Product Description:

The HDS04.1-W200N-HA27-01-FW is a drive controller module built by Bosch Rexroth Indramat for the HDS Drive Controllers series. Installed in a machine drive rack, it accepts motion commands from a control stage and regulates motor current so that servo or spindle axes follow programmed speed and position profiles. In multi-axis systems, it acts as the power and control interface between the motion command source and the connected motor, supporting synchronized movement and stable dynamic response during operation. Because it regulates current in real time, the module can respond quickly to acceleration, deceleration, and changing load conditions during coordinated machine motion.

This module uses an analog command interface, so the master control can send continuous ±10 V references that are converted into torque-producing current. Thermal management is handled by a built-in air blower that moves cooling air across the heat sinks and helps keep the power section within its operating temperature range. The unit is part of the DIAX04 platform and is rated for 200 A of output current, which allows it to drive high-torque motors in demanding automation applications. That direct signal path is useful in systems that still use analog motion hardware, and the internal airflow keeps cooling tied closely to the power electronics.

The product is assigned to Line 04 and is listed as Version 1. It is classified as an HDS Drive Controller, which means it is intended for axis control rather than general PLC or I/O processing. These identifiers distinguish the product generation used for this drive type and separate it from other module lines in the same platform. This arrangement keeps the power stage focused on motor regulation while a separate control layer handles machine sequencing and supervisory commands.
