Abstract
A motor drive control deviceincludes a drive voltage generation circuitconfigured to generate a drive voltage Vin based on a first supply voltage Vdc inputted to a first terminal Pand generate the drive voltage Vin based on a second supply voltage inputted to a second terminal Pwhen a supply of the first supply voltage Vdc is stopped, a control circuitconfigured to be operable by the drive voltage Vin, generate a drive control signal Sd based on a drive command signal Sc, generate a motor driving information signal So and output the motor driving information signal So from a third terminal Pand a motor drive circuitconfigured to output a drive signal to the motor, in which the control circuitmonitors the first supply voltage Vdc and outputs history informationrelating to operation of the motorfrom the third terminal Pas the motor driving information signal So upon detecting that the supply of the first supply voltage Vdc is stopped.
