Product Description:

The HDS03.1-W100N-HS32-01-FW is an axis drive controller produced by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. Installed between a power supply module and a servo motor, it converts DC bus energy into precisely modulated three-phase currents that follow digital commands from a higher-level motion system. This function enables coordinated speed and position control in automated packaging, printing, and material-handling lines. By regulating motor current continuously, the unit helps connected axes follow commanded motion profiles with repeatable response during start, stop, and synchronized movement. This makes it suitable for applications where several axes must respond to controller commands at the same time.

It communicates over the SERCOS fiber-optic ring, so setpoint data and feedback are exchanged in real time using standardized telegrams. The power section is rated for a continuous output of 100 A, aligning the controller with medium- to high-torque servo axes that experience rapid acceleration or sustained load. Thermal management is handled by a built-in air blower, and this integral fan moves cabinet air through the heat sink without external ducting. Electrically, the unit belongs to the DIAX04 family, which gives it a compatible module format for use within that platform. Within that platform, it is part of Line 03. The fiber-optic link also helps reduce sensitivity to electrical noise inside drive cabinets.

The controller is Version 1, indicating the first production revision. The command communication interface uses optical connectors that must remain clean to maintain error-free telegram cycles. Because this optical link carries command traffic, contamination at the connectors can interrupt communication between the drive and the motion controller. Clean optical contacts also help prevent intermittent communication faults during continuous operation. Stable data exchange is important because the drive depends on uninterrupted command signals for coordinated axis response.
