DRIVING DEVICE FOR PULSE MOTOR

摘要

PURPOSE:To control the pulse motor at high speed and smoothly by overlapping and using the data of a memory storage in response to the change of the number of moving steps and computing and obtaining control characteristics. CONSTITUTION:The pattern data memory storage ROM1 memorizes switch control data. An arithmetic device ALU1 receives switch control signals, and calculates the number of the moving steps. An arithmetic device ALU2 conducts the setting of an initial address and the initial setting of the reading order and reading number of a pulse time data memory storage ROM2 on the basis of the output of the arithmetic device ALU1. An arithmetic device ALU3 counts the number of steps in each mode, and an arithmetic device ALU4 computes an address of the memory storage ROM2. An arithmetic device ALU5 receives the output of the arithmetic device ALU3, and changes the modes with the decrease of the number of moving steps coupled with the functioning of a loop counter RC, and the inclination is eased.
