Displacement data transmission apparatus used for transmission of e.g. position and velocity of machine, has output unit that outputs converted displacement data with respective cyclic code

摘要

The apparatus has displacement data converter (14) that includes displacement data conversion units for converting several sensor signals into identical displacement data in absence of irregularities. A cyclic code generator (11) generates cyclic code for the converted displacement data, and number of bits in first displacement data is equal to or greater than number of bits in second displacement data. An output unit (12) outputs the converted displacement data with respective cyclic code.
