HDS03.1-W075N-HT04-01-FW Bosch Rexroth Indramat

Product Description:

The HDS03.1-W075N-HT04-01-FW is a digital motion control unit produced by Bosch Rexroth Indramat within the HDS Drive Controllers series. In an automation cell, the device sits between a DIAX04 supply module and the connected servo in order to regulate current, velocity, and position loops. Its role is to translate high-level motion commands from a central controller into controlled three-phase power that moves the motor, making it a critical node for coordinated axis drives on packaging machines, machining centers, and material-handling gantries.

It communicates over the SERCOS optical ring, allowing deterministic cycle times for multi-axis synchronization. A continuous output of 75 A defines the allowable motor current before fold-back limits engage, so the unit can service high-torque transients without derating. Thermal energy created by that current is expelled by a built-in internal air blower, which draws cabinet air through the heatsink fins instead of relying on external ducting. The drive belongs to the DIAX04 controller family and therefore inherits the shared parameter structure used across that platform. Its designation as Line 03 indicates the hardware generation that pairs with specific power supplies and firmware files.

Field service considerations are simplified because the hardware is released as Version 1. When commissioning, the sequencer merely selects the standard drive list; the command interface automatically detects network speed and slot position, then negotiates telegram content with the master. Subsequent firmware upgrades are applied through the same optical ring, and the loader validates the package against the stored drive firmware checksum before flashing, guarding against mismatched releases and preserving the motion profile created during initial tuning.
