HDS03.2-W100N-HS78-00-FW
The HDS03.2-W100N-HS78-00-FW is a modular drive unit manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. It works as an axis controller that converts command data into precisely regulated motor current, allowing coordinated positioning in machining centers, material-handling robots, and automated presses. By combining closed-loop regulation with built-in thermal monitoring and diagnostic supervision, the unit supports stable torque and speed control during changing load conditions. Its modular format also suits multi-axis drive racks where several controlled axes must operate together without losing response accuracy. It is used where repeatable velocity control and accurate positioning are both required.
Command data enter through the SERCOS fiber-optic interface, so setpoints and status words remain synchronized across the drive bus at predictable update intervals. The power section is rated for a continuous output of 100 A, which allows the controller to supply large synchronous motors during sustained acceleration, steady running, and regenerative phases. Heat is managed by a built-in air blower that moves cabinet air through the heat sink without external ducting. The unit belongs to the DIAX04 platform and is configured as an HDS Drive Controller for use with compatible supply modules in a multi-axis rack.
Within the product hierarchy, the drive is part of Line 03, which corresponds to the mechanical width and power terminal spacing used when the module is installed beside supply modules. The unit is identified as Version 2, marking the product generation used for this controller. Its front panel uses the same keypad and diagnostic LED arrangement found on companion axes, so operating states and fault indications appear in a consistent format across the rack. This arrangement helps keep module status easy to read when several axes are mounted side by side.
