Title:
BRAKE DRIVING CONTROL CIRCUIT AND BREAKDOWN DETECTION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/116963
Kind Code:
A1
Abstract:
The purpose of the present invention is to not impair stability, to enable an application voltage to a high-side switch to be a relatively low voltage, and to negate the need for the provision of a separate large-capacity power circuit in a brake driving control circuit which controls an electromagnetic brake provided in a robot or the like. The brake driving control circuit, which controls an electronic brake that releases the brake by applying a current, is provided with: a first rectifying element provided between a first power supply of a first circuit voltage and one terminal of the electronic brake; a cut-off switch inserted into a line through which the first power supply supplies power; a first switching element provided between the other terminal of the electronic brake and a ground point; and a second switching element and a second rectifying element provided in series between a second power supply of a second circuit voltage, which is different from the first circuit voltage, and the one terminal of the electronic brake.
