Technical Specifications

Note: Electrical parameters such as rated current and supply voltage vary by sub-variant. Confirmed specifications are provided upon request based on the unit's nameplate data. No parameters are assumed or fabricated.

Solving the Discontinued Hardware Crisis

The IndraDrive Cs platform was widely deployed in precision manufacturing, packaging machinery, and semiconductor handling equipment throughout the 2000s and 2010s. Its compact form factor and SERCOS II integration made it the preferred choice for machine builders who needed deterministic motion control in space-constrained cabinets.

Bosch Rexroth has since transitioned its product roadmap to the IndraDrive Mi and IndraDrive C/M families, leaving CSH01-series users without an OEM supply path. The SERCOS II communication protocol itself is no longer supported in current-generation drives, which means a like-for-like swap is impossible without replacing the motion controller, rewriting the PLC program, and recertifying the machine — a process that takes months and carries significant risk of introducing new faults into a previously stable system.

For plant managers operating equipment built around this drive, the only cost-rational strategy is to maintain a verified spare inventory. A single unit held in climate-controlled storage can extend the operational life of an entire production cell by 5 to 10 years, deferring a capital expenditure that may run into the millions.

Condition & Reliability Assurance

Every CSH01.1C-SE-EN2-NNN-NNN-NN-S-NN-FW unit processed by DriveKNMS passes a structured 5-step inspection protocol before it is offered for sale:

• Step 1 – Electrolytic Capacitor Assessment: DC bus and filter capacitors are inspected for bulging, leakage, and ESR degradation. Capacitors showing age-related deterioration are flagged and the unit is reclassified accordingly.
• Step 2 – Firmware Version Verification: The firmware revision is read and documented. Units are matched to customer requirements where firmware compatibility is critical.
• Step 3 – Pin and Connector Inspection: All I/O connectors, feedback ports, and power terminals are examined under magnification for corrosion, bent pins, and contact oxidation.
• Step 4 – Power-On Functional Test: Where test bench infrastructure permits, units are powered and checked for fault-free initialization and communication response.
• Step 5 – Condition Grading and Documentation: Each unit is assigned a condition grade (New Surplus, Refurbished, or Tested Used) and shipped with a condition report. No unit is sold without a documented grade.

Key Features for System Maintenance

• Drop-in replacement: The CSH01.1C-SE-EN2-NNN-NNN-NN-S-NN-FW is a direct mechanical and electrical substitute for the original unit. No cabinet modifications are required.
• No reprogramming required: SERCOS II node address and drive parameters are stored in the motor encoder or external parameter memory (depending on system configuration). In most installations, the replacement drive reads existing parameters automatically on first power-up.
• Avoids engineering reconstruction costs: Retaining the original drive platform eliminates the need for motion controller replacement, PLC code rewrite, and machine recertification — costs that dwarf the price of a spare drive by orders of magnitude.
• Long-term storage compatibility: Units can be stored in controlled environments for extended periods. DriveKNMS provides storage recommendations upon request for customers building multi-year spare inventories.
