Rockwell Automation Ultra3000 Servo Drive System Motor and Cable Replacement Guide

In the field of industrial automation, Rockwell Automation's Ultra3000 series servo drive system relies on its high reliability and flexible communication interfaces (SERCOS, analog,...) DeviceNet、 It is widely used in precision motion control applications such as packaging, printing, material processing, and machine tools due to its indexing and extensive motor compatibility. However, with the advancement of the product lifecycle, some supporting MP series motors (especially early models using bayonet connectors) and dedicated cables have gradually been discontinued. On site engineers often face difficulties in selecting replacements for motor failures, cable damage, or system upgrades. This article is based on the official system combination document, which systematically outlines the model identification, motor matching principles, cable selection points, performance verification methods, and complete replacement process of Ultra3000 drives, helping engineers to safely and efficiently complete system maintenance.

Ultra3000 Drive Model Identification and Selection Fundamentals

Ultra3000 drives are divided into two series: 200V and 400V, each series covering multiple continuous output power levels. Correctly identifying the model of the existing driver is the first step in selecting a replacement motor.

200V level driver:

2098-DSD-005 (0.5 kW / 1.8 A rms)

2098-DSD-010 (1.0 kW / 3.5 A rms)

2098-DSD-020 (2.0 kW / 7.1 A rms)

2098-DSD-030 (3.0 kW / 10.6 A rms)

2098-DSD-075 (7.5 kW / 24.7 A rms)

2098-DSD-150 (15 kW / 45.9 A rms)

400V level driver:

2098-DSD-HV030 (3.0 kW / 5.0 A rms)

2098-DSD-HV050 (5.0 kW / 7.8 A rms)

2098-DSD-HV100 (10 kW / 16.3 A rms)

2098-DSD-HV150 (15 kW / 24.0 A rms)

2098-DSD-HV220 (22 kW / 33.2 A rms)

The model suffix also identifies the communication interface:

-SE: ERCOS Fiber Optic Interface

-DN: DeviceNet interface

No suffix or - xx: Analog command interface or index control

Key Reminder: All Ultra3000 drives require an external 12... 24V power supply for digital I/O. If the logic power needs to be maintained after the AC power is disconnected, an external+5V power supply is also required. When replacing the drive body, it is necessary to confirm that the input voltage level, power, and communication interface of the new drive are consistent with the original system.

Evolution of motor series and connector types

Ultra3000 can be matched with motors including MP series low inertia (MPL), medium inertia (MPM), food grade (MPF), stainless steel (MPS), and TL series (TLY). The most crucial evolution lies in the type of connector:

Early models (including xx2xAA): using bayonet connectors and 2090-XXNxMP series cables. These motors are gradually being phased out.

Current model (including xx7xAA): Uses SpeedTec DIN connector and 2090-CPxM7DF-xxx or 2090-CFxM7DF-xxx series cables.

Replacement principle: If the original motor is a bayonet type and has been discontinued, a new type of motor with DIN connectors must be selected, and all power and feedback cables must be replaced at the same time, as the two connectors are incompatible with each other.

Note: The cables used for high-resolution absolute feedback and incremental feedback are different. CE suffix cables are used for absolute values or rotary encoders, while CD suffix or XXNFMF are used for incremental encoders.

2.2 MPL low inertia motor (400V level)

Replace A with B for 400V level MPL motor models, such as MPL-B1510V. The matching relationship with the drive should refer to the performance specification table. For example:

MPL-B310P can be equipped with 2098-DSD-HV030 (continuous locked rotor current 2.5A, peak 7.5A)

MPL-B320P can be equipped with 2098-DSD-HV030 (continuous 4.85A, peak value 14A)

MPL-B4530K can be equipped with 2098-DSD-HV100 (continuous 9.9A, peak 31A)

When replacing, it is necessary to check whether the continuous locked rotor current of the system is less than the rated output current of the driver, otherwise it may cause overload of the driver or insufficient motor torque.

Detailed explanation of cable selection

The Ultra3000 system requires three types of cables: power/brake cables, feedback cables, and I/O/serial interface cables. Cables are classified according to their mechanical properties into standard non flex and continuous flex, with the latter used for drag chains or high bending applications.
