The
STM23IP-2EE integrated stepper is a drive+motor unit, fusing a NEMA 23
step motor and a sophisticated 5.0 A/phase (peak-of-sine) stepper drive
into a single device. Power to the drive, located at the rear of the
motor, must be supplied by an external DC supply. See Related and
Recommended Products below for compatible 24 and 48 volt DC
power supplies.
The STM23IP-2EE integrated stepper incorporates EtherNet/IP network
communications, the widely used industrial protocol for manufacturing
automation applications. With EtherNet/IP users can control, configure
and query the drive using an open, standards-based, industrial Ethernet
connection at speeds up to 100 MBits/sec. All STM23IP units run the same
control modes as STM23Q units, with the addition that all drive+motor
features can be accessed over EtherNet/IP, including more than 100
commands and 130 registers for controlling motion, I/O, configuration,
polling, math, register manipulation, and Q programming. Setup and
confiugration of the STM23IP is done using Applied Motion’s
ST Configurator™ software, while Q programs are created using the Q Programmer™ software.
An integral 1000-line (4000 count/rev) incremental encoder is housed
inside the same enclosure as the drive electronics, providing protection
from dust and debris. The integration of the encoder means the STM23IP
can perform special functions not available otherwise. Stall Detection
notifies the system as soon as the required torque is too great for the
motor, which results in a loss of synchronization between the rotor and
stator, also known as stalling. Stall Prevention actually prevents
stalling of the step motor by dynamically adjusting motor speed to
maintain synchronization of the rotor to the stator under all
conditions. This unique feature allows step motors to operate in a much
broader range of applications than previously available to step motors,
such as torque-control applications. The Stall Prevention feature also
performs static position maintenance, which maintains the position of
the motor shaft when at rest.
Each STM23IP integrated stepper comes with 3 digital inputs, 1
digital output, and 1 analog input. The digital inputs accept signals
of 5-24 VDC and can be used for connecting pulse & direction
signals, end-of-travel limit switches, jog switches, quadrature encoder
signals, PLC outputs, sensors, or many other signal types. The digital
output can be connected to PLC inputs, counters, lights, relays, or
other devices. The analog input accepts 0-5 VDC signals and can be used
for velocity and position control.
The STM23IP-2EE comes with a fast 10/100 MBit Ethernet port for
programming and EtherNet/IP communications. The same port also supports
TCP and UDP protocols for sending commands from Applied Motion’s
proprietary serial command language (SCL).
All STM23IP models are CE approved and RoHS compliant.
