CB03550 Kollmorgen SERVOSTAR CD Series Digital Servo Drive

The CB03550 is a compact, high-performance digital servo drive from Kollmorgen’s SERVOSTAR CD Series, designed for precise motion control in industrial automation. It delivers reliable, cost-effective power and advanced digital control for both synchronous and induction motors in multi-axis machines and standalone systems.

Description

CB03550 Kollmorgen SERVOSTAR CD Series Digital Servo Drive

Overview

As part of the SERVOSTAR CD platform, the CB03550 uses a powerful DSP to run fully digital current, velocity, and position loops with sinusoidal commutation. This ensures smooth, low-ripple motion and accurate positioning. It supports incremental encoders, resolvers, sine encoders, and Hall sensors, plus auxiliary encoder feedback for dual-loop or master-slave setups. The unit is built for panel mounting, with an IP20-rated rugged enclosure that withstands vibration and thermal stress in industrial environments.
