Product Description:

The HDS03.1-W075N-HS79-0-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. In an industrial automation rack, it receives digital motion commands from a master control network and generates controlled current for connected servo modules. The device functions as a programmable axis interface, translating position, velocity, and torque requests into regulated output for machinery such as packaging lines, gantry drives, and machining centers. This role allows the controller to support coordinated axis movement where repeatable response and stable command tracking are required.

Digital data exchange is handled through a SERCOS fiber-optic interface, allowing synchronous command transmission at high bus speeds. During operation, the controller can supply up to 75 A of regulated output current to the power section, so associated conductors and protective devices must match that load. Heat produced by the power electronics is removed by a built-in internal air blower, so the unit relies on cabinet airflow rather than an external cooling circuit. The housing carries an IP 10 rating, which limits the controller to protected indoor enclosures without exposure to dripping water or conductive dust. Reliable performance is maintained within an ambient range of +5 ... +45 °C, and operation above that range requires output derating.

The controller belongs to the DIAX04 family, so it uses the same platform architecture as other axis modules in that system. It can be installed up to 1000 m above sea level without adjustment to cooling or switching characteristics. Internal insulation materials are rated as class C according to DIN VDE 0110, supporting the thermal stress that can occur during rapid acceleration cycles. If the surrounding air temperature rises toward +55 °C, the unit can remain in service when the permissible current is reduced accordingly. This limitation helps protect the power semiconductors during sustained operation in warmer enclosures.
