METHOD FOR CONTROLLING POSITIONAL INFORMATION OF ENCODER MOTOR

摘要

PURPOSE:To simplify the constitution of a system and to obtain motor position information to be used for motor control by allowing an upper rank computer to fetch a counted value of output of an encoder of motor computer. CONSTITUTION:A motor microcomputer MPU1 is connected to an upper microcomputer MMPU1 through an interface circuit INF1 and a two-way data bus DB1. An encoder E is coupled with a DC motor M and a counted value COUNT counted by an up/down counter UDCNT is monitored by the computer MPU1. Monitored positional information is stored in a storage circuit in the computer MPU1 and the stored position signal is transferred in accordance with a request from the computer MMPU1. In said system constitution, the computer MMPU1 inputs the counted value COUNT to find the motor position information used for motor control.
