Absolute Encoder Interface Board Section 8-3
Precautions when
Selecting an Absolute
Encoder
One of the following three kinds of Absolute Encoders must be used in order
to take advantage of all of the Absolute Interface Board’s functions without
restrictions.
8 bit (256 resolution) gray binary
10 bit (1,024 resolution) gray binary
12 bit (4,096 resolution) gray binary
The resolution of the encoder that is being used with the Absolute Encoder
Board must be set in the PC Setup (bits 00 to 07 of DM 6643 or DM 6644) as
shown below.
8-bit resolution: 00
10-bit resolution: 01
12-bit resolution: 02
When an 8-bit encoder is used in 360
° Mode, the 256 resolution is converted
to 360
° Mode, so the values are converted as shown in the following table.
(The upper row shows the input value from the Encoder and the lower row
shows the output value after conversion to degrees.)
