Abstract

A motor drive with an RF tag is provided. The motor drive according to an embodiment of the present invention, which is a motor drive for driving a motor, includes a detection circuit for detecting the state of the inside of the motor drive; a first memory and a second memory for storing information including a detection value indicating the state detected by the detection circuit; an RF tag having the first memory; an interface circuit for transmitting and receiving information to and from external equipment; and a controller for transmitting at least a part of the information stored in the second memory to the outside through the RF tag or the interface circuit.

Description

technical field [0001] The invention relates to a motor drive device, in particular to a motor drive device with an RF tag. Background technique [0002] Conventionally, there is known a motor drive device having an RF (Radio Frequency: radio frequency) tag inside the device (for example, JP-A-2006-174614. Hereinafter referred to as "Patent Document 1"). An RF tag is an electronic device that can transmit information in an internal memory to an external device by wireless communication without requiring power supply from a motor drive device. [0003] In Patent Document 1, there is described a motor drive device having a function of sending the management information (alarm) stored in the RF tag to the information, etc., all information in the motor drive unit) to the external device. [0004] exist figure 1 The structure of the conventional inverter apparatus which drives and controls a motor is shown in . An RF tag (IC (Integrated Circuit) tag) 1002 is fixed to the inv...
