HDS02.1-W040N-HS54-01-FW
The HDS02.1-W040N-HS54-01-FW is a modular drive controller from Bosch Rexroth Indramat in the HDS Drive Controllers series. Installed in a multi-axis rack, it serves as the axis power stage and converts DC bus energy into controlled output for synchronous or induction motors. It is used in coordinated motion systems where a CNC or PLC commands torque, speed, and position control on servo or spindle axes. This role suits automated assembly lines and machining centers that require precise axis regulation. The module is intended to operate as one axis element within a larger drive system rather than as a self-contained motion package.
Communication with higher-level motion control is handled over SERCOS optical fiber, allowing cyclic setpoint exchange and diagnostic data transfer without proprietary copper cabling. The power section is rated for 40 A of continuous motor current, which supports sustained operation on the connected axis. Internal temperature is managed by a built-in air blower that moves cooling air through the heat sink fins. This cooling method helps the power section remain stable during continuous duty. As part of the DIAX04 platform, the unit is assigned to Line 02 and Version 1. These identifiers indicate the design line and release level for this controller.
The unit is classified as an HDS Drive Controller, and its logic functions are handled in a separate supply module rather than inside the axis amplifier itself. That arrangement keeps shared control functions outside the individual axis module and helps reduce heat inside the amplifier section. Placing those logic functions in the separate supply module also helps reduce electromagnetic noise inside the axis amplifier. The controller fits rack-based systems that distribute power and control tasks across multiple modules instead of placing every function in one housing. The axis module therefore remains focused on motor output and closed-loop regulation within the shared system architecture.
