<P>PROBLEM TO BE SOLVED: To provide a fan motor control arrangement capable of precisely controlling the current value of a fan motor without affected by the error caused by variation in characteristics of the fan motor itself. <P>SOLUTION: When a correction value storing command signal is received through a receiving means 10a of a high voltage part 1a, the specific fan motor current whose value is known is supplied to a fan motor FM from a known current supply means 9. If the correction value storing command signal is received through the receiving means 10b of a low voltage part 1b, a control means 2 compares an AD input value from a current detecting means 6 to a logical output voltage stored in an EEPROM8 to acquire a correction data which is stored in the EEPROM8. The control means 2 controls the fan motor FM based on the calibrated voltage data acquired by taking the correction data into account. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
