Abstract

PURPOSE:To simultaneously control the position and the speed of a DC motor only by a signal from an encoder without using a tachometer generator by conducting a logic operation by the detection signal and the position instruction signal from an encoder and a speed instruction signal. CONSTITUTION:The signal from an encoder 3 provided at a DC motor 1 and the position instruction signal from an instruction unit 7 are logically calculated in a logic circuit 8, which thereupon generates a position drive signal to control through a DA converter 9, an AV converter 10 and a drive circuit 21 transistors Tr1-Tr4. The signal from the encoder 3 and the speed instruction signal from the instruction unit 7 are logically calculated in a logic circuit 12, which thereupon generates a speed drive signal to control through an FV converter 13 the transistors Tr1-Tr4 to thereby drive the motor 1. Since the position and speed of the motor are controlled only by the detection signal of the encoder 3 as described above, it can simplity the configuration without using a tachometer generator.
