PECIFICATIONS
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.
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 network 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) net-
work 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.
Three different IP ratings are available in the SMD23E2 and SMD24E2 product lines.
IP50: Units have sealed M12 D-coded connectors for their ethernet ports. A sealed M12 A-coded con-
nector is used for power and two digital inputs.
IP64: Units have a shaft seal and sealed M12 D-coded connectors for their ethernet ports. A sealed
M12 A-coded connector is used for power and two digital inputs.
IP65/67: Units have a shaft seal and sealed M12 D-coded connectors for their ethernet ports. A sealed
M12 A-coded connector is used for power and two digital inputs. Additionally, the units are
sealed with an FDA approved epoxy.
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
