Abstract
PURPOSE: To standardize control circuit and to improve availability, by including information corresponding to the output from the servo motor in a connector for coupling the servo motor and the control circuit.
CONSTITUTION: Upon provision of a forward rotation command 1 or a reverse rotation command 2, transistors Q1, Q4 or Q2, Q3 are turned ON to feed current in forward or reverse direction to a servo motor M. When the level of current detected through a resistor R7 exceeds over a maximum current level, output of a comparator 5 goes to L-level so as to disable rotation of the servo motor M. Since a connector CN for connecting the servo motor and the control circuit is switched corresponding to the output of the servo motor M, maximum current level can be set corresponding to the output of the servo motor M.
