CONTROL BOARD COOLING SYSTEM, CONTROL BOARD COOLING METHOD AND PROGRAM COOLING CONTROL BOARD

摘要

PROBLEM TO BE SOLVED: To provide a control board cooling system capable of initiating the cooling of the control board in an area where irrespective of temperature rises.;SOLUTION: A CPU 31 first monitors (s11) the control state of a main shaft 10, and starts the operation of a cooling fan 40 (s13) when the control state reaches a first control state accompanied by a temperature rise in a control board 1 (s12: YES). Next, the CPU monitors the control state of the main shaft 10, and stops the operation of the cooling fan 40 after the elapse of a predetermined time when the control state reaches a second control state not accompanied by a temperature rise in the board 1 (S15: YES).;COPYRIGHT: (C)2003,JPO
