Product Description:

The HDS03.1-W075N-HA06-01-FW drive controller is produced by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. Designed for multi-axis motion packs within modular automation racks, the unit regulates current and velocity loops for servo motors in machine tools, packaging cells, and material-handling stations. It converts a shared DC bus into precisely timed three-phase outputs, allowing connected axes to follow commanded speed and torque values. The controller exchanges set points and diagnostic data through an analog command channel, so velocity references arrive as ±10 V signals that the internal processor converts into PWM switching commands. This arrangement supports closed-loop motor control in systems where command generation is handled outside the drive.

Thermal management relies on a built-in air blower, which pulls cabinet air across the heat sink without external ductwork. The protective housing carries an IP10 rating, so it helps prevent accidental contact with live parts but is intended for installation inside a protected electrical enclosure. At nominal load, the power section can deliver 75 A of continuous motor current for sustained servo operation. Insulation materials fall under Class C according to DIN VDE 0110, supporting high thermal endurance in demanding duty cycles. Reliable operation is permitted in ambient temperatures from +5 to +45 °C.

For installations up to 1000 m above sea level, the controller maintains full output without derating. Above that elevation, available capacity must be reduced, and the upper ambient limit extends only to +55 °C under derated conditions. The unit is part of the DIAX04 family, which gives it the connector and system compatibility used in matching rack-based drive assemblies. When machines are parked or shipped, the electronics can withstand storage temperatures from -30 to +85 °C. Internal monitoring also checks blower operation and mains phase loss to protect the semiconductor bridge during continuous duty.
