SYNCHRONOUS AC SERVO DRIVING CONTROLLER

摘要

PURPOSE: To reduce wiring manhours and to improve reliability by using a synchronous motor for controlling the shaft of a servo controller and setting the magnetic pole position signal of an encoder detecting the angle of a rotor and a signal detecting the relative amount of the rotor to be common wiring lines. ;CONSTITUTION: A switching circuit in the encoder selects U/W phase signals only at the time of detecting a magnetic pole position when power is supplied, and A/B/Z phase signals are selected for subsequent selection. Thus, the wiring lines can be shared.;COPYRIGHT: (C)1994,JPO&Japio
