________________________________________________________________________________________

he Absolute Encoder Interface Board is an Inner Board that allows position data to be directly input from absolute rotary encoders.

Absolute High-speed Counter

The Absolute Encoder Interface Board reads binary gray codes (inverted binary codes) input from an absolute encoder at a maximum counting rate of 4 kHz, and can perform interrupt processing according to the input values.

Interrupts

An interrupt subroutine can be executed when the PV (present value) of the absolute high-speed counter matches a specified target value (target value comparison) or falls within a specified comparison range (range comparison.)

Note: When an absolute encoder is used the position data can be re-
tained even during power interrupts, so it isn’t necessary to per-
form an origin return when power is returned. In addition, the origin
compensation function allows the user to specify any position as
the origin.
