The LS series low-voltage servo drives represent a new generation of high-performance, high-precision, and high-reliability products developed by Hollysys Motor Technology Co., Ltd. in response to market demands. With standard operating voltage ranging from 24 to 70VDC, these drives offer compact size, superior stability, and convenient networking capabilities. Supporting multiple control methods including CAN, Modbus bus, pulse, and analog signals, they are widely applied in logistics and warehousing systems, handling systems, sorting systems, and medical equipment where voltage and space constraints are critical.

For users in specialized industries such as low-temperature environments, communications, and installation, the company offers customized low-voltage servo drives, including single-axis, dual-axis integrated, four-axis integrated, low-temperature, and high-shielding protection models. These variants facilitate seamless integration with equipment, making them ideal for AGVs, logistics systems, explosion-proof equipment, and temperature testing devices.

Autonomous Parking Function:

Utilizing bus interaction and dynamic braking principles, the autonomous parking system ensures synchronized emergency stops. When one drive reports an error or fault, it notifies other drives to simultaneously enter dynamic braking mode, forcing motors to stop rapidly for synchronized operation.

Power-Saving Design:

To extend AGV standby duration, the drives incorporate energy-efficient modes to minimize power consumption.

Lifting Without Limit Switches:

Based on automatic overload reduction technology, the drive detects position limits without external switches, enabling precise control of AGV lifting mechanisms.

Voltage Compensation:

During power voltage fluctuations, the drive's current loop parameters remain unaffected, ensuring consistent performance and stability.

Braking Functionality:

Equipped with electromagnetic braking, dynamic braking, and regenerative braking capabilities, the drives ensure safe operation during shutdowns. The built-in brake power supply directly controls power-failure brakes.

In recent years, the company has launched multiple standardized low-voltage servo system series, widely applied in mobile robots, warehousing logistics, postal sorting, CNC equipment, medical devices, power inspection, special equipment, and entertainment industries.
