• Durability enhanced by 69% through frame and center of gravity optimization.
• Integration with HARMO auxiliaries via Datalink Integration System enables centralized control and monitoring.
• Quick-change EOAT adapters significantly reduce tooling changeover time.

5. Model Notation and Selection Guidance

• Model codes indicate arm type and axis configuration: S (3-Axis Single Arm), G (5-Axis Single Arm), SW (3-Axis Telescopic Arm), GW (5-Axis Telescopic Arm).
• Two 2-axis servo wrist rotation types: Ry (Ry & Rx axes) and Rz (Rz & Rx axes).
• Selection depends on production requirements such as parts release patterns and automation integration.

6. Dimensional Data and Mechanical Parameters

Comprehensive dimensional tables specify arm lengths, stroke ranges, home positions, reach limits, and mounting hole details essential for installation and integration planning.

7. Power and Air Consumption

• All models operate on 3-phase AC 200V ±10%, 50/60 Hz.
• Power consumption ranges from 1700 W to 2400 W depending on model.
• Working air pressure standardized at 0.5 MPa; air consumption varies slightly with vacuum ejector usage.

8. Pneumatic Circuit Parameters and Vacuum Ejector Consumption

• Parameters such as minimum and maximum pressure (P), flow (Q), and other pneumatic variables (R, S, T, Z) define operational limits.
• Vacuum ejector usage adds an additional air consumption of 46 L/min (ANR) per circuit, critical for air supply design.
• Optional components are indicated and should be evaluated for their impact on system performance.
• Component labels (A-Z) correspond to valves, sensors, or connection points within the pneumatic circuit.

Critical Information Summary

• Payload capacity ranges from 7 kg to 12 kg depending on model and EOAT complexity.
• Vertical and kick stroke dimensions are customizable with optional extensions.
• Wrist rotation types (Ry and Rz) provide flexibility for diverse automation tasks.
• Smart Programming and advanced controller features reduce programming time and enhance efficiency.
• Integration with HARMO auxiliaries and quick-change EOAT adapters improve productivity and minimize downtime.
