The STM24x-3 integrated stepper is a drive+motor unit, fusing a NEMA 24 step motor and a sophisticated 6.0 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 popwer supplies.
The STM24C-3Cx integrated stepper is designed to operate on a CANopen communication network and conforms to Can in Automation (CiA)
DS301 and DSP402 specifications. It supports Profile Position, Profile Velocity, and Homing modes, as well as the ability to run stored Q programs
via Applied Motion-specific CANopen objects.
The STM24SF-2Ax integrated stepper can operate in the following control modes: step (pulse) & direction, velocity (oscillator), streaming serial
commands . (STM24 integrated steppers do not support stored-program operation with the Applied Motion 4-axis and 8-axis SiNet Hubs).
The STM24QF-3x integrated stepper can operate in all of the same control modes as the SF option, plus the ability to run a Q program stored
in non-volatile memory. Q programs are created using Applied Motion’s Q Programmer™ software, which provides powerful commands for
motion, I/O, conditional processing, multi-tasking, math functions, and more. All STM23 units are setup and configured using Applied Motion’s
ST Configurator™ software.

On units ordered with and encoder. 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 STM24x-3xE 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 STM24 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 STM24x-3Ax comes with an RS-232 port for programming and serial communications. The STM24x-3Rx comes with an RS-485 port for
programming and serial communications.
