<P>PROBLEM TO BE SOLVED: To provide a motor drive controller capable of normally drive-controlling an inverter. <P>SOLUTION: The motor drive controller 1 includes a converter 3, an inverter 4, a converter micro-computer 8 and an inverter micro-computer 7. The converter 3 converts power supply current Im to direct current. The inverter 4 is supplied with the direct current from the converter 3 and supplies drive voltages SU, SV, SW to a motor 51. The converter micro-computer 8 drive-controls the converter 3 and monitors the power supply current Im. The inverter micro-computer 7 drive-controls the inverter 4 and outputs an operation allowing signal SC to the converter micro-computer 8. The converter micro-computer 8 obtains the operation allowing signal SC indicating that the inverter 4 is in a drive stop condition, and when the power supply current Im is a predetermined value A or higher, the converter micro-computer resets the inverter micro-computer 7. <P>COPYRIGHT: (C)2010,JPO&INPIT |
