ツク検出装置。 A set value generating means for inputting a current limit value and outputting a set value corresponding to the input, a reference time generating means for inputting a current limit value and outputting a reference time signal corresponding to the input, and a current command value or current detection value of the motor. and a setting value from the setting value generating means, and outputting an out-of-setting-range detection signal if the current command value or current detection value is outside the range of the setting value, and the reference time. Lock determining means inputs the reference time signal from the generating means and the out-of-setting-range detection signal from the out-of-setting-range detection means, and outputs a lock detection signal when the out-of-setting-range detection signal continues for a reference time or longer. A motor lock detection device characterized by:
