PURPOSE:To rotate a heavy load at high speed rotation or to accelerate or decelerate various inclinations even if large amount of preset values are not stored by controlling an incremental/decremental counter by a controller, and thereby supplying the preset value of the counter. CONSTITUTION:A read-only memory 20 selects the inclination of a linear acceleration by external signals D1-D2, and supplies a preset value to the third counter 19 in accordance with the output Q of an incremental/decremental counter 21. A J-K flip-flop 18 and the third counter 19 generate an enable of the counter 12 whenever receiving the pulse from an enable controller 17. The pulse period of the counter 11 decides the enable length by the counter 21 and the memory 20 to match the selected acceleration line. |
