The SMD23E2 and SMD24E2 Families
The SMD23E2 and SMD24E2 units are part of a
growing product line from AMCI with a simple con-
cept: a stepper indexer, driver, and motor that can be
attached to any popular industrial network. Each
SMD23E2 or SMD24E2 attaches to your Ethernet
network and communicates using the EtherNet/IP,
Modbus TCP, or PROFINET protocols.
The SMD23E2 and SMD24E2 units are members of
the growing line of products from AMCI that incor-
porate our
E2 Technology . E2 Technology by AMCI
is an innovative new multi-protocol approach to
Ethernet distributed I/O.
E2 Technology products are simple and intuitive,
allowing easy transition between multiple common
industrial Ethernet protocols without the need to
physically switch parts. An advanced web server
integrated into all AMCI E2 Technology devices
facilitates simple device configuration and trouble-
shooting via web-browser. Furthermore, an impressive array of advanced features for each supported protocol
has been incorporated into the devices to meet many unique application requirements.
Each unit has two Ethernet ports which are internally connected through an onboard, two port, 10/100 Mbps
ethernet switch. These ports allow you to wire your network in a “daisy-chain” fashion, which may lower net-
work wiring costs and complexities.
The two ports also allow the units to function as members of a redundant Device Level Ring (DLR) network
when using the EtherNet/IP protocol or as clients in a Media Redundancy Protocol (MRP) network when
using PROFINET.
In DLR environments, the SMD23E2 and SMD24E2 units act as Beacon-Based Ring Nodes. All units can
process beacon packets at the default rate of every 400 microseconds. Beacon-based nodes can respond faster
to network changes than nodes that only process Announce packets.
Each unit can be ordered with an optional incremental or absolute multi-turn encoder. This encoder gives you
the additional functionality of position verification and stall detection. The absolute multi-turn encoder allows
you to track machine position with power removed, eliminating the need to home the machine after cycling
power.
This manual is designed to get you up and running quickly with an SMD23E2 or
SMD24E2 product from AMCI. As such, it assumes you have some basic knowl-
edge of stepper systems, such as the resolution you want run your motor at, and
the reasons why you’d want to use Idle Current Reduction and the reasons why
you wouldn’t. If these terms or ideas are new to you, we’re here to help. AMCI has
a great deal of information on our website and we are adding more all the time. If
you can’t find what you’re looking for at http://www.amci.com, send us an e-mail
