About ECMA-F11845RS Delta Servo Motor 4500W H , Torque Nm - 28.65 , RPM - 1500
Control & Motion Intelligence
- Control Modes: Position, Speed, and Torque (switchable via I/O or communication).
- Feedback Resolution: Supports 20-bit incremental encoders (1,280,000 pulses/rev) and 17-bit absolute encoders.
- Electronic Cam (E-CAM): Built-in logic with up to 720 points for master-slave synchronization.
- Specialized "U" Features: Supports high-speed digital command execution and includes an extension port for additional digital inputs.
Suppression & Safety
- Vibration Suppression: Dual low-frequency vibration filters to eliminate mechanical shaking in large-scale machinery.
- Resonance Suppression: Features advanced high-frequency auto-notch filters.
- Safety Function: Built-in Safe Torque Off (STO), ensuring hardware-level power cut-off for operator safety (SIL2/PL d).

Function & Performance
- Extreme Torque: Delivers a massive rated torque of 28.65 Nm and a peak instantaneous torque of 71.62 Nm, making it the "powerhouse" for large-scale industrial presses, heavy gantry systems, and large CNC machines.
- High Inertia Stability: Specifically functional for controlling extremely heavy mechanical loads. The high rotor inertia provides superior resistance to external disturbances and ensures ultra-smooth motion under heavy stress.
- Precision: Features the standard 20-bit incremental encoder (1,280,000 pulses/rev) for high-resolution positioning despite its massive size.
- Industrial Build: Rated IP65 with a built-in oil seal, ensuring reliability in harsh factory environments where heavy oils and dust are present.
