ABSTRACT:
This is a method and associated apparatus for employing a non-regulated voltage input to a DC driver normally outputting a voltage having a curve with a dead band and a variable slope which is a function of the non-regulated voltage input to produce an output to a DC precision positioner from the DC driver which has a constant slope and no deadband. It is particularly useful in pen plotters. The method comprises the steps of, sensing the position of the DC precision positioner and outputting a digital signal indicating the position; calculating the slope of the voltage output from the DC driver; obtaining a pre-established voltage compensation value on a compensation voltage curve which will force the voltage output from the DC driver to attain a value on a voltage curve having a constant slope and no deadband; and, inputting the pre-established voltage compensation value to the DC driver in combination with the non-regulated voltage input whereby the voltage output from the DC driver driving the DC precision positioner attains the value on the voltage curve having a constant slope and no deadband.
