STD35S-A220 three-phase closed-loop digital stepper driver

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: AC110~ 220V± within 15%.
Error protection: no motor detection, overtemperature protection, overcurrent protection, internal anomaly protection
Phase memory function (Note: After the input pulse stops, the driver automatically remembers the motor phase at that time, and when the power-on is restarted or the MF signal changes from active to invalid, the driver automatically restores the motor phase).
