PURPOSE:To eliminate the necessity for adjusting a servo control device and to facilitate switching and changing a characteristic curve by providing a means for digitally converting the displacement amount of a slider, means for storing plural quantities of output characteristic curves for the displacement amount and a means for enabling a desired characteristic curve to be selected out of the above-mentioned characteristic curves. CONSTITUTION:Plural displacement and output characteristic curve data, assigned by a selecting circuit 6 with the digital displacement amount of a slider 2a serving as an address, are stored in a ROM5. A CPU4 reads the displacement amount of the slider 2a as a digital value from an A/D converter while it reads displacement amount and output characteristic curves, assigned by a user, also from the selecting circuit 6. Address data, determined by both the slider 2a and the selecting circuit 6, are input as a speed command to a D/A converter 7 to perform a fine control of a servo motor M. |
