Servo controller for linear motor, has compensator connected to feeder line between power device and position return device and performing signal correction of position return device

摘要

The controller (20) has a position return device (30) and a power device (40), where the position return device moves against a linear motor (10). The power device is electrically connected to the linear motor and the position return device. A position compensator (60) is connected to a feeder line between the power device and the position return device, and performs signal correction of the position return device. The compensator has an input port, two counters, a converter, a pulse generator and an output port.
