An AH500 series motion control module performs operations on three types of values according to
various control purposes. The functions of the three types of values are described below.
1.
Binary number (BIN)
The values on which an AH500 series motion control module performs operations, and the
values stored in the AH500 series motion control module are binary numbers. Binary
numbers are described below.
Bit: A bit is the basic unit of information in the binary system. Its state
is either 1 or 0.
Nibble: A nibble is composed of four consecutive bits (e.g. b3~b0).
Nibbles can be used to represent 0~9 in the decimal system, or
0~F in the hexadecimal system.
Byte: A byte is composed of two consecutive nibbles (i.e. 8 bits,
b7~b0). Bytes can be used to represent 00~FF in the
hexadecimal system.
