Technical Specifications

Note: Electrical parameters not independently verified. Specifications above are derived from Bosch Rexroth IndraDrive ordering code conventions. Do not substitute parameters from other control section variants.

Solving the Discontinued Hardware Crisis

The Bosch Rexroth IndraDrive platform was deployed extensively in precision manufacturing — automotive body shops, semiconductor handling equipment, packaging lines, and multi-axis machining centers — throughout the 2000s and 2010s. The control section (SH module) is the intelligence layer of the drive: it manages encoder feedback, fieldbus communication, and motion sequencing. When this board fails, the drive is inoperable regardless of the condition of the power section.

The R91133022C7 is compatible with IndraDrive C and IndraDrive M power sections that accept the SH01.1C control section format. Before installation, verify the firmware version against your drive's existing configuration to ensure parameter compatibility.

Condition & Reliability Assurance

Discontinued control electronics require a more rigorous incoming inspection than current-production parts. DriveKNMS applies a 5-step QA protocol to every SH-series control board before it is offered for sale:

• Step 1 – Visual and mechanical inspection: Board examined for physical damage, connector pin condition, and PCB integrity. Boards with bent pins, cracked substrates, or evidence of thermal events are rejected.
• Step 2 – Electrolytic capacitor assessment: Capacitors on legacy control boards are a primary failure mode after years of storage or field use. Each board is assessed for capacitor bulging, leakage, and ESR deviation. Boards with suspect capacitors are either reconditioned or removed from inventory.
• Step 3 – Firmware version verification: The firmware revision is read and documented. Customers receive the firmware version with their order so compatibility with the target drive can be confirmed before installation.
• Step 4 – Pin and connector corrosion check: All edge connectors and interface pins are inspected under magnification for oxidation and corrosion. Affected contacts are cleaned to IPC standards where remediation is possible.
• Step 5 – Functional bench test (where test fixtures are available): Boards are powered and checked for basic initialization and communication response. Test results are documented and available on request.

Key Features for System Maintenance

• Drop-in replacement: The R91133022C7 SH01.1C control section installs directly into compatible IndraDrive power sections without mechanical modification.
• No PLC reprogramming required: Replacing the control section with an identical part number preserves the existing drive parameter set. The host PLC program, motion profiles, and fieldbus node configuration remain unchanged, provided firmware versions are matched.
• Avoids engineering re-commissioning costs: A like-for-like control board swap eliminates the need for a drive manufacturer's service engineer, saving both time and cost compared to a full drive replacement.
• Preserves existing wiring infrastructure: No changes to motor cables, encoder cables, or fieldbus wiring are required. This is particularly significant in installations where cable routing is complex or access is restricted.
• Supports long-term maintenance planning: Purchasing multiple units for critical axes allows maintenance teams to establish a documented spare parts reserve, reducing exposure to future secondary market price volatility for this discontinued part.

How do I confirm the part is genuine and not counterfeit?
All boards supplied by DriveKNMS are sourced through documented supply channels. Bosch Rexroth part markings, date codes, and serial numbers are present and unaltered on genuine units. We do not supply remarked or cloned boards. Customers may request photos of the specific unit prior to purchase.

Can DriveKNMS source other IndraDrive spare parts?
Yes. DriveKNMS specializes in obsolete and hard-to-find industrial automation components across multiple brands. If you have additional Rexroth part numbers required for your maintenance program, contact us with your full list.
