<p>This position-controlling apparatus is able to increase servo rigidity when an operation is suspended. When controlling the suspension of an operation at a fixed position, a positional error signal (ER) obtained by the D/A conversion of the output of a present position counter (107) is applied to an operational amplifier (111) as a velocity command, and the deviation of the velocity command from a detected velocity (VS) is applied to a motor (100) through a velocity amplifier (115) and a power amplifier (103). The variable gain of the velocity amplifier (115) is increased by achangeover signal (GCS) when a low-velocity detection circuit (114) judges that the detected velocity is lower than a predetermined velocity. </p> |
