1. Model Definitions and Configurations

• Model Codes: Include outlet mode (End outlet 'D', Side outlet 'C'), electromagnetic brake options (with or without brake), series type (HP Series), version codes (T or S), reduction ratios (T series 45:1, S series 68:1), supply voltage (AC 220V), and servo encoder configurations (multi-turn absolute encoder with Tamagawa protocol, 23 bits single-turn, 16 bits multi-turn).
• Encoder: Absolute encoder with single-turn resolution of 23 bits and multi-turn resolution of 16 bits.

2. Performance Parameters

Parameters are provided for various HP series models (HPG-20S, HPG-20T, HPG-30S, HPG-40S, HPG-40T, HPG-50S), including:

• Peak torque and rated torque (e.g., 3 N·m peak for HPG-20S, up to 55 N·m for larger models).
• Maximum and rated speeds (rpm).
• Maximum and rated currents (Arms).
• Motor constants such as torque constant (N·m/Arms), resistance (Ohms at 20°C), inductance (mH), and back EMF constant (Vrms/krpm).
• Encoder resolution and positioning accuracy: single-turn resolution up to 23 bits, multi-turn 16 bits, with angular positioning accuracy typically in the range of 15-35 arcseconds and repeatability within a few arcseconds.
• Stiffness parameters: torsional stiffness (N·m/Arcmin), tilting stiffness (N·m/Arcmin).
• Load capacities: rated and instantaneous radial and axial loads (N).
• Mass and rotor inertia values.

3. Environmental and Operational Conditions

• Operating temperature range: 0 to 40°C.
• Storage temperature range: -20 to 60°C.
• Humidity: 20-80% RH, non-condensing.
• Vibration resistance: 24.5 m/s² (frequency 10-400 Hz).
• Protection rating: Standard IP65 (fully enclosed, self-cooling), optional IP67 available.
• Insulation resistance: ≥100 MΩ at DC 500V.
• Insulation withstand voltage: AC 1500V for 1 minute.
• Insulation class: F.
• Usage environment: Indoor use, no dust, metal powder, corrosive or flammable gases, or fog; avoid direct sunlight; altitude below 1000m.

4. Mechanical Accuracy

• Parallelism, coaxiality, and runout tolerances for output shafts and mounting surfaces are specified, typically within 0.01 to 0.05 mm depending on the parameter and series.
• Special requirements for end face and radial runout can be accommodated upon request.

5. Load and Moment Allowable Values

Allowable bending moments, radial forces, and axial forces are specified for different series:

• HAS/HAT/HAM/HAG Series: Bending moment allowable values range from 36 N·m to 2500 N·m; instantaneous bending moments up to 5000 N·m; radial forces up to 3200 N (continuous) and 6500 N (instantaneous); axial forces up to 3200 N continuous and 6500 N instantaneous.
• HPG-S Series: Bending moments up to 1886 N·m continuous and 3583 N·m instantaneous; radial forces up to 10000 N continuous and 23000 N instantaneous; axial forces up to 6000 N continuous and 11400 N instantaneous.
• HPG-T Series: Bending moments and axial forces specified in kN and N·m, e.g., bending moments up to 3470 N·m and axial forces up to 20 kN depending on model.

6. Service Life and Accuracy Retention

• HAS/HAT/HAM/HAG series have an accuracy retention life of approximately 15,000 hours under rated load and 30 rpm operation.
• HPG series have an extended accuracy retention life of approximately 20,000 hours under similar conditions.
• Note: Service life values assume positioning accuracy and other parameters remain constant; life can be extended if slight parameter degradation is acceptable.

7. Additional Notes and Recommendations

• Models are available with or without electromagnetic brakes.
• Outlet modes (side or end) affect installation and wiring options.
• Frameless torque motors and planetary gearboxes are integrated for high rigidity and precision.
• Users should avoid environments with dust, metal powders, corrosive or flammable gases, and direct sunlight to maintain performance and longevity.
• For special mechanical accuracy requirements, contact the manufacturer’s sales team.
