摘要： A remote maintenance system 1 is provided with a linear motor apparatus 2, a motor driver 3 for controlling a motor of the linear motion apparatus 2, and a user terminal 4. The motor driver 3 includes a memory which stores parameters relating to motor control. The user terminal 4 acquires the parameters from the motor driver 3, and sends the parameters to a maintenance server 5. Then, the user terminal 4 receives the parameters adjusted by the maintenance servers from the maintenance server 5, and writes the parameter into the memory of the motor driver 3. Thus, the parameters of the linear motion apparatus can be adjusted from remote locations at a high precision.

摘要： A control unit of a motor driver performs feedback control to supply current to a linear motor based on a detection value of a linear encoder. An anomaly detection unit monitors the supply current to the linear motor, and the anomaly detection unit detects anomaly of a linear motion apparatus based on a waveform of the supply current. In the case where the anomaly is detected, a user is notified of warning by means of a lamp, a buzzer, an e-mail, and the like. Therefore, the anomaly of the linear motion apparatus can be detected early and accurately.

摘要： Provided is a technique to suppress hunting in a range of a minimum resolution of a pulse encoder when a servo motor has reached a target position and stopped, thereby maintaining a stable stop state. A servo motor position control device uses a cascade configuration having a position control loop as a main loop and a velocity and current control loop as a minor loop. A proportion control is performed for a position control while a proportion integration control is performed for a velocity control and a current control. When the servo motor position has reached the target position and stopped (S201), a current instruction value for the current control is maintained at a value upon stop (S202) and the current control is switched to the proportion control (S204).
