HDS04.2-W200N-HS78-00-FW
The HDS04.2-W200N-HS78-00-FW is a controller produced by Bosch Rexroth Indramat and supplied within the HDS Drive Controllers series. Classified as an axis drive controller, it regulates power and motion in industrial automation systems by translating digital commands into controlled motor currents. In automated systems, this role lets the unit coordinate motor response with commands from the host control. The unit links to higher-level control hardware through a fiber-optic network, which supports the exchange of motion commands and status data. It also includes onboard fault diagnostics, which help operating conditions be tracked directly from the controller. This helps the connected axis respond predictably during speed and positioning tasks.
The SERCOS fiber-optic bus ensures deterministic communication even in multi-axis installations. The controller belongs to the DIAX04 drive family, so its parameter structure and mounting dimensions match the shared cabinet platform used by related modules. Continuous load can be supplied at 200 A, which is the maximum output current the power stage can deliver without exceeding thermal limits. Cooling is provided by a built-in air blower, which removes heat directly from the power semiconductors and eliminates the need for external ducting. The unit is Version 2, placing it in the second product generation for this control design. That output capacity allows the controller to operate large induction or synchronous motors from a single module.
The unit is part of Line 04, which places it in the mid-power segment and keeps slot dimensions and bus connectors consistent with companion supply modules. The communication interface remains optical, so status words and alarms can pass through the fiber-optic link without additional electrical signal wiring. Electrical isolation and error-handling routines are integrated to protect the power stage during overcurrent or bus faults.
