    • A spindle positioning method for high-speed positioning of a spindle by making the best use of the decelerating capability of a spindle motor. When a fixed-position stop command is generated while the operation of the spindle motor is controlled according to speed control, the motor rotation speed is reduced in accordance with the speed control to a speed N lower than or equal to a maximum rotational speed N1, which defines a constant torque region, and a control mode is switched from the speed control mode to position control mode at a point where the rotational speed is reduced to the speed N. Simultaneously, a value specifying the relation between the present position and target stop position of the motor with respect to one revolution of the spindle is set in an error counter as an initial position deviation. To carry out linear acceleration/deceleration control thereafter up to a final stop position, a position feedback quantity Pf is supplied from the position detector to the error counter, to obtain a speed command Vcmd, which is transferred to a speed loop process.

    • A slip frequency control method for induction motors, capable of achieving accurate control and excellent in control response.To effect determination of a slip frequency (fs) and an excitation magnetic flux frequency (.omega.0) by software processing to reduce a control error and a control delay caused if hardware elements are employed for the determination of these parameters, a vector control processor divides, in a speed control routine (101-104), the sum of a slip frequency, obtained by dividing the product of a secondary current command (I2) and a proportional constant (K2) by an excitation magnetic flux command (.PHI.), and a remainder (.alpha.') in the preceding routine by a routine executing frequency (CV), so as to derive a slip amount (A) and a remainder (.alpha.) in the present routine. In a current control routine (201 to 205) executed at intervals of a period shorter than that of the speed control routine, the processor divides the sum of the derived slip amount and the remainder (.beta.') in the preceding routine by the number (n) of execution of the current control, to thereby derive slip distribution data (.omega.s) and a remainder (.beta.) in the present current control routine, and further adds data (.omega.r) indicative of an actual motor speed to the derived slip distribution data, to thereby derive an excitation magnetic flux frequency (.omega.0).

    • Address generators output addresses of transfer data of transfer origin and destination DRAM's. Updating of the transfer addresses from the address generators during execution of DMA is performed based on a CAS signal from a timing signal generator. A delay element delays the CAS signal by a time which is the sum of an access time of the transfer origin DRAM and a data set-up time of the transfer destination DRAM. A transfer data counter counts the number of leading edges of the CAS signal while a RAS signal from the timing signal generator is held active. When a counted value reaches a preset value, the transfer data counter outputs continuous data transfer suspension information to the timing signal generator. With this arrangement, the halt in operation of a CPU due to continuous occupation of a bus is effectively prevented while achieving the increased data transfer rate.
