Core Functions
- Precision Control: Utilizes a 20-bit incremental encoder (1,280,000 pulses per revolution) to achieve ultra-fine positioning and stable low-speed rotation.
- Safety Holding (Electromagnetic Brake): The "S4" model suffix indicates it is equipped with a built-in electromagnetic brake. This function is critical for holding vertical loads (Z-axis) securely in place when power is removed, preventing accidental drops.
- Rapid Dynamic Response: As a "Low Inertia" motor, it offers a high velocity response frequency (up to 1 kHz) and a settling time below 1 ms, enabling fast start-stop cycles.
- Industrial Durability: Features an IP65 protection rating, ensuring it is dust-tight and resistant to water jets and oil mist common in machining environments. [, 2, 3, 4, 5]
