Applicable Industries

Installation Requirements

1. Flatness tolerance of mounting base surface ≤ 0.05 mm per 100 mm length
2. Radial runout misalignment between motor shaft and load coupling ≤ 0.02 mm
3. Minimum 50 mm unobstructed air circulation gap reserved around cooling fins
4. S40 cable static bending radius ≥ 8 times cable outer diameter, sharp right-angle bending prohibited
5. Connect motor housing PE grounding terminal with 4 mm² copper dedicated grounding wire

Operation Precautions

1. Strictly prohibit long-term continuous operation exceeding the 4500 RPM mechanical overspeed limit
2. Avoid direct impact radial load applied to the motor output smooth shaft
3. Operating environment relative humidity controlled at 5%–95% RH, internal condensation forbidden
4. Installation location must avoid conductive metal dust, acid and alkaline corrosive gas accumulation
5. Cut off the main power supply of the matched servo drive before disassembling the S40 hybrid connector to prevent feedback circuit burnout
