PURPOSE:To make it possible to maintain the optimum servo control regardless of the variation in motor load. CONSTITUTION:Output data from a controller 1 are detected through a data detecting circuit 2. Control signals CS1 from the data detecting circuit 2 are fed to a bias select switch 4. An adder 3 is fed with output data from the controller 1 and a DC bias voltage selected through the bias select switch 4. The output voltage from the adder 3 is impressed on a capstan motor 5. |
