PROBLEM TO BE SOLVED: To provide a motor controller that transmits and receives a synchronization signal for correcting a deviation of a clock between multiple microcomputers each operating with an independent clock and is capable of determining an abnormal synchronization signal.SOLUTION: A synchronization signal generation unit 411 of a transmission-side microcomputer 401 synchronizes with a driving timing of its own microcomputer, generates a synchronization signal for synchronizing the driving timing of the microcomputers 401 and 402, and transmits the signal to a reception-side microcomputer 402. A timing correction unit 422 of the reception-side microcomputer 402 can correct the driving timing of its own microcomputer so as to synchronize with the synchronization signal received, and includes a timing determination unit 432 that determines whether the received synchronization signal is normal or abnormal. The reception-side microcomputer 402 permits timing correction when it is determined in the timing determination that the synchronization signal is normal and prohibits timing correction when it is determined that the synchronization signal is abnormal, and drives a motor 80 asynchronously with the transmission-side microcomputer 401.SELECTED DRAWING: Figure 7
【課題】それぞれ独立したクロックで動作する複数のマイコン間で、クロックのずれを補正するための同期信号を送受信するモータ制御装置において、同期信号の異常を判定可能なモータ制御装置を提供する。【解決手段】送信側マイコン401の同期信号生成部411は、自マイコンの駆動タイミングに同期し、且つ、マイコン401、402の駆動タイミングを同期させる同期信号を生成し、受信側マイコン402に送信する。受信側マイコン402のタイミング補正部422は、受信した同期信号に同期するように自マイコンの駆動タイミングを補正可能であり、且つ、受信した同期信号の正常又は異常を判定するタイミング判定部432を含む。受信側マイコン402は、タイミング判定において同期信号が正常と判定されたとき、タイミング補正を許可し、異常と判定されたとき、タイミング補正を禁止し、送信側マイコン401とは非同期でモータ80を駆動する。【選択図】図7
