CR03551 by Kollmorgen

The Kollmorgen CR03551 from the CD Servostar CD Drives series is a high-performance servo drive engineered for precise motion control in industrial automation. It operates on a robust 300 V logic power supply and communicates via a SERCOS interface for real-time feedback. With a 500 µs position loop update rate, this drive ensures smooth, accurate positioning for demanding applications. Its primary function is to regulate motor torque, speed, and position with exceptional precision, making it ideal for machine tools, packaging equipment, and robotics.

This drive delivers advanced control by combining a 62.5 µs current loop update rate (16 kHz) with a current loop bandwidth of up to 400 Hz, ensuring rapid response to load changes. The commutation loop features a 250 µs update rate (4 kHz) and a bandwidth of <400 Hz>, producing a sinusoidal waveform for low-noise operation. The drive supports a ~10 V, 14-bit analog input with 1.53 mV minimum sensitivity, enabling fine control of input signals. A 400 Hz maximum commutation frequency further enhances dynamic performance, while the velocity loop long-term regulation of 0.01% (µs clock tolerance) maintains consistent speed under varying conditions.

Designed for industrial durability, the CR03551 provides a 2.5 in (63.5 mm) clearance distance top-to-bottom for effective ventilation and heat dissipation. A fault output relay rated at 1 A @ 24 VDC, 2.5 kHz bandwidth offers reliable fault signaling, and the remote enable/input accepts 12–24 V, 20 mA max for external control. Connector screw torque of 2.25 lb-in (0.25 N-m) ensures secure electrical connections. These features combine to deliver high reliability, efficient operation, and streamlined integration into automated systems, maximizing uptime and productivity in industrial environments.
