特徴とする電動機駆動装置のシーケンス回路。The switch placed on the AC power supply side of the motor drive power converter is opened and closed by the output of the operation relay connected to the DC operation power supply via the switch of the protection relay, thereby protecting the motor drive power converter. In the sequence circuit of the motor drive device, a semiconductor switch is provided in series with the excitation coil of the operation relay, and the semiconductor switch is driven through an abnormal signal generator that makes the semiconductor switch conductive in a normal state or makes the semiconductor switch non-conductive when an abnormal open command is input. A sequence circuit for an electric motor drive device, characterized in that:
