PURPOSE: An actuator control apparatus is provided to prevent malfunction in advance due to a nose signal by skipping a noise signal under 0.2V which is included in a control signal. CONSTITUTION: An actuator(10) comprises an upper limit switch(11), a lower limit switch(12), and a potentiometer(13). A power unit(21) changes an external AC power into a constant DC power. A control unit(30) provides a control signal. A buffer amplifier(22) filters the control signal of the control unit. A MICOM(40) amplifies the detection signal of the potentiometer by a constant current. An auto setting switch(70) sets the operation range of an actuator within 0-100% A mode selector(50) respectively sets the direction and operation rage of the motor respectively. A drive unit(60) controls the operation of the motor(M). The control unit comprises a current / voltage control signal mode selection switch(31). |
