Title: Induction motor controller
Inventor: TETSUYA YUJI
IPC: H02P23/07
Filed: 1990-09-25
Abstract: PURPOSE:To improve operational efficiency of machine by estimating torque required for traveling based on at least a torque command value, during constant torque acceleration or deceleration, and obtaining a maximum speed limit automatically. CONSTITUTION:An induction motor controller comprises a traveling torque estimating section 8, a maximum speed operating section 9 for determining a speed command limit value based on thus estimated traveling torque, and a limiter 10. When the speed is accelerated from n0 to n1, it is not accelerated directly from n0 to n1 but but an interval having slow acceleration gradient is provided and a torque command value tau* at that time is employed as a traveling torque. When estimating operation takes place in the traveling torque estimating section 8, the maximum speed operating section 9 determines an allowable rotational speed command value through a predetermined operation based on an estimated value or with reference to a predetermined table. The limiter 10 limits the rotational speed command so that the output from a speed setter 1 does not exceeds the output from the maximum speed operating section 9.

Abstract: PURPOSE:To dynamically change a data width in correspondence to the bus width of a larger device by arranging data in correspondence to the bus width and executing a change to cause a bus width signal from the device and the data width to be coincident when they are decident. CONSTITUTION:A prescribed parameter is set to a DMAC4 and an instruction to store 8 bit-data is outputted from an I/O circuit 3 to a buffer 51. Then, a 32 bit-width is set to a register 54. A buffer full-control 56 shows an OP0 and the first data are stored to the buffer 51 and next, the data are stored to OP1-OP3 in correspondence to the transferring request of the circuit 3. During the operation, the control 56 executes comparison between the values of the data arranging width register 54 and a buffer counter 55 and a buffle signal is sent to a DMAC4. When the transferring proceeds, the DMAC4 tries to transfer 32 bit-data from an address X to a memory and a memory 2 receives only the data of two bits. Then, the bus width signal is sent. The DMAC4 renews the address only by +2 and the data of 16 bits are transferred from the buffer 51 to the memory 2.
