PCT No. PCT/JP85/00377 Sec. 371 Date Mar. 4, 1986 Sec. 102(e) Date Mar. 4, 1986 PCT Filed Jul. 4, 1985 PCT Pub. No. WO86/00730 PCT Pub. Date Jan. 30, 1986.An acceleration and deceleration system smoothly controls acceleration and deceleration of an electric motor for driving a movable member of a machine tool or a robot. The acceleration and deceleration system has a linear acceleration and deceleration circuit (3) for receiving interpolation data issued from a pulse distributor (5) and effecting a linear acceleration and deceleration computation on the received data, and an exponential acceleration and deceleration circuit (4) for receiving an output signal from the linear acceleration and deceleration circuit (3) and effecting an exponential acceleration and deceleration computation on the output signal, the circuits (3), (4) being connected in series with each other. The exponential acceleration and deceleration circuit (4) reduces abrupt changes of the controlled speed which are a drawback of the linear acceleration and deceleration circuit (3) prevent shocks from being produced when an axis starts moving and is decelerated thereby providing smooth and accurate acceleration and deceleration control.
