Bosch Rexroth CMP60 Series: Comprehensive Module Range and Technical Overview

The Bosch Rexroth CMP60 series represents a family of compact synchronous servo motors and associated drive control modules engineered for precision motion control in heavy industrial environments. Deployed across chemical processing plants, nuclear facility auxiliary systems, petroleum refinery automation lines, and large-scale manufacturing cells, the CMP60 platform has established a significant installed base globally. Its mechanical compactness combined with high torque density makes it a standard specification in applications where space constraints and dynamic response requirements are simultaneously critical. The series interfaces natively with Bosch Rexroth IndraDrive and Rexroth drive controller families, forming a closed-loop motion architecture that remains in active service at thousands of industrial sites worldwide.

The Evolution of CMP60 Architecture

The CMP60 series was introduced as part of Bosch Rexroth's second-generation compact motor platform, succeeding earlier MKD and MHD frame motor families. The original CMP60 variants utilized resolver-based feedback systems, which provided robust position sensing in high-vibration environments but imposed limitations on resolution at low speeds. Subsequent hardware revisions introduced multi-turn absolute encoders (Hiperface and EnDat 2.2 compatible), enabling single-cable motor technology (SCM) that consolidates power and feedback into one cable run — a significant wiring reduction for multi-axis machine tools and robotic cells.

The CMP60.1 designation marks the first major revision of the CMP60 frame, standardizing the connector interface and expanding the available feedback options. The SP-304 code within the ordering key specifies the stall torque class and winding configuration, while FN denotes the feedback type (in this case, a specific encoder variant), and NNNN-NW encodes options such as holding brake absence, shaft seal type, and connector orientation. As the CMP60 series has matured, Bosch Rexroth has transitioned newer machine designs toward the CMP63 and CMP71 frames; however, the CMP60 remains in production support status, with spare parts and replacement units available through authorized distribution channels and specialist suppliers such as DriveKNMS.

Compatibility considerations are critical when sourcing CMP60 replacements: the motor's feedback protocol must match the drive controller's encoder interface card. IndraDrive C (HCS) and IndraDrive M (HMS/HMD) controllers require specific firmware versions to support EnDat 2.2 absolute encoders on CMP60 frames. Resolver-based CMP60 variants are broadly compatible across older Eco Drive and DKC controller generations without firmware dependency.

CMP60 Full Catalog & Functionalities (SKU List)

The following SKUs represent verified, commonly sourced models within the Bosch Rexroth CMP60 series. Each entry reflects a distinct ordering configuration within the CMP60 motor and associated control/feedback module range.

Sourcing Hard-to-Find & Obsolete CMP60 Parts

As the CMP60 series enters its extended lifecycle phase, procurement of specific ordering variants — particularly resolver-based units and older connector configurations — has become increasingly constrained through standard distribution channels. Bosch Rexroth's official lead times for low-volume CMP60 variants can extend to 16–26 weeks, creating operational risk for facilities that require rapid replacement to minimize unplanned downtime.

DriveKNMS maintains a dedicated inventory of CMP60 series units sourced from decommissioned production lines, surplus OEM stock, and controlled refurbishment programs. Our procurement team actively tracks CMP60 availability across global industrial surplus markets, enabling us to fulfill requests for discontinued ordering codes that are no longer available through standard Rexroth distribution. For facilities operating CMP60 motors in critical process loops — where a single axis failure can halt an entire production cell — DriveKNMS provides emergency sourcing with expedited logistics to minimize mean time to repair (MTTR).

We also support customers requiring matched sets of CMP60 motors for multi-axis machine rebuilds, where feedback type, torque class, and connector configuration must be consistent across all axes to ensure drive parameter compatibility.

Quality Control for the CMP60 Range

CMP60 servo motors present specific verification challenges due to their integrated feedback electronics and precision mechanical tolerances. DriveKNMS applies a structured test protocol to all CMP60 units prior to dispatch:

Encoder integrity verification: Each unit with EnDat 2.2 or Hiperface feedback is connected to a reference IndraDrive controller and subjected to a full multi-turn absolute position cycle test. Position data consistency is verified across 10 full mechanical revolutions to confirm encoder disk integrity and signal chain continuity. Resolver-based units undergo excitation frequency sweep testing to confirm transformation ratio and phase accuracy within Rexroth specification tolerances.

Winding resistance and insulation testing: All three motor phases are measured for DC resistance balance (tolerance: ±2% inter-phase). Insulation resistance is tested at 500 VDC between windings and frame, with a minimum acceptance threshold of 100 MΩ. Units failing insulation testing are quarantined and not offered for resale.

Mechanical inspection: Shaft runout is measured with a dial indicator at the shaft extension. Bearing condition is assessed by manual rotation under axial and radial load, and by vibration signature analysis during no-load spin-up. Holding brake units (NB suffix) are tested for engagement torque and release response time.

Thermal label and nameplate verification: The motor nameplate ordering code is cross-referenced against the physical unit's internal label and encoder configuration to confirm the unit matches its documented specification before shipment.
