HDS03.2-W075N-HS77-01-FW
The HDS03.2-W075N-HS77-01-FW drive controller belongs to the HDS Drive Controllers series and is built by Bosch Rexroth Indramat. It is a modular current amplifier that links a shared DC bus to individual servo axes in a motion rack. In automated cells, the unit converts network commands into controlled phase current so motors can follow torque, speed, and position setpoints during machining, packaging, and assembly processes. The housing combines the power stage, control electronics, and cooling components in one compact module. This arrangement keeps cabinet layouts orderly and reduces the amount of external wiring between drive sections.
Communication is handled over the optical SERCOS ring, where deterministic telegrams support tightly synchronized motion cycles. Inside a DIAX04 cabinet, the controller can deliver up to 75 A of motor phase current, making it suitable for mid-range torque demands. Heat from the output stage is removed by a built-in internal air blower, which directs airflow across the heat sink to support stable operation in enclosed panels. Because it connects to a common supply structure, the unit fits naturally into coordinated multi-axis systems. The controller also supports remote diagnostics and parameter access while it remains installed in the rack.
The module occupies one slot in the rack and uses the standardized mechanical format associated with Line 03. Its control electronics are identified as Version 2, and this revision remains compatible with earlier DIAX04 supply arrangements. Standardized housing dimensions and backplane connections allow the unit to slide directly into the system frame without additional interface hardware. The rack-based layout keeps axis modules aligned and maintains a clean internal arrangement for shared power and control connections. This format is well suited to dense multi-axis cabinets where space must be used efficiently.
