HDS03.2-W100N-HS03-02-FW
The HDS03.2-W100N-HS03-02-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. Serving as an intelligent amplifier stage, the unit supplies regulated three-phase power to synchronous or induction servo motors and relays state data back to a central motion processor. Within industrial automation lines, it governs axis acceleration, braking, and positioning accuracy for coordinated multi-axis movement. The unit regulates motor current in response to higher-level commands, helping connected axes follow programmed motion profiles during start, stop, and direction changes. Typical applications include packaging machines, transfer systems, and CNC tooling centers.
Command exchange is handled over the SERCOS fiber-optic interface, letting the controller integrate into decentralized motion networks with deterministic cycle times. Within the DIAX04 family, it uses compatible parameter structures and plug-in power modules for multi-axis systems. Thermal management is achieved by a built-in air blower, which circulates cabinet air across the heat sink to support stable operation in tightly packed racks. This cooling method does not require an external blower assembly. The power section is designed for a continuous output of 100 A, enabling direct operation of high-torque servo motors on production lines. Front-panel diagnostic LEDs provide clear status indication during operation and fault handling.
The unit belongs to Line 03 and uses Version 2. It is classified as an HDS Drive Controller, indicating its role as the regulated power and control stage in the drive system. The controller supports shared DC bus operation, allowing several amplifiers to draw from a common supply in the same system. A common supply arrangement reduces the amount of separate power hardware needed inside the rack. This layout supports coordinated operation across grouped axes.
