Allen-Bradley 2098-DSD-150-SE Ultra3000 Servoantrieb

Product Overview

The Allen-Bradley 2098-DSD-150-SE provides high-performance motion control for demanding industrial applications. This Ultra3000 servo drive delivers 65 Amps of continuous current and 150 Amps of intermittent peak current to handle high-inertia loads. It operates on a three-phase 230-480V AC input and integrates SERCOS interface technology for precise synchronization with Logix controllers. The unit features an internal shunt and auxiliary power supply, simplifying system wiring. We supply this item as a 100% Brand New, factory-sealed unit.

Technical Specifications

Engineering Advantages

High-Power Motion Control
The 2098-DSD-150-SE drives large servo motors with 65A of continuous current. For dynamic moves requiring rapid acceleration, the drive supplies up to 150A intermittently. This power reserve ensures your machine maintains path accuracy and cycle times even under heavy cutting loads or high-speed indexing.

Integrated SERCOS Interface
This drive connects directly to ControlLogix or CompactLogix controllers via the SERCOS fiber optic network. This digital interface eliminates electrical noise interference common in analog systems. It allows for precise coordination of multi-axis motion, enabling complex camming and gearing applications with microsecond-level synchronization.

Built-In Power Management
The unit includes an internal shunt resistor (9.1 Ohms) that dissipates regenerative energy during deceleration. This feature prevents bus overvoltage faults (triggered at 452V DC) without requiring external braking resist. Additionally, the auxiliary power supply keeps the logic circuits active while the main bus is disabled, facilitating faster startup and safer troubleshooting.

FAQs

Q: What input voltage does the 2098-DSD-150-SE require?
A: The drive requires a three-phase AC input ranging from 230V to 480V RMS. It automatically adapts to the supplied voltage within this range, making it suitable for various industrial power grids.

Q: Can I use this drive for single-axis or multi-axis applications?
A: Yes. The SERCOS interface supports daisy-chaining multiple drives on a single fiber ring. You can use the 2098-DSD-150-SE as part of a coordinated multi-axis system or as a standalone high-power axis.

Q: Does this drive have an internal shunt?
A: Yes. The 2098-DSD-150-SE features a 9.1 Ohm internal shunt. This handles moderate regenerative energy. For applications with extremely high inertia or vertical loads, you may still need to verify if an external shunt is required based on your specific duty cycle.

Q: What is the difference between continuous and intermittent current?
A: Continuous current (65A) is the amount the drive can supply indefinitely without overheating. Intermittent current (150A) is the peak output available for short durations (typically seconds) to accelerate loads or overcome friction.
