5. Wiring & Commissioning Guidelines

5.1 Pinout Definition

Terminal Type Pin Label Function Description
Power Input V+ / V- DC power supply positive/negative
Control Signal PUL+/PUL- Pulse input (differential signal)
Control Signal DIR+/DIR- Direction input (differential signal)
Encoder Feedback A+/A-; B+/B-; Z+/Z- Encoder phase A/B/Z differential signals
Motor Output U1/U2; V1/V2 Motor phase winding connections

5.2 Wiring Precautions

- Route encoder cables separately from power cables to avoid electromagnetic interference.
- Use shielded cables for control and encoder signals; ground the shield at one end only.
- Confirm voltage and polarity before powering on to prevent component damage.

5.3 Commissioning Steps

1. Wiring Check:Verify all connections match the pinout definition; ensure no short circuits.
2. Parameter Configuration:Use the host computer software to set microstepping and output current (≤ motor rated current).
3. No-Load Test:Power on, verify rotation direction and speed stability; optimize acceleration/deceleration curves.
4. Load Test:Apply load gradually, monitor temperature rise and vibration levels; adjust parameters as needed.
5. Alarm Troubleshooting:If an alarm occurs, power off immediately, check wiring and parameter settings before restarting.



6. Selection & Matching Notes

1. Ensure motor rated current ≤ driver continuous output current for long-term stable operation.
2. Select a power supply with output power ≥ 1.5 × motor rated power to accommodate peak load demands.
3. Match the driver’s pulse frequency range to the equipment’s required operating speed.
