Product Description:

The HDS04.1-W200N-HS25-01-FW is a drive controller manufactured by Bosch Rexroth Indramat and supplied as part of the HDS Drive Controllers series. Installed in a multi-axis cabinet, it acts as the closed-loop power module for one servo axis. The unit receives cyclic setpoint telegrams from a motion master and converts the shared DC bus voltage into precisely timed switching patterns that control the torque and speed of the connected motor. By performing high-power switching locally while staying synchronized with the central controller, it supports compact and scalable machine layouts. This arrangement allows multiple axes to share a common cabinet power structure while keeping motor control at the drive level.

For command exchange, the controller uses the SERCOS fiber-optic interface, which provides deterministic position and velocity data during each communication cycle. Membership in the DIAX04 family keeps its mechanical outline and backplane connectors consistent with matching supply modules of the same generation. Thermal regulation is provided by a built-in air blower that draws enclosure air through the heat sink channel without external ducting. That airflow removes switching losses from the power section and helps maintain stable internal temperatures during continuous operation. Electrically, the drive is rated for a continuous output of 200 A, allowing it to energize large-frame servo motors or parallel-wound stator phases under nominal ambient conditions.

The product is part of Line 04 in the series. It is Version 1. The unit is an HDS Drive Controller, so it serves as the drive-side control and power stage for closed-loop servo operation. Its configuration is intended for use on a shared DC bus, which suits centralized multi-axis systems that distribute power from a common supply section. Cooling is integrated into the module housing, so no separate external cooling assembly is required for the drive itself.
