モータ制御システム
Document Type and Number:
Japanese Patent JP7452026
Kind Code:
B2
Abstract:
To control an inverter circuit even when at least one of a motor current sensor and a voltage sensor has an abnormality.SOLUTION: A motor control system 10 includes an inverter circuit 11, an inverter control unit 121 that controls operation of the inverter circuit, a motor current acquisition unit 122 that acquires a current value detected by a motor current sensor 13, an input voltage acquisition unit 123 that acquires the value of an input voltage to the inverter circuit detected by a voltage sensor 14, and an abnormality information acquisition unit 127 that acquires abnormality information indicating occurrence of an abnormality in at least one of the motor current sensor and the voltage sensor. When the abnormality information acquisition unit acquires abnormality information, a control value that is usable for control of the inverter circuit is acquired from a device separated from the motor control system, and the acquired control value is used to control the inverter circuit.SELECTED DRAWING: Figure 3
