Product Description:

The HDS03.1-W100N-HS37-01-FW is a modular drive controller produced by Bosch Rexroth Indramat and located within the HDS Drive Controllers series. In an industrial automation cell, this unit serves as the power stage that converts logic-level commands from motion controllers into controlled three-phase output for servo motors. It accepts command information from the control system and shapes the electrical output sent to the connected motor. By managing acceleration, speed, and braking energy, it supports coordinated multi-axis motion in packaging equipment, machining centers, and assembly lines.

Real-time motion data is exchanged through SERCOS, a fiber-optic serial bus that supports deterministic update cycles. The unit belongs to the DIAX04 controller family, so parameter cards, back-plane pinouts, and diagnostic codes align with that platform. Fiber-optic communication also helps maintain signal quality in electrically noisy machine environments. The power module occupies Line 03 in the series architecture. Thermal energy is removed by a built-in air blower, which draws cabinet air across the heat sink and avoids the need for external ducting. During operation, the device can deliver up to 100 A of output current, allowing it to accelerate large motors or multiple parallel axes without exceeding normal operating limits.

The drive controller is Version 1, and this revision identifies the product generation used for the unit. Functionally, the hardware is classified as an HDS Drive Controller, so it can be installed with other axes in the same platform. The unit does not include an integrated power supply or brake resistor, so those functions are handled by separate system components in the drive assembly. Separate supply and braking modules are commonly used in modular drive systems where each section performs a specific task. Its modular format also supports use in multi-axis racks where several drive sections share a common system layout.
