State display device of industrial machinery and power conversion device
First Claim
1. A state display device of industrial machinery, comprising:
- an inputter configured to input a display control signal according to a state relating to the industrial machinery; and
a plurality of displays configured to display in a lighting state corresponding to a state of the industrial machinery, on the basis of the display control signal input by the inputter,wherein the plurality of displays is positioned in an approximately annular shape, the plurality of displays comprises two displays forming a half ring at one side of the approximately annular shape and one display forming a half ring at the other side of the approximately annular shape, the industrial machinery is a power conversion device that converts an external supply power into a drive control power to an electric motor, and the plurality of displays is configured to display in a lighting state corresponding to at least one of a rotation drive state of the electric motor, a drive standby state after the electric motor is turned on, and an abnormality generation or an abnormality prediction state of the electric motor.

Abstract
An LED indicator 4 connected to industrial machinery including an inverter 1, includes: an LED substrate 8 into which a display control signal according to a state relating to the industrial machinery is input; and a plurality of displays 31, 32, and 33 configured to display in a lighting state corresponding to a state of the industrial machinery, on the basis of the display control signal input by the LED substrate 8. The plurality of displays 31, 32, and 33 each include a partially circular-arc shape, and are generally arranged in an approximately annular shape. The plurality of displays 31, 32, and 33 include the two displays 31, 32 that generally configure a half ring at one side of the approximately annular shape, and the one display 33 that generally configures a half ring at the other side of the approximately annular shape.
