Bosch Rexroth HDS03.2-W100N-HT20-01-FW AC Servo Drive Controller – HDS Series
When a servo drive fails on a production line, the consequences are immediate and costly: axes lose position, safety interlocks trip, and the entire machine comes to a controlled — or uncontrolled — stop. Every minute of unplanned downtime in a modern manufacturing cell can cost thousands of dollars in lost output, missed delivery windows, and emergency maintenance labor. The Rexroth HDS03.2-W100N-HT20-01-FW is the precision power-conversion heart of your servo axis; without it, motion simply does not happen.
Within Bosch Rexroth’s HDS (High-Dynamic Servo) drive family, the HDS03.2-W100N-HT20-01-FW occupies the high-current, high-torque tier — rated at 100 A continuous output current with the HT20 power section — making it the preferred choice for demanding axes such as heavy gantries, large rotary tables, and high-inertia spindles. Bosch Rexroth’s DIAX04 / IndraControl platform, of which the HDS series is a cornerstone, is deployed in tens of thousands of machine tools, presses, and assembly systems worldwide, cementing its reputation as one of the most field-proven servo drive architectures in global industrial automation.

Key Features & Benefits
- High Continuous Current (100 A): Handles demanding axes with large motors and high inertia loads without thermal derating under sustained duty cycles.
- HT20 High-Torque Power Section: Optimized for peak-torque applications — ideal for clamping, pressing, and heavy-load positioning where instantaneous torque demand is critical.
- Digital Field-Oriented Control: Delivers sub-millisecond current-loop response for tight velocity and position regulation, essential in synchronized multi-axis systems.
- SERCOS II Compatibility: Enables deterministic real-time communication with Rexroth IndraControl and third-party CNC/PLC masters over fiber-optic ring topology.
- Modular HDS Platform Architecture: Shares a common DC bus with other HDS/HVR modules, reducing cabinet footprint and simplifying energy recovery across axes.
- Proven Field Reliability: The HDS03.2 generation has accumulated decades of runtime in machine tools, injection molding machines, and automated assembly lines globally.
- Firmware Flexibility (FW): Standard firmware supports a broad range of motor types and control modes, reducing spare-parts complexity across mixed motor fleets.
Industry & Equipment Applications
- CNC Machine Tools: Milling centers, turning centers, grinding machines — feed and spindle axes requiring high dynamic stiffness.
- Injection Molding Machines: Clamp, injection, and ejector axes demanding precise force and position control.
- Metal Forming & Presses: Servo presses and bending machines where high peak torque and accurate ram positioning are mandatory.
- Automated Assembly Systems: Multi-axis Cartesian and SCARA robots in automotive and electronics manufacturing.
- Printing & Packaging Machinery: Register-controlled web-tension and cut-to-length axes.
- Semiconductor & Flat-Panel Display Equipment: Ultra-precise stage drives requiring low-ripple current output.
- Renewable Energy Test Rigs: Wind-turbine gearbox and generator test benches using high-torque servo loading.
