Claims

[Scope of utility model registration request]

Attach a digital position detector to the drive servo monitor,
In a side control device that controls a servo motor by inputting a position feedback pulse and a one-rotation pulse signal from the digital position detector to a control device, the position feedback pulse and one-rotation pulse are used to mutually detect erroneous pulses. What is claimed is: 1. A position detection device having a function of correcting the position feedback pulse and one rotation pulse based on a detected erroneous pulse.
