To provide a servo controller which does not cost much in manufacture, is small-sized, and has a shorter control cycle of an object to be controlled than a conventional one.
The servo controller 50 is provided with: a current supply part 15 for supplying a driving part 20 with driving current so as to drive the object to be controlled; a detection part 17 for detecting at least a driving current value; and a logical operation part 51 for inputting a current command in which the driving current for controlling a driving velocity of the driving part 20 is defined so as to move the object to be controlled to a desired position, inputting the driving current value fed back by the detection part 17, compensating the current command by a digital logic system on the basis of the driving current value, and outputting the compensated current command to the current supply part 15.
