Overview; Characteristics - Delta AS Series Operation Manual

1.2 Overview

An AS series CPU module is an advanced controller with built-in 6 high speed counters for inputs, up to 6-axis
(pulse), and can optionally work with a total of 8-axis (CANopen) position outputs. It provides a strong network
function for users, and users can create connection among devices on the network through software. An AS
series CPU module also provides structured programming. Users can assign programs to different tasks, and
write a program which is frequently executed in a function block. Besides, users can choose different
programming languages ladder diagrams (LD), structured texts (ST), sequential function charts (SFC), and
continuous function chart (CFC) dealt with by IEC 61131-3 according to their needs when writing programs.
They can create the AS series hardware configuration by means of hardware configuration software. They can
also restore or back up a system rapidly through the built-in SD interface in an AS series series CPU module.
This manual introduces the basic operation of an AS series system, and help users familiarize themselves with
the AS series system.

1.3 Characteristics

Characteristics of the AS series CPU module:
(1) High efficiency
 The AS Series CPU module uses a 32-bit high-speed processor. The module executes basic
instructions at 25 ns each and moving instructions at 150ns each. The module executes instructions
at a speed of 40k steps/ms (40% of the instructions are basic instructions, and 60% of the instructions
are applied instructions).
 The CPU of the AS Series uses the Soc architecture, built with six (or 3) high speed counters. The
maximum frequency is 200 kHz for each counter (differential output models can reach 4 MHz);
six-axis high speed position output at 200 kHz (differential output models can reach 4 MHz).
(2) Supporting more inputs and outputs
 The AS series CPU module supports up to 1024 digital I/Os or 32 I/O modules (any type) or 16 analog
I/O modules.
 The AS series works with SCM/DNETcommunication modules (AS-FCOPM, and AS-FEN02 included)
to create a remote connection, and you can connect up to 15 remote modules.
Note: For the connections between the CPU modules and the remote modules, the I/O points cannot
exceed 1024 I/Os, 32 I/O modules (any type), or 16 analog I/O modules.
(3) Multiple I/O modules
 The AS series CPU module supports the following I/O modules: digital input/output modules, analog
