Product Description:

Bosch Rexroth Indramat manufactures the HDS03.1-W075N-HA07-01-FW, a controller in the HDS Drive Controllers series that belongs to the DIAX04 motion control family. This model regulates current and velocity loops for servo motors in industrial handling, packaging, and machining cells. It serves as the control and power interface between the cabinet supply module and the connected motor axis. Within the cabinet, it interfaces with a supply module through the series backplane and delivers real-time drive commands to connected axes, allowing coordinated movement under PLC supervision.

The controller’s continuous output stage is rated for 75 A, enabling it to energize medium-power servomotor windings without external amplifiers. Command values reach the unit through an analog communication channel, so velocity or torque setpoints are carried as differential voltage signals without fieldbus conversion delays. This arrangement suits systems that use voltage-based command signals instead of network-based control links. Thermal management relies on a built-in air blower, which draws cabinet air across the heat sink and maintains component temperature without additional ducting. The housing has an IP10 rating, which helps guard live parts against accidental contact while keeping the enclosure ventilated for airflow. Reliable operation is permitted from +5 to +45 °C, and additional cooling or output derating may be needed outside that range.

Above the nominal operating range, the unit can still function, but its current capability is reduced once ambient temperature reaches +55 °C. During storage or shipment, the electronics can withstand -30 to +85 °C, helping prevent damage during transport or inactive storage. Altitude is limited to 1000 m above sea level because lower air density reduces the effectiveness of fan cooling. The power section uses insulation class C under DIN VDE 0110, which supports higher permissible hot-spot temperatures than lower insulation classes. This product is part of line 03 and version 1 within the DIAX04 family.
