PROBLEM TO BE SOLVED: To limit a motor current to less than a prescribed value. SOLUTION: This controller is provided with a pulse generator 21, a motor current detecting circuit 33 which converts a current flowing in a motor 2 into a voltage value, a circuit for providing a composite signal of the output of a pulse generating circuit 21 and the output of the motor current detecting circuit 33, a comparator 31 for comparing the composite signal with a reference value, and a circuit for controlling the amount of a current flowing in the motor 2 in accordance with the output of this comparator 31. And setting is so performed that the composite signal may be equal to the reference value when the current flowing in the motor 2 reaches a prescribed value. |
