Abstract
PURPOSE: To perform a motor drive control in accordance with each division by discriminating and together with dividing a motor stop range, speed change control range and maximum speed driving range according with an operation of one each potentiometer.
CONSTITUTION: When a potentiometer 1 is set at an "off" position, a potential of a variable tap 1c is lower than an established voltage of the first comparison circuit 4, therefore an output signal of the comparison circuit is (L) and a transistor 7 for motor starting is being broken off. Successively the potentiometer is operated and entered into a speed change control range, then a potential of a tap lc becomes higher than an established voltage of the first comparison circuir 4, and by (H) signal of the comparison circuit 4 a transistor 7 for motor starting is made "on" to start a motor 8. At this time a potential of the tap 1c is lower than an established voltage of the second comparison circuit 5, and as a transistor 10 is being "off" a contact 9b of a relay 9 is closed and a motor 8 is speed change controlled by a pulse generating circuit 2 and an output amplifing circuit 3.
