II. Core Functional Features
1. High-Precision Motion Control
- Encoder Configuration:
The "DA" in the model likely corresponds to a high-precision magnetic encoder or absolute encoder (with a resolution of over 20 bits), supporting micron-level positioning accuracy. It is suitable for scenarios requiring trajectory interpolation (such as linear/circular interpolation), such as electronic component assembly and precision inspection equipment. - Control Loop Optimization:
Built-in advanced algorithms (such as adaptive filtering and feedforward control) can reduce tracking errors (position loop gain is adjustable) to ensure trajectory accuracy during high-speed motion.
2. High Dynamic Response Performance
- High Torque Density:
The LSA series features a compact design. Although the 35-frame is a small motor, it achieves high torque output through optimized magnetic circuit structures (e.g., rated torque of 3N·m, peak torque up to 9N·m). It is suitable for frequent start-stop or high-speed direction-changing operations (such as sorting actions in packaging machinery). - Fast Current Loop Response:
With a high current loop bandwidth, it quickly tracks controller commands and reduces dynamic lag, making it suitable for response-sensitive scenarios such as robot joints and semiconductor wafer handling.
3. Flexible System Integration Capability
- Industrial Bus Compatibility:
Supports B&R’s core bus Ethernet POWERLINK and may also be compatible with third-party buses such as CANopen and Profinet (requires corresponding interface modules), facilitating multi-axis synchronous control or integration with PLCs and robot controllers. - Plug-and-Play Adaptation:
Deeply matched with B&R ACOPOS series drives, the drive software can automatically identify motor parameters (such as rated current and number of pole pairs), reducing debugging time.
4. Reliable Industrial-Grade Design
- Protection Level:
Standard IP65 protection (dustproof and water jet-proof), suitable for industrial environments with dust and coolant splashes (such as machine tool processing areas). - Heat Dissipation and Durability:
The casing adopts a lightweight aluminum design with optimized surface heat dissipation ribs, supporting natural or forced air cooling and enabling continuous full-load operation (such as 24-hour production lines). The motor bearings use long-life lubricating grease with a design life of over 20,000 hours.
5. Abundant Protection and Diagnosis Functions
- Electrical Protection:
Built-in overload protection (current limiting), overheat protection (monitored by temperature sensors), and overvoltage/undervoltage protection to prevent motor damage from abnormal conditions. - Fault Diagnosis:
Real-time monitoring of motor status (such as torque, temperature, and encoder signal quality) via the drive or host computer software, supporting fault code recording and traceability for quick problem troubleshooting.
III. Typical Application Scenarios
1. Small Automation Equipment
- Such as collaborative robot joints (requiring low inertia and high response), automatic labeling machines (high-speed positioning and synchronous motion), and semiconductor die bonders (sub-micron precision requirements).
2. Precision Machining Fields
- Feed shaft drives for small CNC machine tools (such as benchtop milling machines and engraving machines), or electronic component plug-in machines (high-speed picking and precise positioning).
3. Packaging and Logistics Industry
- Servo pusher shafts in pharmaceutical/food packaging lines (fast start-stop and position control), and AGV car drives (requiring compact installation and high reliability).

---|---|---|
Precision | Supports absolute encoders with higher resolution (e.g., 23 bits) | High-resolution encoders need to be optionally configured for some models |
Dynamic Response | Higher current loop bandwidth (e.g., 5kHz), faster acceleration | Conventional bandwidth of 2-3kHz, suitable for medium-speed scenarios |
System Integration | Deeply 协同 with B&R automation platforms (e.g., Automation Studio) | Requires third-party protocol conversion, higher integration complexity |
Protection Level | Standard IP65, adapts to harsher environments | Protection needs to be customized for some competitors |

V. Usage Precautions
Installation Requirements:
- Ensure coaxiality between the motor shaft and load (error ≤0.02mm) to avoid abnormal bearing wear.
- Encoder cables must use shielded wires and be routed separately from power cables to reduce electromagnetic interference.
Parameter Debugging:
- Perform automatic motor identification (such as back EMF and inductance measurement) via the drive during initial use to ensure control loop parameter matching.
- If the load inertia is large, increase the speed loop integral time (I value) to avoid oscillation.
Environmental Adaptability:
- Operating temperature range: 0°C~60°C (requires good ventilation), storage temperature: -20°C~80°C.
- Avoid use in strong electromagnetic interference environments (such as near frequency converters and welding machines); add filters if necessary.
