HDS02.2-W040N-HS04-02-FW
The HDS02.2-W040N-HS04-02-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Within an automation cell, it acts as the closed-loop power stage between a higher-level motion processor and individual servo motors, converting setpoint data into regulated three-phase output currents that move machine axes. This arrangement supports coordinated torque, speed, and position control across multiple axes in automated equipment. It also helps reduce the need for separate analog amplifier hardware, which keeps cabinet layouts more compact and simplifies internal wiring paths.
The controller exchanges real-time commands over SERCOS, allowing deterministic updates for trajectory following and diagnostic communication. It belongs to the DIAX04 family, so its plug-in backplane and encoder cabling match companion modules used for auxiliary axes in the same system. Cooling is provided by a built-in air blower that pulls air through the heatsink during continuous operation. The power section has a continuous output of 40 A, which suits medium-frame servomotors that require substantial current during acceleration and load changes. This controlled power delivery supports stable axis response during positioning, speed regulation, and repeated machine cycles.
The unit is part of Line 02 in the product range. It is also identified as Version 2, which distinguishes this release within the drive family without changing its role as a modular axis controller. Its format is intended for use in multi-axis racks where several drive modules share a coordinated control structure. The design supports consistent module integration, orderly cabinet assembly, and clear separation between motion control functions and motor power delivery. It is suited to automated systems that rely on repeatable servo performance throughout normal production operation.
