- Single-axis, dual-in-one with multiple options Single-axis RMS current up to 100A Supports CAN bus interface with built-in standard CANopen Supports multi-turn absolute encoders Mass-proven in AGV, AMR, and other industries
The RS Series low-voltage servo system is a new generation high-performance, high-reliability product developed by HollySys Motor Technology Co., Ltd. in response to market demands. The RS Series drivers operate on low-voltage DC power supply, utilize digital signal processing chips (DSP) as the core control unit, and feature high-speed data processing capabilities. They employ advanced full-digital motor control algorithms to precisely control the position, speed, and torque of permanent magnet synchronous low-voltage servo motors. Supporting multiple control methods including CAN, Modbus bus, pulse, and analog signals, the system is widely applied in mobile equipment fields such as service robots, inspection robots, and logistics AGVs.
Technical Advantages
BROTHER Partner Monitoring
The BROTHER partner monitoring system utilizes bus object synchronized listening functionality. When a driver reports an error or fault, it notifies other drivers via the CAN bus and immediately enters shutdown mode to ensure safe, synchronized, and rapid stopping.

Enhanced CAN Bus Transmission Algorithm
Comprehensive and reliable CAN bus data processing ensures zero packet loss
Multi-Power Device Parallel Technology

The RS Series drivers have been successfully mass-deployed in logistics automation, factory material handling robots, and multiple other industries.
