Product Description:

The HDS03.1-W100N-HT25-01-FW is a drive controller manufactured by Bosch Rexroth Indramat and placed within the HDS Drive Controllers series. It is part of the DIAX04 motion control platform. The controller converts drive commands from central motion logic into regulated power for servo axes, making it a core element in industrial automation racks that require synchronous, closed-loop speed and torque control.

It interfaces with higher-level motion controllers over the SERCOS fiber-optic bus, so setpoints and diagnostics are exchanged with deterministic timing. The power section is rated for a continuous motor phase current of 100 A, enabling the unit to drive large servo motors under nominal operating conditions. Thermal energy is expelled by a built-in air blower, which helps keep the heat sink temperature stable. The housing has an IP10 protection category according to DIN 40 050, indicating basic protection against solid objects while allowing open ventilation for the blower path. Standard operation is specified within an ambient range of +5 to +45 °C. The controller is part of Line 03 of the HDS family and is supplied as Version 1.

In extended service, the electronics may remain energized up to +55 °C, but output must be derated to stay within thermal limits. Installation altitude is limited to 1000 m above sea level, because thinner air reduces cooling effectiveness and dielectric strength. Insulation materials meet class C per DIN VDE 0110, allowing the controller to operate with high internal temperature tolerance. During storage and transport, the unit tolerates ambient extremes from -30 to +85 °C, which supports handling in non-climate-controlled spaces. These operating and storage limits should be observed whenever the controller is installed, moved, or kept in reserve.
