| Driver Current | 0.3~0.95A/phase (up to 2.0A/phase) |
|---|---|
| Input Voltage | DC 24V ~ 36V (minimum 1.6A) |
| Stepping Mode | Full‑step (1.8°/step) or Half‑step (0.9°/step, selectable) |
| Protection Functions | Reverse‑polarity and over‑current protection |
| Dimensions | 90 mm (L) × 65 mm (W) × 32 mm (H) |
| Weight | 177 g |
| Operating Temperature | 0 °C ~ 40 °C |
Use the RUN switch to set the current; the adjustment range is 0.3 A/phase to 2 A/phase, with the factory default at 1.32 A/phase.
When the H.OFF signal is low (L level), the motor current stops and the holding torque is released, allowing the shaft to be turned by hand.
Use the H/F switch: the H side selects half‑step operation (0.9°/step), while the F side selects full‑step operation (1.8°/step).
Connect the positive supply to the DC24V/36V terminal (I) and the negative supply to the COM terminal as shown in the wiring diagram.
