General Functionality

Each member of the SMD23E2 and SMD24E2 families has three integrated parts:

An indexer that accepts commands over an Ethernet connection using the EtherNet/IP, PROFINET, or
Modbus TCP protocols

A 3.4 Arms micro-stepping driver that accepts 24 to 48 Vdc as its input power source

A high torque size 23 or size 24 stepper motor (130, 240, or 350 oz-in holding torque).
An incremental or absolute multi-turn encoder is also available for applications that require position feedback
or verification.
The availability of the EtherNet/IP, PROFINET, and Modbus TCP protocols makes the SMD23E2 and
SMD24E2 units easy to integrate into a wide variety of control systems. This combination of host and driver
gives you several advantages:

Sophisticated I/O processing can be performed in the host (PLC or other controller) before sending
commands to the SMD23E2 or SMD24E2 unit
 All motion logic is programmed in the host, eliminating the need to learn a separate motion control 
language

The integral two port Ethernet switch simplifies network cabling

The DLR interface eliminates single point failures in EtherNet/IP environments

The MRP interface eliminates single point failures in redundant PROFINET environments

The elimination of the separate indexer and driver lowers total system cost.
An SMD23E2 or SMD24E2 is powered by a nominal 24 to 48 Vdc power source, and can accept surge 
voltages of up to 60 Vdc without damage. The output motor current is fully programmable from 1.0 Arms to
3.4 Arms which makes the SMD23E2 and SMD24E2 units suitable to a wide range of applications. In addi-
tion to the Motor Current setting, the Motor Steps per Turn, Idle Current Reduction, and Anti-Resonance Cir-
cuit features are also fully programmable. If you have used other stepper indexer products from AMCI, you
will find programming an SMD23E2 or SMD24E2 to be very similar to these products.
The SMD23E2 and SMD24E2 contains a true RMS motor current control driver. This means that you will
always receive the motor's rated torque regardless of the Motor Steps/Turn setting. (Drivers that control the
peak current to the motor experience a 30% decrease in motor torque when microstepping a motor.) The
combination of an ultra-low inductance motor and a high-power, true RMS driver gives unprecedented torque
vs. speed performance for any DC application.
