Abstract
PURPOSE:To reduce fixing space by absorbing overvoltage and counter voltage through a single resistor, thereby reducing the number of resistors. CONSTITUTION:When rectified output voltage from a rectifier 2 goes to an excessively high level, a transistor Q5 comes conductive by an output signal fed from an overvoltage monitoring circuit 3. Consequently, overvoltage component is absorbed through a resistor R3 and supply voltage for a servo motor 1 is maintained at a constant level. Since a switch SW6 is closed when a D.C. motor is stopped, counter voltage produced in the D.C. motor M is absorbed through the resistor R3. Consequently, overvoltage and counter voltage can be absorbed through the single resistor R3.
