8. Installation Instructions
- Mounting SurfaceInstall on a rigid, flat, and vibration-free base to avoid resonance and mechanical stress.
- Shaft AlignmentAlign motor shaft and load shaft precisely to prevent excessive vibration, noise, and bearing damage.
- CablingUse shielded servo power cables and encoder cables. Separate power and signal wiring to minimize electromagnetic interference. For the brake, use a dedicated DC24V power line.
- Heat DissipationMaintain clear space around the motor housing for natural convection; do not cover cooling surfaces.
- HandlingAvoid heavy impact, dropping, or compression on the motor body and encoder cover.
9. Maintenance
- Regular InspectionCheck for unusual noise, vibration, or overheating during operation. Test the brake function periodically.
- CleaningKeep motor surface free of dust, metal chips, and oil.
- BearingsSealed bearings are pre-lubricated for life; no routine greasing required.
- Encoder & CablesInspect encoder cables and connectors periodically for damage or looseness. Check brake wiring for wear.
- Operation LimitsAvoid continuous overload and excessive frequent start–stop cycles. Do not use the brake for dynamic stopping.
10. Safety Precautions
- Electrical SafetyDisconnect all power before wiring or maintenance. Wait at least 15 minutes for capacitor discharge to prevent electric shock. The brake must be powered off when not in use.
- Moving PartsDo not touch rotating shaft or moving components during operation.
- Brake SafetyThis model is equipped with a holding brake. The brake is for holding only, not for dynamic braking. Ensure the brake is energized (released) during operation and de-energized (engaged) when stopped or power is cut off.
- Do Not DisassembleUnauthorized disassembly of motor, brake, or encoder will void warranty and may damage precision components.
- Environmental ProtectionDo not use in environments with conductive dust, heavy condensation, or chemical corrosion without proper protection.
11. Troubleshooting
- Motor does not startCheck 3-phase power, wiring connections, amplifier alarms, servo enable signals, and brake release signal.
- Abnormal noise or vibrationCheck mounting rigidity, shaft alignment, bearing condition, mechanical load jamming, and brake drag.
- Motor overheatingCheck for overload, high ambient temperature, blocked ventilation, insulation deterioration, or brake not fully released.
- Positioning errorCheck encoder cable damage, loose connectors, parameter mismatch, mechanical backlash, or brake slipping.
- Unstable speedCheck power supply fluctuation, sudden load changes, encoder signal interference, or brake drag.
- Brake failureCheck DC24V brake power supply, wiring, coil resistance, and mechanical friction.
