STD3722M

3 -Phase Digital Hybird Stepper Driver

Features

1. 3-phase digital stepper driver, adoption of 32-bit DSPtechnology

2. Low-noise, low-vibration and low temperature rising

3. Voltage 110v-220VAC

4. With 8 stalls output current setting, peak current 7.0A

5. With 16 stalls microstep subdivision setting, the highest resolution of 60000 steps / turn

6. Automatic half current, self-test, over voltage, under voltage, over current protection

7. Internal optical isolation, the highest response frequency of up to 200Kpps

8. Suitable for nem42, nema52 3-phase Hybird stepper motor between1.2-7.0A

9. When the step pulse stops for more than 100ms, the coil current is automatically reduced to half of the set

current, effectively reducing the motor heat

10. Signal voltage : 5V ~ 24V compatible

11. Working temperature: -30 ℃ ℃ ~ 85  ℃

Note:

D5: ON, double pulse: PU is forward step pulse signal, DR is reverse step pulse signal

OFF, single pulse: PU is the step pulse signal, DR is the direction control signal

D6: automatic detection switch (OFF when receiving external pulse, ON the drive to the internal speed of 30 r /

min)
