HDS03.1-W100N-HS28-01-FW
The HDS03.1-W100N-HS28-01-FW is a drive controller produced by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. Within a multi-axis drive rack, this controller supplies regulated power to servo axes and accepts high-level motion commands from a master. It functions as the axis amplifier that closes the torque and velocity loops for industrial robots, packaging lines, and handling machines. By converting DC bus energy from the shared supply into precisely timed three-phase outputs, it supports rapid acceleration, deceleration, and accurate positioning in automated equipment. This arrangement lets the rack distribute power centrally while each axis receives controlled current for coordinated motion.
Hardware communication with upstream PLCs is carried out through the SERCOS optical ring, giving deterministic cycle times and standardized telegram structures. The unit is part of the DIAX04 family, so it uses the same platform architecture as related drives in the system. Thermal management is handled by a built-in air blower, which pulls cabinet air through the heat sink so the module can maintain its full 100 A continuous output without external ducting or water cooling. The blower responds to heat sink temperature and removes switching losses during extended high-current operation. Because command data is exchanged in a synchronized format, the controller can follow coordinated motion profiles without timing drift between axes.
This unit is part of Line 03 and is marked as Version 1. It is classified as an HDS Drive Controller and must be used with a compatible supply unit and a compatible servo motor. The module does not operate as a stand-alone inverter because it relies on the power infrastructure of the drive rack. The line and version codes indicate the product generation used for this controller.
