PURPOSE: To automatically balance a stand that has been manually balanced, through the provision of control circuits and redress circuits for driving an angular moment correction means until the balance of axes found unbalanced with a balance sensor. CONSTITUTION: A balanceable stand is provided for its total balance with three redress circuits R1', R5' and R6' and three control circuits S1 to S3. The control and redress circuits materially work through a microprocessor μP in a controller 11 connected to the stand. The redress circuit R1' serves to automatically balance an axis A6 by means of an X-Y slide device. The control circuits S1 to S3 serve to balance axes A2, A3, A4 and A5. The control circuit S1 moves a load along the axis A6 only by a predetermined slide length L6 to detect the actual load position in the axis A6 with a position detector. The control circuits S2 and S3 move balance weights 6 and 7 only by slide lengths L2 and L3 detected through electric drive. |
