying the analogue values, and by subsequently forming a weighted sum.
