KOLLMORGEN CR06550 High-precision digital servo amplifier

Introduction

The Kollmorgen CR06550 is a high-precision digital servo amplifier from the legacy Servostar CD series (Compact Drive family). Engineered for high-bandwidth control of synchronous and permanent-magnet industrial brushless servo motors, this single-axis drive features exceptional loop response dynamics and robust torque management capabilities.

Equipped with a flexible processing architecture, the CR06550 provides precise speed, acceleration, and position loop execution.

 Designed with a standard analog interface and versatile feedback capability, it serves as a highly reliable drop-in solution for legacy lines, retrofits, and high-duty production machinery.

Technical Parameter Table

Unique Product Description

The Kollmorgen CR06550 stands out in the control market due to its ruggedized analog communication interface coupled with integrated software resolver and sine encoder calibration options. This allows the drive to achieve extremely smooth torque delivery and low harmonic distortion even under changing mechanical resonance states.

Its optimized internal switching circuit minimizes thermal overhead, maintaining an impressive 95% operating efficiency. Housed in a lightweight, compact chassis weighing under 2 kg, the CR06550 easily fits into high-density legacy control cabinets, eliminating the cost and space required for extensive multi-axis layout redesigns.

Product Advantages and Features

Dual-Input Flexibility: Operates reliably on either single-phase or three-phase line inputs (115V/230V), providing versatility across different electrical grids.

Advanced Feedback Interface: Supports high-resolution sine encoders and encoder emulation alongside standard resolver feedback for highly adaptable loop tracking.

Extended Input-Output Layout: Features an expanded I/O interface for comprehensive handshake signals, error fault monitoring, and remote enable control.

High Torque-to-Size Ratio: Delivers up to 18A peak current from a compact, narrow-width frame, saving valuable backpanel real estate.

Long-Term Reliability: Known for industrial-grade durability, with components engineered to run continuously in heavy factory environments.

Application Cases

Metal Forming and Stamping: Manages high-impact feed control and positioning loops on stamping presses and bending machines.

Food Processing Machinery: Controls dynamic conveyor axes, indexing multi-head fillers, and automated slicing systems requiring rapid stop-start profiles.

Hoisting and Gantry Systems: Powers compact vertical lifting modules and Cartesian pick-and-place systems requiring steady holding torque.

Packaging and Cartoning Modules: Provides highly repetitive positioning and synchronization for packaging lines and end-of-line sealing machines.

Installation and Maintenance

Installation Guidelines

Cabinet Protection: The CR06550 has an IP20 protection rating. It must be mounted vertically inside a clean, dry, enclosed industrial electrical cabinet rated for IP54 or better to avoid airborne particle entry.

Thermal Clearances: Allow sufficient clear spacing above and below the amplifier chassis to facilitate proper convection cooling and unrestricted airflow.

Grounding Infrastructure: Ensure a heavy, low-impedance star ground configuration connecting the drive baseplate to the main subpanel to prevent high-frequency electrical noise from d
