PURPOSE:To reduce in size an inverter by assigning a plurality of inverter functions to be switched in a software to operation keys, and varying the blink digit and speed of a number displaying light emitting diode in response to the operation mode of the inverter. CONSTITUTION:The function settings of inverters are switched in a software, and operations of various modes are formed by operation keys 2. Blink digit and speed of 3-digit 7-segment LED 1 are varied in response to the mode. Three numbers are displayed without flashing in an operation mode. In an operating program mode, 10<2> digit number is blinked and the blink speed is fast. In a stop mode, 10<2>-10<0> digit numbers are blinked and the blink speed is slow. In a stopping program mode, 10<2> digit number is blinked and the blink speed is slow. Alphabet and number are displayed without blink in a strip mode. |
