ERROR JUDGMENT VALUE SETTING METHOD, MOTOR CONTROL DEVICE, AND ACTUATOR

摘要

A control unit of a motor driver automatically operates a linear motion device according to a given drive condition. An error judgment value setting unit samples the peak of the current supplied to the linear motor during the automatic operation. According to the peak value sampled, an error judgment value used for detecting an error of the linear motion device is set. For example, the error judgment value can be set at the peak value multiplied by about 1.2 to 1.4 and more preferably, by 1.25 to 1.3. Thus, it is possible to automatically set an error judgment value in accordance with the drive condition of the linear motion device.
