| Blink Code | Error Text | Immediate Action | | :--- | :--- | :--- | | 2 Red / 1 Green | (Overcurrent at start) | Check for mechanical jam or short in motor phases. Measure resistance between U-V-W: should be 2.5–3.5Ω. | | 4 Red / 1 Green | E.SEn (Sensor error) | Replace encoder battery (CR2032) or clean optical disk. V11 requires >2.7V. | | Steady Red | E.OVt (Overtemperature) | Reduce duty cycle below 85% or enlarge heatsink (min 150x150x10mm). | | Flashing Orange | E.CPU (V11 watchdog timeout) | Reload firmware via bootloader (push SW1 while powering on). |

| Parameter | Value / Range | Notes | | :--- | :--- | :--- | | | 300 W (0.4 HP) | Ideal for small-to-medium load applications | | Rated Torque | 0.95 – 1.2 Nm | Continuous operation without cooling | | Peak Torque | 3.5 – 4.0 Nm | For acceleration/emergency stops (≤2 sec) | | Rated Speed | 3000 – 5000 RPM | Standard for industrial servo | | Input Voltage | 200 – 240 VAC (single/three phase) | Or 48 VDC for low-voltage variants | | Feedback Type | 17-bit absolute encoder (131072 ppr) | Digital "D302" implies high resolution | | Protection Class | IP54 (dust-protected, water splashes) | Higher IP65 available as option | | Ambient Temp | 0°C to 40°C (32°F to 104°F) | Derating above 1000m altitude | | Weight | Approx. 1.5 – 2.0 kg | Compact footprint for tight machinery |

In the rapidly evolving landscape of industrial automation and precision machinery, model numbers like BLMachV11 D302 often represent the cutting edge of engineering. While not a household consumer name, this specific alphanumeric code is critical for OEMs (Original Equipment Manufacturers), maintenance technicians, and system integrators in the servo motion control sector.
