Standard Retrofit Kits for Indramat RAC

 Why Retrofit the Indramat RAC Series?

The Indramat RAC servo drive system has been a dependable solution in industrial motion control applications for decades. Known for its rugged construction and precision performance, the RAC series was widely deployed in presses, CNC machinery, packaging lines, and automated material handling systems. However, as manufacturing demands increase and system components age, performance degradation and part obsolescence become real concerns.

Instead of replacing entire machines, standard retrofit kits offer an economical and effective solution to extend the life and capability of legacy RAC systems.

What Is a Retrofit Kit?

A retrofit kit for the RAC series typically includes updated components that either replace or supplement original Indramat hardware. These kits are designed to restore system functionality, improve performance, and support integration with modern controllers and interfaces.

Standard retrofit kits typically include:

• Replacement power modules

• Updated servo controllers

• Modernized feedback interfaces

• Improved cooling systems or fan assemblies

• Wiring harnesses and adapters for compatibility with modern PLCs

• Documentation and mounting hardware for plug-and-play installation

Benefits of Retrofitting RAC Systems

. Cost Efficiency

Avoiding a full machine replacement can save tens of thousands of dollars. Retrofitting leverages your existing mechanical infrastructure while modernizing your electronics.

. Reduced Downtime

Most kits are designed for quick installation, often without the need for major reprogramming or system redesign.

. Increased Reliability

Upgrading aging components improves thermal efficiency, circuit protection, and reduces the likelihood of drive faults or catastrophic failures.

. Support for Modern Control Architectures

Many retrofit kits allow for integration with EtherNet/IP, Profinet, and other contemporary communication protocols.

. Improved Safety & Compliance

Modernized systems can incorporate Safe Torque Off (STO) and comply with newer safety standards such as ISO 13849-1.

Common Retrofit Kit Applications

Retrofit kits for RAC drives are especially popular in systems that:

• Are built around RAC 2.2, 2.3, or 3.0 series drives

• Use TDM or KDV modules that have reached end-of-life

• Rely on older RECO interface cards

• Are no longer supported by Bosch Rexroth’s active product catalog

These kits are particularly useful for high-volume legacy equipment that still performs well mechanically but requires electrical and digital updates.

Compatibility Note

It’s critical to identify your drive model, firmware version, motor pairing (MAC/MAD), and application requirements before ordering a retrofit kit. Not all RAC systems use the same feedback types or connectors, and retrofit kits are tailored accordingly.

Wake Industrial can assist with model identification and provide retrofit options that include or exclude motor replacements depending on budget and system goals.

Upgrade Path Options

Retrofits can be done in three tiers based on your plant’s objectives:

Final Thoughts

Whether your Indramat RAC drive is showing early signs of failure, generating fault codes, or no longer supported by OEM parts, a retrofit can breathe new life into your equipment without incurring the cost or complexity of full system replacement.
