STM Series NEMA 24 frame Integrated Motor/Drives - Integrated Stepper Motors
from $379.00/ea

STM integrated steppers are drive+motor units, fusing step motor and drive components into a single device. This space-saving design eliminates wiring and saves on cost over conventional motor and drive solutions.

The STM24 integrated steppers combine high torque NEMA 24 step motors with a sophisticated, 6.0 A/phase (peak-of-sine) step motor drive. Power to the drive, located at the rear of the motor, must be supplied by an external DC supply. Applied Motion offers compatible 24 and 48 volt DC power supplies for exactly this purpose.

Control Options:

The STM24 integrated steppers come with the choice of three control options: S, Q, and C.

  • The 'S' control option means the drive can operate in the following control modes: step (pulse) & direction, velocity (oscillator), and streaming serial commands (SCL). (STM24 integrated steppers do not support operation with the Applied Motion 4-axis and 8-axis SiNet Hubs).
  • The 'Q' control option means the drive can operate in all of the same control modes as the S 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.
  • The 'C' control option means the drive is designed to operate on a CANopen communication network and conforms to Can in Automation (CiA) DS301 and DSP402 specifications. C drives support Profile Position, Profile Velocity, and Homing modes, as well as the ability to run stored Q programs via Applied Motion-specific CANopen objects.

All STM24 integrated steppers, whether they come with the S, Q, or C control option, are setup and configured using Applied Motion’s ST Configurator™ software.

Encoder Option:

Optional 1000-line (4000 count/rev) incremental encoders are available for STM24 steppers. The encoder is housed inside the same enclosure as the drive electronics, providing protection from dust and debris. The addition of the encoder means the stepper 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. 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.

Inputs/Outputs:

The STM24SF and STM24QF model numbers come with 4 digital I/O points, called Flex I/O points, because each point can be individually defined as an input or an output. As inputs, the Flex I/O points 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. When defined as digital outputs, the Flex I/O points can be connected to PLC inputs, counters, lights, relays, or other devices.

The STM24C model numbers come with 3 digital inputs and 1 digital output. The digital inputs accept signals of 5-24 VDC and can be used for connecting 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.

All STM24 model numbers come with 1 analog input. The analog input accepts 0-5 VDC signals and can be used for velocity and position control.

Communication Ports:

STM24 integrated steppers with the S and Q control options are available with either RS-232 or RS-485 ports for programming and serial communications. For single-axis applications where no serial networking is required the RS-232 option is recommended. For applications where communications over a serial network are required the RS-485 option is recommended. Units with the C control option come with an RS-232 port for programming and a CANopen port for network communications.
