Document Type and Number:
WIPO Patent Application WO/2019/240168
Kind Code:
A1
Abstract:
[Problem] The purpose of the present invention is to provide a brake circuit discharge system that can quickly and reliably stop a power source. [Solution] A brake circuit discharge system 100 of the present invention comprises: a motor drive circuit 101 that drives a motor M; a brake drive circuit 102 that drives a brake B for decelerating and stopping driving of the motor M, and applies the brake during power interruption; a control unit 103 that controls the operation of the motor drive circuit 101 and the brake drive circuit 102; a capacitor 106 that is connected to a power line of the brake drive circuit 102; a discharge resistor 108 that is connected in parallel with the capacitor 106 to the power line of the brake drive circuit 102; a discharge switching switch 109 that is serially connected to the discharge resistor 108; and a discharge command generation circuit 110 that is connected to the discharge switching switch 109, and that generates switching command signals for opening and closing the discharge switching switch 109.
