Pin Definition
| Pin No. | Name | Description |
|---|---|---|
| 1 | VDC | Supply voltage: 12-50VDC |
| 2 | GND | Supply Voltage Ground: GND/0V |
| 3 | PUL | Pulse Control Signal Input: Rising Edge effective. PUL high level: 4~5V, Low level: 0~0.5V. Make sure pulse signal effective, pulse width ≥ 1.2μs. Add the resistance for power supply. |
| 4 | PUL- | |
| 5 | DIR | Direction Signal: high/low level signal, pulse width > 5μs. High level: 4~5V, Low level: 0~0.5V. |
| 6 | DIR- | |
| 7 | ENA | Enable Signal: enable/disable. If ENA connect 5V & ENA- connect low level (or Internal optocoupler on), stepper controller will turn off the current, motor in free state, no feedback even send pulses. |
| 8 | ENA- | |
| 9 | TXD | To the TX pin on user device (not for communication, set parameter only) |
| 10 | RXD | To the RX pin on user device (not for communication, set parameter only) |
