Summary:To provide a motor controller with a fault detection function and a monitoring function of a dynamic brake circuit.SOLUTION: A motor controller comprises: a motor 1; an inverter circuit 2 which drives the motor 1; first wiring L1 which connects the motor 1 with the inverter circuit 2; second wiring L2 which connects the motor 1 with the inverter circuit 2; a first sensor S1 which detects first current flowing to the first wiring L1; a second sensor S2 which detects second current flowing to the second wiring L2; and a dynamic brake circuit 3. The dynamic brake circuit 3 is connected between the first sensor S1 and the motor 1, and between the second sensor S2 and the inverter circuit 2.SELECTED DRAWING: Figure 1 【課題】ダイナミックブレーキ回路の故障検出機能及びモニタリング機能を備えたモータ制御装置を提供する。【解決手段】モータ制御装置は、モータ1と、前記モータ1を駆動するインバータ回路2と、前記モータ1と前記インバータ回路2とを接続する第一配線L1と、前記モータ1と前記インバータ回路2とを接続する第二配線L2と、前記第一配線L1に流れる第一電流を検出する第一センサS1と、前記第二配線L2に流れる第二電流を検出する第二センサS2と、ダイナミックブレーキ回路3と、を備える。前記ダイナミックブレーキ回路3は、前記第一センサS1と前記モータ1の間と、前記第二センサS2と前記インバータ回路2の間に接続されている。【選択図】図1
