Product Details:

KOLLMORGEN S21260-SRS is a medium-high power single-axis digital servo amplifier belonging to the SERVOSTAR S200 series, SRS suffix stands for integrated SynqNet real-time motion bus interface. It supports 120/240VAC single-phase or three-phase AC power input, rated continuous current 12A and peak current 30A, built-in high-bandwidth current loop and velocity loop regulator, delivering excellent dynamic stiffness for medium and heavy load motion axes that demand high synchronous precision and fast response. It is widely deployed on semiconductor equipment, printing machinery, packaging lines and CNC feed axes, supporting torque, speed and built-in position control modes for multi-axis synchronous motion systems based on SynqNet network.

This servo amplifier adopts SFD Smart Feedback Device as the primary feedback, and supports expansion for sine/cosine encoder signals, forming closed-loop motion control with matched Kollmorgen AKM and Goldline series servo motors. It uses standard DIN rail cabinet mounting structure, power terminals and feedback connectors are separated to reduce electromagnetic interference in complex industrial electrical environments. Dual RJ45 SynqNet ports support daisy-chain wiring for multi-node bus connection. It integrates STO safe torque off function to satisfy industrial safety standards, and built-in regenerative braking circuit for energy recycling during deceleration, external brake resistor can be configured for heavy deceleration loads. Front panel LED indicators and fault code display simplify on-site fault diagnosis and maintenance.

Technicians can tune loop gain, current limit and motion profile parameters through Kollmorgen S200 configuration software according to different load characteristics. Multiple internal monitoring circuits continuously track 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 compact housing is sturdy and vibration-resistant, suitable for long-time continuous operation in factory workshop environments.

This KOLLMORGEN S21260-SRS servo amplifier has been discontinued by the original manufacturer. It is supplied as a tested aftermarket replacement spare part for legacy SynqNet multi-axis motion systems. Maintenance personnel can complete replacement safely after power cut, and the original SynqNet bus topology and wiring scheme can be retained without large modification.

It is a classic medium-high capacity S200 series SynqNet drive spare part, frequently selected for maintenance and upgrade of old high-performance synchronous automation equipment.
