Composition of Absolute Data
Absolute data consists of singe-turn data which shows the absolute position per one
revolution and multi-turn data which counts the number of revolution of the motor after
clearing the encoder.
Single-turn data and multi-turn data are composed by using 15-character data (hexadeci-
mal binary code) which are received via RS232 or RS485.
