PURPOSE:To obtain a control apparatus with the digital servo-mechanism of a wide controllable range, by changing a sampling cycle according to the rotation command signal of a motor. CONSTITUTION:Output pulse from an encoder 2 interlocked with the rotation of a motor 1 is computed by a counter 3. In the meantime, by a timing signal generating circuit 8, sampling signal is applied to a CPU6 every sampling cycle. The CPU6 is performed arithmetic according to pulse number computed by the counter 3 and timing signal, and the output of control signal is directed to a driving circuit 4. By the CPU6, it is discriminated whether rotation command signal is generated at a high speed or at a low speed, and the output of speed signal is directed to the timing signal generating circuit 8. By the signal, the cycle of sampling signal is changed through the timing signal generating circuit 8. |
