Product Description:

The HDS03.2-100N-HS12-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. It is used in modular power racks to control three-phase servo or spindle axes and to exchange motion data through a SERCOS optical interface. In automated cells, the unit converts a regulated DC bus into variable voltage and frequency so individual motors can be positioned and synchronized under CNC or PLC control. Its control stage regulates motor current so commanded torque and speed can be followed during coordinated machine motion.

In continuous operation, and with a switching frequency of 4 kHz, the controller provides a continuous output of 50 A, while operation at 8 kHz reduces that value to 35 A. Line-supply demand may rise to 60 A, and the inverter can switch at up to 1000 Hz carrier frequency across the three output phases. The output stage can modulate as much as 500 V line-to-line, which matches the DC bus levels commonly used in Indramat systems. Communication relies on the SERCOS command interface, and the product is in Line 03 and Version 2. A built-in blower provides internal air cooling, C-class insulation meets DIN VDE 0110 thermal limits, and the housing has a protection rating of IP10. Because of that enclosure rating, the unit is intended for installation inside a control cabinet rather than in exposed machine locations.

Environmental limits allow continuous duty between +5 °C and +45 °C, and the output must be derated above that range to an upper ambient limit of +55 °C. Storage and transport are acceptable from −30 °C to +85 °C, and installation is permitted up to 1000 m above sea level without extra cooling. During dynamic motion, the unit is backed by a short-circuit withstand rating of 42 kA, which supports fault tolerance in high-energy drive systems. The steel enclosure weighs 11 kg, and its three motor phases are separated by the same IP10 barrier used for the live terminals. These operating limits should be observed so airflow, altitude, and cabinet conditions remain within the intended range.
