STM23S-xxx Integrated Drive+Motor

The STM23S-2AN, STM23S-2RN, STM23S-3AN, and STM23S-3RN 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. This integrated stepper can operate in the following control modes: step (pulse) & direction, velocity (oscillator), streaming serial commands (SCL), and operation with an Applied Motion 4-axis or 8-axis SiNet Hub. All STM23 units are setup and configured using Applied Motion’s ST Configurator™ software.


Each STM23 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 STM23S-2AN and STM23S-3AN comes with an RS-232 port for programming and serial communications. The STM23S-2RN and STM23S-3RN comes with an RS-485 port for programming and serial communications.


Features include:

  • Sophisticated current control
  • Anti-resonance
  • Torque ripple smoothing
  • Microstep emulation
  • Step & direction, CW/CCW pulse, and A/B quadrature control modes
  • Oscillator (velocity) control mode
