PURPOSE:To make a motor-driven suspended object device to make a produced delicate expression by operating a guide rope wound around a pulley shaft fitted with a rotary encoder an commands from a console panel which is electrically connected with the rotary encoder and pulley shaft and receives signals from the encoder. CONSTITUTION:When a guide rope 10 is pulled upon confirming that a rope side indicating lamp 13 is turned on by means of a command from a console panel 9, a pulley 4 starts to rotate and rotary encoders 3 input signals corresponding to rotating speeds to the console panel 9. When the rope 10 is stopped, the signals from the encoders 3 are also stopped. The panel 9 outputs an operating command, speed signal, and stopping command to a servo driver 8 on the basis of the signals. A servo motor 6 drives a traction drum 5 on the basis of the commands and operates a baton 1. When the baton 1 is operated, the position and speed of the baton 1 are detected by means of a rotary encoder 3B and resolver 7 and inputted to the console panel 9. The panel 9 compares the position and speed signals of the baton 1 with the position and speed signals of the guide rope and controls the baton 1 so that the baton 1 can be moved faithfully to the movement of the guide rope. |
