Product Description:

The HDS01.1-W075-D is a drive controller produced by Bosch Rexroth Indramat and positioned within the HDS Drive Controllers series. Designed to regulate power delivery to servo motors, the unit coordinates velocity and torque loops for automated machinery and interfaces with higher-level motion control systems. Its circuitry converts DC bus energy from the supply module into controlled three-phase output, enabling accurate axis movement in packaging lines, machine tools, and assembly cells. Because it serves as the power stage between the supply module and the motor, it is suited to multi-axis systems where precise acceleration, deceleration, and holding performance are required.

Thermal management is handled by a built-in air blower, so the unit removes waste heat during continuous operation without depending entirely on cabinet airflow. The power section is rated for a sustained output of 75 A, which supports continuous motor current delivery for demanding axis loads and steady torque production during normal operation. The enclosure has a protection rating of IP10, so it blocks accidental contact with larger objects but must still be installed inside a protective cabinet. This makes enclosed installation important in areas where dust, loose material, or incidental contact could reach the drive. Reliable insulation is provided by class C insulation in accordance with DIN VDE 0110, which supports operation under high thermal stress inside the power section. The unit operates within an ambient temperature range of +5 to +45 °C under normal conditions.

Additional operating limits apply at higher elevations and under warmer room conditions. Operation is permitted up to 1000 m above sea level before current derating is required, and the unit can operate at short-term room temperatures of +55 °C with reduced load. At higher elevations, thinner air reduces cooling effectiveness, so output must be limited accordingly. During storage or transport, the electronics remain stable between -30 to +85 °C, which helps protect the controller during seasonal shipping and long shutdown periods. The unit is identified as Version 1, indicating the product revision for this model.
