HDS02.1-W040N-HS47-01-FW
The HDS02.1-W040N-HS47-01-FW is a modular drive controller from Bosch Rexroth Indramat in the HDS Drive Controllers series. In a multi-axis automation rack, the unit regulates current and velocity loops for connected servo axes, allowing coordinated positioning, speed control, and torque control on production machinery. It converts digital motion commands from a higher-level controller into regulated three-phase power for attached motor modules, making it suitable for CNC machines, printing presses, and assembly cells. Closed-loop regulation helps the axis respond to changing loads while keeping commanded motion profiles stable during operation.
The controller exchanges real-time motion data over the optical SERCOS interface, so position values and command data move across a deterministic bus without additional field wiring. It is used with the DIAX04 family, and the product is part of Line 02. The power stage is rated for 40 A of continuous output current, allowing the unit to drive medium-frame servo motors that require sustained torque during rapid acceleration. This current capacity supports applications that run repeated motion cycles without immediate thermal derating. Thermal management relies on a built-in internal air blower, which pulls cabinet air through the heat sink to help control semiconductor temperature.
The unit is Version 1 and is categorized as an HDS Drive Controller. This designation indicates that it is intended for use in a rack-based drive system rather than as a standalone inverter. The design uses standard backplane dimensions and I/O pinouts used throughout the product line, which helps maintain mechanical and electrical consistency in the rack. That layout also supports orderly internal wiring between control modules and power sections inside the cabinet.
