Product Description:

The HDS02.1-W040N-HS54-01-FW is a drive controller manufactured by Bosch Rexroth Indramat within the HDS Drive Controllers series. It serves as the power and regulation module in DIAX04 multi-axis systems, converting incoming three-phase supply energy into controlled motor current so that machine tools, printing lines, and material-handling systems can execute precise motion profiles. In closed-loop operation, it supports stable torque and speed control for coordinated industrial motion. This type of controller is used where multiple axes must respond predictably to command changes while maintaining consistent motor behavior under varying process loads.

This controller exchanges setpoints and status data over the SERCOS fiber-optic interface, which supports deterministic cycle times and helps maintain noise-resistant communication between the drive and the higher-level control. A continuous output of 40 A allows the connected axis to deliver strong dynamic torque during acceleration and load changes. Thermal management is handled by a built-in air blower that moves cabinet air across the heat sinks during sustained operation. The housing meets IP 10, and the permitted ambient temperature range is +5 to +45 °C, so the unit is intended for installation inside a closed electrical cabinet rather than in an exposed machine location.

The unit can be mounted up to 1000 m above sea level without derating, and operation remains permissible when the surrounding air is managed so the casing does not exceed +55 °C. During storage, it can withstand temperatures from −30 to +85 °C without harming internal insulation materials or electrical separation. The windings and internal wiring use insulation class C in accordance with DIN VDE 0110, which supports elevated thermal endurance in compact multi-axis cabinets. These limits are useful in control cabinets where several power devices operate side by side and airflow management must remain consistent across the assembly.
