Product Details:

KOLLMORGEN S72402-NANANA-NA-225 is a single-axis digital servo amplifier of the SERVOSTAR 700 series. NANANA represents the base hardware configuration, NA means no optional fieldbus interface card, and the suffix 225 stands for the specific firmware and hardware variant. It supports three-phase 230-480VAC power input, 24A continuous output current and 48A peak current, equipped with high-bandwidth digital control loop, delivering strong torque output, rapid dynamic response and excellent synchronous stability for medium-heavy load motion axes. It is widely matched with Kollmorgen AKM and Goldline servo motors, applied on CNC machine tools, printing presses, heavy packaging lines and rotary positioning platforms, supporting torque, speed and built-in position control modes. Users can install bus expansion cards later for CANopen, PROFIBUS and other bus communication when multi-axis synchronization is required.

This servo amplifier supports resolver, incremental encoder, sine/cosine encoder, EnDat, BiSS and HIPERFACE feedback signals to form complete closed-loop motion control. It adopts cabinet-mounted compact structure, power terminals and feedback connectors are separated to suppress electromagnetic interference in oil mist and dusty workshop environments. It integrates STO safe torque off function to comply with industrial safety standards. Built-in regenerative braking circuit realizes energy recycling during deceleration, and external brake resistor can be configured for heavy deceleration applications. The front panel is fitted with LED status indicators and fault code display for convenient on-site inspection and fast fault diagnosis. High-speed digital control loop ensures smooth acceleration and deceleration and stable positioning precision under long-cycle continuous operation.

Professional technicians can tune speed loop gain, position loop gain, current limiting value and motion profile parameters through Kollmorgen WorkBench configuration software according to different load characteristics. Multiple built-in monitoring circuits keep real-time track of DC bus voltage, output current and internal temperature. Once overload, overheating, overvoltage, undervoltage or feedback signal loss is detected, the drive will rapidly disable output and trigger alarm signal to avoid mechanical collision and servo motor burnout. The robust housing has good vibration resistance and adapts to long-time continuous operation in industrial workshop conditions.

This KOLLMORGEN S72402-NANANA-NA-225 servo amplifier has been discontinued by the original manufacturer. It is supplied as a tested aftermarket replacement spare part for legacy automation equipment. Maintenance personnel can complete replacement safely after power cut, and the original wiring and mechanical installation dimensions can be retained without large modification.

It is a high-capacity SERVOSTAR 700 series special variant drive spare part, frequently selected for maintenance and upgrade of old high-performance multi-axis motion control systems.
