HDS04.2-W200N-HA12-01-FW
The HDS04.2-W200N-HA12-01-FW drive controller is manufactured by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. It serves as a modular power and motion unit in multi-axis systems, converting supply bus energy into regulated motor current while forwarding reference values to connected servo drives and maintaining the response needed for synchronized motion under changing load conditions. In machining centers, handling lines, and assembly cells, this role supports precise position and speed control where several axes must operate in a coordinated manner throughout repetitive production cycles.
The power stage can deliver up to 200 A, making the controller suitable for high-torque servo motors. Command data arrives through an analog channel that accepts proportional voltage setpoints from legacy PLCs as well as manual potentiometers. This arrangement allows simple reference control without requiring digital network communication for basic speed or position commands in older machine architectures. The unit is part of the DIAX04 family, and it is identified as Version 2 for this model. The setpoint and feedback path is referred to as the command interface, which distinguishes this controller from units that use digital communication protocols.
Thermal regulation is handled by a built-in air blower, and the integrated fan moves enclosure air across the heat sinks so no external ducting is required. The airflow stays within the housing, which keeps the cooling method integrated into the controller assembly. The code element 04 identifies the product line and matches supply modules that use the same DC bus voltage and protective circuitry. Power electronics and control logic are combined in one housing, which helps conserve cabinet space in dense multi-axis installations and keeps the controller layout straightforward.
