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.
