Kolmosen SR10201-000000 Servo Drive Detailed Product Description

I. Product Overview

SR10201-000000 is a 10A class, 480V class fully digital servo drive from the ServoStar SR series of Kolmosen. It is designed for 4.5–5.5kW medium-large power, high-torque output traditional servo systems. The model suffix -000000 represents the basic configuration version with no additional features: pure analog command, dual feedback interface, built-in regenerative braking, standard basic I/O, no fieldbus, no STO safety function. The core difference lies in the voltage specification - SR10201 is a three-phase 480V high-voltage version (different from SR10200's 230V), suitable for high-voltage, high-power servo motors, and widely used in traditional industrial automation scenarios such as heavy machinery, large packaging machines, material handling, textile machinery, etc.
