HDS02.1-W040N-HA27-01-FW
The HDS02.1-W040N-HA27-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. Deployed in modular multi-axis racks, it supplies closed-loop current and velocity regulation so connected servomotors can position loads, follow speed profiles, or provide constant torque in automated packaging lines, gantry stages, and tooling cells. By translating external reference signals into precise PWM outputs, the unit forms the power interface between a motion control platform and the mechanical axis it drives. This arrangement lets the controller respond quickly to changing axis demand during indexing, speed holding, and load disturbances.
The command channel relies on an analog reference, so drive behavior is governed by continuously varying voltage or current setpoints from the supervisory controller. This allows straightforward integration with PLC cards that supply ±10 V signals. That input style is useful in systems that generate command values from separate motion cards or process controllers instead of a digital fieldbus. Motor windings are energized through a rated output of 40 A, which is the maximum continuous current available to the attached motor under normal thermal conditions. Internal temperature is moderated by a built-in air blower that moves cabinet air across heat sink surfaces as load rises.
The controller is part of the DIAX04 family, so it shares a common platform with related axes in the same system and supports consistent operating behavior across a multi-axis rack. Within the product coding, the unit belongs to Line 02. It is supplied as Version 1. Proper enclosure airflow remains important because the controller releases heat into the cabinet rather than to an external heat exchanger, and no external fan or liquid cooling circuit is required.
