III. Functional Features

1. Simplified Vector Control for Small Light-Load Scenarios

It adopts a simplified vector control algorithm optimized for small light-load scenarios, combined with a 12-bit high-precision current sampling module and a 16-bit high-performance processor, achieving cost optimization while ensuring control precision. In the control mode with an incremental encoder, the speed control precision reaches ±0.01% and the position control precision reaches ±0.01mm, meeting the needs of scenarios with basic precision requirements such as small packaging machinery and light-load sorting equipment. In the sensorless vector control mode, a speed control precision of ±0.3% can be achieved without an external encoder, making it suitable for light-load scenarios with low precision requirements such as ordinary small conveyor lines and micro fans. The V/F control mode is compatible with traditional small induction motors, enabling low-cost upgrade and transformation of old small equipment. It supports the zero-speed torque holding function, which can stably output 80% of the rated torque at zero speed, meeting basic process requirements such as small-scale clamping and light-load positioning. The speed step response time is ≤10ms and the torque step response time is ≤5ms, which can quickly adjust the output in load change scenarios common in small equipment (e.g., start/stop of conveyor lines, action switching of packaging mechanisms) to ensure operational stability.

2. Practical Interface Configuration for Convenient Small-System Integration

It adopts a practical interface design, equipped with miniaturized control interfaces and basic communication interfaces, enabling quick integration into various small automated systems. The control interfaces include 2-channel high-speed pulse input (maximum frequency 500kHz), 2-channel 12-bit analog input, and 6-channel photoelectrically isolated digital I/O. It supports mainstream control methods such as pulse control (position/speed), analog control (speed/torque), and digital control (start/stop/forward/reverse), and can be directly connected to the output interfaces of economical PLCs such as Mitsubishi FX1N and Siemens S7-200 SMART without additional adapter modules, significantly reducing integration costs and installation space occupation. The communication interface is standard with RS485 (supporting Modbus-RTU protocol), and an optional simplified PROFINET RT module is available to meet the basic data interaction needs of small systems. It supports the upper-level system to remotely read and modify servo parameters, improving the centralized management efficiency of small production lines. The USB debugging interface, combined with SEW simple debugging software, can quickly complete parameter configuration, program download, and basic fault diagnosis, simplifying the debugging process and adapting to the rapid production needs of small equipment manufacturers.

3. Basic Safety Protection for Stable and Reliable Operation

It builds a basic three-level protection system of "power supply - motor - drive", optimizing the protection logic according to the operating characteristics of small equipment to achieve core safety protection. The power supply side is equipped with overvoltage, undervoltage, phase loss, and overcurrent protection. When the input voltage is ≥600VAC or ≤320VAC, the drive immediately cuts off the output and triggers an alarm to avoid damage to small equipment caused by power grid abnormalities. The motor side is equipped with overcurrent, overload, locked-rotor, overspeed, and overtemperature protection. When the motor locked-rotor time exceeds 3s, the overload protection is triggered and the motor stops, while recording the fault type to facilitate quick troubleshooting. The drive itself adopts an efficient natural heat dissipation design: when the temperature of core components reaches ≥90℃, it automatically reduces the output power; when the temperature reaches ≥100℃, it shuts down for protection. It also has short-circuit and ground fault protection to fully ensure equipment safety. Equipped with a fault recording function that can store the latest 20 fault records, with an MTBF of up to 500,000 hours, it meets the reliability requirements of continuous operation of small equipment and reduces the frequency and cost of operation and maintenance.

4. Cost-Effective Design for Precise Cost Control

It adopts a full-process cost optimization design, significantly reducing equipment investment costs while ensuring core performance. At the hardware level, it uses highly integrated chips and a simplified module architecture to reduce the number of components and manufacturing costs. At the control algorithm level, it adopts simplified vector control technology to balance control precision and computing resource occupation, enabling basic precise control without a high-performance processor. At the interface configuration level, it focuses on the core needs of small equipment and omits redundant interfaces to reduce hardware costs. Meanwhile, the drive has a standby power consumption of ≤30W, saving 10%-15% more energy compared with similar traditional products. It is especially suitable for scenarios where small equipment is in standby for a long time or operates intermittently, and can significantly reduce energy consumption costs in long-term use. It supports adaptation with SEW economical CMP series motors to form a cost-effective drive kit, further reducing the overall procurement cost of small equipment and improving the market competitiveness of products.

5. Miniaturized & Convenient Operation and Maintenance for Reduced Management Costs

It adopts a miniaturized design, with a volume of only 150mm×200mm×100mm and a weight of approximately 2kg, supporting cabinet-mounted and wall-mounted installation, and adapting to the narrow installation space and compact layout of small equipment. Equipped with an HCS10 simple operation panel that supports Chinese display, it allows intuitive viewing of core operating parameters such as speed and current. Through the panel, control mode switching, basic parameter setting, and fault reset can be completed, enabling operation and maintenance personnel to perform basic operation and maintenance without professional debugging skills. It supports local firmware upgrading, and program updates can be completed via the USB interface to obtain performance optimization and extend the service life of the equipment. The SEW simple debugging software has built-in parameter configuration templates and fault diagnosis guidelines dedicated to small equipment, which can quickly complete parameter configuration and common fault troubleshooting, reducing the requirements for the professional level of operation and maintenance personnel and further lowering management costs.

6. Basic Environmental Adaptability for Small-Scenario Requirements

It adopts a basic anti-interference and environment-adaptive design, fully meeting the operating needs of small industrial scenarios and household automation upgrades. The power input side is equipped with a basic EMC filter, complying with the EN 61800-3 EMC basic level standard, which can effectively suppress common power grid interference and avoid interference to other electronic components of small equipment. The control signals adopt photoelectric isolation protection, and in ordinary industrial environments (e.g., small workshops, packaging workshops), the signal transmission error rate is ≤0.001%, ensuring stable transmission of control signals. It has a wide voltage input range (380-480VAC±10%), which can adapt to areas or small workshop scenarios with small power grid voltage fluctuations without additional voltage regulators. The operating temperature range supports 0℃-50℃, and the natural heat dissipation design does not require additional cooling equipment, adapting to the installation environment of small equipment without forced heat dissipation. The relative humidity is 10%-90% (non-condensing), and the protection class reaches IP20, meeting the basic protection needs of cabinet-mounted installation of small equipment.
