Bosch Rexroth 80190-320-03-R 80190-318-51 AC Servo Drive – IndraDrive Series

Bosch Rexroth 80190-320-03-R / 80190-318-51 — Matched IndraDrive Axis Module for Precision Servo Motion Control

The Bosch Rexroth 80190-320-03-R / 80190-318-51 is a matched pair of IndraDrive axis drive components: a power stage assembly (80190-320-03-R) and its corresponding control/firmware board (80190-318-51). Together they form a complete single-axis servo drive module within the IndraDrive Hxx/Cxx platform — one of the most widely deployed servo architectures in European and global industrial automation. This unit is designed for panel-mount installation in coordinated multi-axis systems where deterministic torque response, fieldbus synchronization, and integrated safety functions are non-negotiable requirements.

The IndraDrive platform separates DC bus management (handled by a shared supply unit, HMV series) from per-axis power conversion. The 80190-320-03-R power stage receives regulated DC bus voltage and executes space-vector PWM modulation to deliver variable-frequency, variable-amplitude three-phase AC to the connected servo motor. The 80190-318-51 control board runs all closed-loop algorithms — position, velocity, and torque — and manages fieldbus communication, encoder signal conditioning, and STO safety logic. This architectural split allows the control board to be replaced or firmware-updated independently of the power stage, reducing maintenance downtime in high-availability production environments.

Technical Parameters

Hardware Logical Analysis

The 80190-320-03-R power stage employs an IGBT-based three-phase inverter bridge with gate-driver isolation rated to withstand common-mode transients exceeding 50 kV/μs — a critical parameter in environments where long motor cables or shared DC bus architectures introduce high dV/dt noise. The gate-driver stage uses optocoupler isolation between the low-voltage control domain and the high-voltage switching domain, preventing ground-loop currents from corrupting encoder or fieldbus signals.

The 80190-318-51 control board integrates a dedicated DSP core for real-time servo loop execution. Position and velocity loops close at 250 μs cycle time; the current (torque) loop closes at 62.5 μs — figures that place this unit in the same performance tier as purpose-built CNC axis drives. The board’s EMC design follows a multi-layer PCB strategy with dedicated ground planes for analog signal processing (encoder conditioning), digital logic, and fieldbus transceivers. Ferrite bead filtering is applied at all inter-domain signal crossings to suppress high-frequency conducted emissions without introducing phase lag in the feedback path.

The integrated regenerative braking chopper in the power stage activates when DC bus voltage exceeds a programmable threshold (typically 780 V DC at 480 V AC mains). This eliminates the need for an external braking resistor in most duty cycles, reducing panel wiring complexity and thermal management overhead. For high-inertia loads with frequent deceleration, an external resistor can be connected to the dedicated chopper terminals without any firmware modification.

Redundancy arbitration for the STO safety channel uses a dual-channel input architecture: both STO_A and STO_B must be de-energized simultaneously to achieve the safe state. A single-channel fault (one input de-energized, one not) is detected within 10 ms and logged as a diagnostic event, satisfying PLd / SIL 2 requirements without an external safety relay in most machine categories.

System Integration Benefits

• Drop-in IndraDrive ecosystem compatibility: The 80190-320-03-R / 80190-318-51 pair is electrically and mechanically compatible with existing IndraDrive supply units (HMV01, HMV02) and axis slots, requiring no DC bus re-engineering or mechanical rework during replacement.
• Protocol flexibility without hardware change: Fieldbus protocol (SERCOS III, PROFIBUS-DP, EtherCAT, CANopen) is selected via firmware load, not hardware variant. A single spare unit covers multiple machine types in a mixed-protocol plant.
• Deterministic real-time response: SERCOS III synchronization achieves jitter below 1 μs across all axes on a ring, enabling sub-micron contouring accuracy in coordinated multi-axis CNC and robotics applications.
• Integrated diagnostic transparency: The control board logs drive state, fault history, thermal margins, and encoder signal quality to non-volatile memory. IndraWorks DS retrieves this log without interrupting production, enabling predictive maintenance scheduling.
• Matched-pair traceability: Power stage and control board are tested together before shipment. Firmware revision, hardware revision, and test results are documented per unit, eliminating the compatibility ambiguity common with unmatched surplus components.
• Safe Motion without external hardware: STO, SS1, SS2, and SLS are executed on-board, reducing the safety relay count in the control cabinet and simplifying CE machinery directive compliance documentation.
• Scalable multi-axis architecture: Multiple axis modules share a common DC bus from a single HMV supply unit. Adding an axis requires only an additional module slot — no additional mains transformer or rectifier stage.
• Wide encoder compatibility: Support for Hiperface, EnDat 2.1/2.2, Resolver, and TTL/HTL incremental encoders means the drive integrates with the majority of servo motors currently in service, avoiding forced motor replacement during drive upgrades.

Quality Assurance & Global Logistics

Every unit offered through siemensplc.com is sourced from verified industrial channels and undergoes a structured incoming inspection protocol: visual examination of housing, connector, and label integrity; revision code verification against Bosch Rexroth documentation; and a functional power-on test confirming DC bus initialization and control board boot sequence. Units that do not pass all inspection stages are not listed for sale.

Packaging follows ESD-safe handling standards: anti-static bag, foam-lined inner carton, and outer corrugated carton rated for international air and sea freight. Each shipment includes a packing list, commercial invoice with HS code 8537.10, and a unit-level inspection record for customs clearance and incoming QC at the destination facility.

Logistics operations are based in Xiamen, China — a major export hub with direct access to DHL Express, FedEx International Priority, and UPS Worldwide Expedited services. In-stock units typically ship within 1–2 business days of order confirmation. Air freight transit times: 3–5 business days to Europe and North America, 2–4 business days to Southeast Asia. Sea freight consolidation is available for volume orders. All shipments are tracked end-to-end, with proactive status updates provided to the buyer.

A 12-month warranty covers manufacturing defects and verified functional failures from the date of shipment. Warranty claims are processed with a target response time of 24 hours. Replacement or credit options are available based on failure analysis outcome.
