CONTROLLER AND POWER CONVERTER

摘要

PROBLEM TO BE SOLVED: To provide a controller which allows a user to quickly and easily perform an operation using key input loaded on a power converter.SOLUTION: A controller includes: an operation part for performing the operation of increasing or reducing parameter data to be set; a display part for displaying the parameter data; a processing part for processing an operation instruction from the operation part; and a storage part for storing change of the parameter data from the processing part. The processing part automatically stops the change when the data parameter reaches a suitable value in the case that the operation command from the operation part is continuously inputted, and continues the change again when the operation command from the operation part is continuously inputted even when the fixed time elapses thereafter.
