Claims

[Scope of utility model registration request]

(1) In a motor variable speed inverter that performs variable speed control by controlling the power supply voltage supplied to the motor, there is an A/D converter that converts analog setting input of frequency or rotation speed into digital, and this A/D converter. outputs a digital signal for controlling the motor based on a digital setting input from the motor, and also displays digital display data for displaying information regarding the rotation speed of the motor and an abnormal state when an abnormal input is supplied. a digital processing circuit for creating digital display data for the digital processing circuit; a digital display for predetermined digits for displaying the digital display data from the digital processing circuit; and a digital display for driving the digital display by the output from the digital processing circuit. 1. A display device for a motor variable speed inverter, comprising: a drive circuit; the setting input is normally displayed digitally; and an abnormality is displayed when an abnormality occurs.

(2) The digital processing circuit creates a plurality of abnormality display data in response to a plurality of abnormal inputs, and the contents of the abnormality are classified and displayed on the digital display. A display device for a motor variable speed inverter according to scope 1.
