DISPLACEMENT DETECTOR FOR AN ENCODER |
摘要 |
In construction of a displacement detector for an encoder provided with a phase locked loop connected to a detection head facing a scale of the encoder, use of a signal switching circuit allows optimum selection of signals used for generation of a system output signal depending on the speed of the relative movement between the detection head and the scale, thereby assuring generation of the system output signal at high degree of dissolution at any speed of the relative movement. Further, additional use of a parallel/serial converting unit assures high reliability in transmission of the system output signal to external systems. |
