Elevator inverter system, elevator inverter abnormality determination method, server, and mobile terminal

摘要

The elevator inverter system 1 includes a motor control circuit 210 that supplies electric power to the motor 100 in order to control the motor 100 that raises and lowers the car 14 of the elevator 2, and an inverter inside when the elevator 2 operates under predetermined operating conditions. Normal waveform storage unit 251 for storing normal waveform information representing the operation waveform of the motor, and motor control when the operating elevator 2 operates under a predetermined operation condition based on the normal waveform information stored in the normal waveform storage unit 251 An abnormality determination unit 244 that determines whether the motor control circuit 210 is operating normally by comparing operating waveform information representing an operation waveform in the circuit 210 with normal waveform information.
