PURPOSE:To make the same adjustment by detecting the resistance value of a variable resistance which attenuates and output an input analog signal through a potentiometer and then controlling a slider by an output corresponding to the varying speed of the output of the potentiometer. CONSTITUTION:When a slider 1-2 is moved with a manual knob 1-3, the output of the potentiometer 1-4 is read in a memory 3 to record its position and varying speed successively. In this case, a switching circuit 5 is turned off and a variable resistance 101 attenuates and outputs an input signal. For control by the same pattern as the last one, when a control start signal is applied to the memory 3, the memory 3 outputs a command value to a servoamplifier 4 and it is compared with the output of the meter 1-4 to apply the result to a motor. Then, the input signal is attenuated and outputted according to the same pattern with the last manual adjustment pattern of the resistance 1-1. |
