PURPOSE:To attain speed control based upon respectively optimum speed control curves under various conditions by storing a simple table. CONSTITUTION:A common item which is not changed by an operating condition is taken out by using a speed control curve non-dimensionally and normally, previously calculated and stored to calculate an objective control speed easily. Data inputted from an initial constant input part 1 is applied to an initial arithmetic part 2 and the operated result is applied to a section arrival value arithmetic part 4 together with the data obtained from a positioning command value input part 3. The operated result of the arithmetic part is applied to a speed arithmetic part 5 together with data obtained from an area deciding part 6. The output of the speed arithmetic part 5 is applied to a motor 7 through a differential amplifier 8. Since data applied in each normal use are only the practical maximum speeds close to an objective distance and the using status, the operating speed is extremely high and therefore the response speed is also high. |
