A servo-controller, where, in order to enable a second mobile member to carry out a certain programmed sequence of operations corresponding to the moving position, speed, pressure, force or torque of a first mobile member, the said moving position speed, pressure, force or torque of the first mobile member is detected as an analog signal, which is compared with each of various level signals sorted stepwise and identified so as to operate the corresponding relays in succession; where the successive actions of these relays is such that control is effected by a first switch group (on a pin board connection panel), a second switch group (for carrying out switching operations for the step subsequent to each member of the first group) and a third switch group for selecting the said level signal; a remainder derived from the difference signal between set signals passed through these first and second switch groups, respectively, is multiplied by another remainder derived from the difference signal between the said analog signal and a level signal passed through the third switch group and the resultant product is combined additively with the set signal passed through the first switch group, so that the resultant sum is applied as an input signal to a servo-amplifier so as to control the motion of the said second mobile member.
