Product Overview

The Kollmorgen SERVOSTAR 310 is a high-performance digital servo amplifier belonging to the S300 servo drive family, also known by its part number S31061-NA. This compact 70mm-wide servo drive delivers precise closed-loop motion control for single-axis automation equipment. It is the highest power rating model within the 110~230V AC class of the SERVOSTAR 300 series, widely used for machine upgrade, spare parts replacement and legacy production line maintenance.

SERVOSTAR 310 supports position, velocity and torque control modes. Built-in motion controller can store up to 300 positioning tasks, supporting electronic gearing and cam profiles for packaging machinery, cutting equipment, material handling, printing and automated assembly systems. It is a discontinued original Kollmorgen drive, popular for aftermarket industrial spare parts supply.
