8. Installation Instructions

1. Mount motor strictly at B5 flange; avoid mechanical impact on shaft.

2. Align coupling or gearbox precisely to prevent radial/axial overloading.

3. Use shielded power cable and encoder cable, EMC grounding required.

4. Keep ventilation area clear; do not cover motor housing.

5. Check cable bending radius to avoid long-term fatigue damage.

• Motor power connector: 3-phase U/V/W + PE

• Brake connector: 24 V DC positive / negative

• Encoder connector: EnDat signal, power and shield

10. Safety Instructions

• Disconnect power before wiring or maintenance.

• Wait until motor and drive fully discharged before touching terminals.

• Do not run motor without load test for long time.

• Do not disassemble encoder or brake structure privately.

• Ensure reliable protective earth connection.

11. Maintenance

• Regularly check cable tightness and insulation aging.

• Check motor running noise and temperature rise.

• Verify brake holding performance periodically.

• Keep motor surface clean and dust-free.

12. Common Troubleshooting

• Motor no rotation: Check power wiring, brake release signal, enable signal.

• Overspeed / position deviation: Check encoder cable and EnDat communication.

• Overheat alarm: Check load overload, ventilation blocked or bearing wear.

• Brake not release: Check 24 V brake voltage and wiring.
