Product Description:

The HDS03.1-W100N-HA19-01-FW is a modular drive controller built by Bosch Rexroth Indramat for the HDS Drive Controllers series. Within an industrial automation rack it interfaces with shared DC buses, feedback cables, and control cards to regulate servo or spindle axes. The unit converts the supplied intermediate circuit voltage into controlled three-phase output and executes torque, velocity, or position loops commanded by a motion controller. By handling high-current switching internally, it functions as the final actuator in the control chain, enabling CNC machines, material-handling gantries, and packaging equipment to achieve repeatable and time-synchronized motion profiles.

The command channel uses ANALOG reference signals, so ±10 V inputs from a PLC or numerical control set the instantaneous target for current, speed, or position. As part of the DIAX04 controller family, the module shares back-plane connectors, diagnostics, and firmware structure with other HDS/HDD units, simplifying multi-axis builds. A built-in internal air blower forces cooling air across the IGBT heat sinks, allowing the electronics to remain inside sealed cabinets without external fans. Under these thermal conditions the continuous output remains 100 A, a figure that determines the largest motor size the drive can energize while staying within semiconductor limits. Bosch labels the hardware as Line 03, identifying the third mechanical and electrical iteration that adopts revised power semiconductors and monitoring circuitry.

This particular controller is released as Version 1, meaning its baseboard revision aligns with the first firmware generation accepted by the DIAX04 platform. The manufacturer Bosch Rexroth Indramat lists no alternative configurations for this order code; the ‘Other versions’ field therefore reads None, which removes compatibility checks when installing replacements. Because it fits the standard HDS Drive Controllers series envelope, the module retains uniform mounting holes, SERCOS ribbon ports, and LED diagnostics, so retrofitting into existing drives only requires exporting parameters from the predecessor unit.
