Abstract

A brake control system includes: a plurality of motors each provided with a brake device and a position detecting section; and a brake control device that controls a plurality of the brake devices using one brake-oriented power source. The position detecting section includes a position detecting circuit section and a communication circuit section. The brake device includes: a current detecting section that detects a brake current flowing through a brake coil of an electromagnetic brake; and an insulating circuit section that electrically insulates the current detecting section and the communication circuit section. The communication circuit section transmits to the brake control device the brake current acquired via the insulating circuit section. The brake control device includes a fault specifying section that specifies the faulty brake device based on a plurality of detection signals detected by a plurality of the current detecting sections.
