Product Description:

The HDS04.1-W200N-HA04-01-FW is a drive controller produced by Bosch Rexroth Indramat within the HDS Drive Controllers series. It serves as an axis amplifier that links servo or main-spindle motors to the DIAX modular automation platform. In multi-axis installations, it forms the power stage between the shared bus supply and the motor. By supplying regulated current and motion commands, it helps CNC machines and material-handling cells maintain tight speed and position control during continuous production. The unit is intended for coordinated motion tasks where stable axis response is required across changing loads and acceleration demands.

This module exchanges reference values through an analog signaling path, so command voltages from a master drive or PLC are converted directly into torque demand without an added digital command stage. It belongs to the DIAX04 family, so its backplane connections match other fourth-generation units in the lineup. Thermal management is handled by a built-in air blower that moves cabinet air across the heat sink and supports reliable cooling inside the enclosure. A continuous output capability of 200 A allows the controller to drive large synchronous or induction motors during rapid acceleration and sustained load changes. The unit is part of Line 04, which places it in the fourth design line of this controller platform.

The unit is Version 1. Its analog control section supports ±10 V references, which makes it suitable for systems that still use legacy voltage-based motion commands. It is compatible with shared DIAX bus supplies used in modular drive assemblies. Because cooling is handled internally, no liquid cooling circuit or external air duct is required for normal operation. This layout keeps the installation focused on cabinet airflow and standard power distribution rather than additional thermal hardware.
