Description

CB10250 Kollmorgen SERVOSTAR CD Series Digital Servo Drive

Overview

As a flagship member of the SERVOSTAR CD platform, the CB10250 utilizes a high-performance DSP to execute fully digital current, velocity, and position loops with sinusoidal commutation, ensuring ultra-smooth, low-ripple motion and precise positioning. It supports incremental encoders, resolvers, sine encoders, and Hall-effect sensors, plus auxiliary encoder feedback for dual-loop or master-slave configurations. The drive features a rugged, space-saving panel-mount design with an IP20-rated enclosure, built to withstand vibration, thermal stress, and harsh industrial environments.
