Servo motor position control device |
| abstract |
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). |
