CB06250 Kollmorgen SERVOSTAR CD Series Digital Servo Drive

The CB06250 is a high‑performance, compact digital servo drive from Kollmorgen’s SERVOSTAR CD Series, built for precise, dynamic motion control in industrial automation. It combines robust power density, advanced digital control, and flexible connectivity to serve both standalone and multi‑axis systems.

Description

CB06250 Kollmorgen SERVOSTAR CD Series Digital Servo Drive

Overview

As a member of the SERVOSTAR CD platform, the CB06250 uses a powerful DSP to execute fully digital current, velocity, and position loops with sinusoidal commutation, delivering smooth, low‑ripple motion and accurate positioning. It supports incremental encoders, resolvers, sine encoders, and Hall‑effect sensors, plus auxiliary encoder feedback for dual‑loop or master‑slave applications. The drive features a rugged, space‑saving panel‑mount design with IP20 enclosure, suited for harsh industrial environments with vibration and thermal stress.
