Allen-Bradley 2098-DSD-HV220 Servo Drive Overview

The Allen-Bradley 2098-DSD-HV220 (and its variations like -SE or -DN) is a digital servo drive from the Ultra 3000 series. It is engineered to precisely control industrial motors, delivering high-performance motion for demanding applications in various industries. These servo drives are critical for achieving accurate position, velocity, and torque control in integrated motion systems.

Product Detailed Description

• Functionality:

• Precise Motion Control: Provides closed-loop control of servo motors for accurate position, velocity, and torque regulation.

• Motor Compatibility: Designed to work with Allen-Bradley's MP-Series and TL-Series servo motors (and certain linear motors/actuators).

• Digital Control: Utilizes advanced digital control algorithms for high responsiveness and performance.

• Integrated Motion: Often used in integrated motion control architectures, such as with Rockwell Automation's Logix controllers, to achieve synchronized and coordinated multi-axis motion.

• Communication Interface: Supports various industrial communication protocols, commonly SERCOS (for high-speed, deterministic motion) or DeviceNet (for distributed control).

• Protective Features: Includes built-in protection against overcurrent, overvoltage, undervoltage, overtemperature, and other fault conditions to safeguard the drive and motor.

• Key Features:

• High Voltage Input: Operates with 3-phase AC input voltage, typically ranging from 230V to 480V AC RMS.

• High Output Current: Offers significant continuous and intermittent (peak) output current ratings to handle high-torque applications.

• Flexible Control Modes: Supports various control modes including indexing, point-to-point positioning, and coordinated motion.

• Encoder Feedback: Relies on motor feedback (typically from an encoder) for precise closed-loop control. Supports multi-turn absolute encoders.

• Programmable: Configurable via software like UltraWare for tuning and parameter setup.

• Digital I/O: Features optically isolated digital inputs and outputs for general purpose control and signaling.

• Serial Communication: Includes a serial port for RS-232 or RS-485 communications (for non-networked applications).

• Rugged Construction: Built for industrial environments, designed to handle extreme loads and high-inertia motion systems.

• Auxiliary Power Supply: May require or support an auxiliary power supply for digital I/O operation or to maintain logic power during AC line voltage removal (for position maintenance).
