Document Type and Number:
Japanese Patent JP6536319
Kind Code:
B2
Abstract:
A robot system includes a motor, an inverter, a first control portion, and a second control portion. The motor includes stator windings for three phases. The inverter includes series-connection bodies of a high-side switch and a low-side switch for three phases. A connection point of the high-side switch and the low-side switch for each of the phases is connected with the corresponding stator winding. One of the high-side switch and the low-side switch for each of the phases works as a brake switch. The first control portion and the second control portion performs a driving control of the brake switches. Each of the first control portion and the second control portion has a function of monitoring the robot system, and turns on the brake switches for at least two phases when detecting that an abnormality occurs in the robot system.
