Summary: | PROBLEM TO BE SOLVED: To improve position accuracy of movable components with respect to operations of an external device.SOLUTION: A motor control device 6, which controls a drive of a rotary motor 2, includes: a timer 23 that counts timer setting time T0; a timer time setting unit 22 that sets the timer setting time T0; and a trigger output unit 24 that outputs a trigger signal, determining a timing when the counting of the timer setting time T0 by the timer 23 ends as an output timing. The timer time setting unit 22 is configured to set time (T0=(P-Pn-ΔP)/Vn) necessary for the rotary motor 2 of an output velocity Vn to output by a motor difference position (P-Pn-ΔP) having a motor output position Pn at a prescribed detection timing n and a prescribed delay position deviation ΔP subtracted from a photographing reference position P to the timer 23 as the timer setting time T0.SELECTED DRAWING: Figure 2
【課題】外部装置の動作に対する可動部品の位置精度を向上する。【解決手段】回転モータ2の駆動を制御するモータ制御装置6であって、タイマ設定時間T0を計時するタイマ23と、タイマ設定時間T0を設定するタイマ時間設定部22と、タイマ23によるタイマ設定時間T0の計時が終了したタイミングを出力タイミングとしてトリガ信号を出力するトリガ出力部24と、を有し、タイマ時間設定部22は、撮像基準位置Pから所定の検出タイミングnにおけるモータ出力位置Pnと所定の遅延位置偏差ΔPを差し引いたモータ差分位置(P−Pn−ΔP)だけ、出力速度Vnの回転モータ2が出力するのに要する時間(T0=(P−Pn−ΔP)/Vn)をタイマ設定時間T0としてタイマ23に設定する。【選択図】図2 |
