を特徴とするモータ制御装置。[Claims for Utility Model Registration] A two-phase encoder feedback type motor control device includes a polarity determination circuit 10 that determines the polarity of the current speed command value, and a phase detection circuit that detects the phase of input A phase/B phase. If the circuit 20 and the polarity determining circuit 10 determine that the phases of A phase/B phase are opposite, an abnormal signal is output and the positional relationship of A/B phases is reversed. A motor control device characterized by having a malfunction prevention circuit 30.
