Product Details:

KOLLMORGEN S72402-NANANA-NA is a single-axis digital servo amplifier belonging to the SERVOSTAR 700 series. The suffix NANANA-NA defines its specific configuration of feedback, I/O and interface options, NA means no optional fieldbus card installed. It supports 230-480VAC three-phase power supply, with 24A continuous output current and 48A peak current, equipped with high-bandwidth digital control loop, providing powerful torque output, fast dynamic response and high synchronous stability for medium and heavy-load motion axes. It is widely used in CNC machine tools, printing machinery, packaging production lines and automated rotary positioning platforms, supporting torque, speed and built-in position control modes. Users can add communication expansion cards later to connect mainstream industrial bus for multi-axis synchronous control.

This servo amplifier supports resolver, incremental encoder, sine/cosine encoder, EnDat, BiSS and HIPERFACE feedback signals, forming complete closed-loop motion control system with Kollmorgen AKM and Goldline series servo motors. It adopts standard cabinet-mounted structure, power terminals and feedback connectors are separated to reduce electromagnetic interference in dusty and oil mist workshop environments. It integrates STO safe torque off function to meet industrial safety requirements, and built-in regenerative braking circuit for energy recovery during deceleration, supporting external brake resistor expansion for heavy deceleration conditions. The front panel has LED status indicators and fault code display for convenient on-site inspection and quick troubleshooting. High-speed control loop ensures smooth acceleration and deceleration and stable running precision under long-cycle continuous operation.

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

This KOLLMORGEN S72402-NANANA-NA 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 general-purpose drive spare part, frequently selected for maintenance and upgrade of old high-performance multi-axis motion control systems.
