STD27H-A220E Sewing Machine Tray Controller

STD27H-A220E is a tray controller for sewing machines, which is based on a two-phase digital stepper driver with a feedback port to capture the actual rotation position of the motor, ensure that the stepper motor does not lose step, does not lose step, greatly improves the accuracy and reliability of the stepper motor.

  • Using vector control and micro-subdivision control technology, it has greatly improved the running stability, noise, vibration and heat generation compared with traditional drives       
  • Strong and weak electrical isolation, strong anti-interference ability, good stability
  • Adaptive control of attenuation mode and attenuation time, the switch tube runs in the minimum switching mode, the heat generation is greatly reduced during operation, and the distortion of the current waveform is small (the current waveform above 8r/s is still maintained as a sine wave)   
  • It has 16 levels of constant torque subdivision at equal angles, and the maximum resolution is 60,000 steps/rpm
  • The maximum response frequency can reach 200Kpps
  • Acceleration and deceleration curve configuration of the maximum motor no-load speed up to 50R/S (or 3000RPM)
  • When the step pulse stops for more than 100ms, the coil current is automatically reduced to 20%-80%
  • Photoelectric isolated signal input/output
  • The drive current is adjustable from 0.3A/phase to 6A/phase
  • Single power input, voltage range: DC DC24-50/80V± within 15%.
  • Error protection: no motor detection, overtemperature protection, overcurrent protection, internal anomaly protection
  • Phase memory function (Note: After the input pulse stops, the actuator automatically remembers the motor phase at the time, and the driver automatically restores the motor phase when the power-up is restarted or the MF signal changes from active to invalid).
