HDS04.2-W200N-HS91-01-FW
The HDS04.2-W200N-HS91-01-FW is a drive controller module manufactured by Bosch Rexroth Indramat in the HDS Drive Controllers series. In multi-axis machining centers and automated assembly lines, it links the servo axis power stage to higher-level motion control and regulates current to the motor. It also monitors feedback so the connected axis stays within commanded speed, torque, and position limits during coordinated machine operation. This arrangement lets the main control system issue synchronized motion commands while the drive handles fast current regulation close to the motor.
The command interface is SERCOS, so cyclic setpoints and diagnostic data travel through a fiber-optic ring instead of discrete analog wiring. A rated output of 200 A allows the unit to drive high-torque motors or support demanding axes on a common DC bus. Thermal management is handled by a built-in air blower that moves cabinet air across the heat sink without external ducting. The controller is part of the DIAX04 family, so it matches the mechanical and electrical layout used by related modules in the same rack system. Using optical communication also helps reduce susceptibility to electrical noise from switching devices elsewhere in the cabinet.
The model is part of Line 04, which places it in the fourth power class of the family and matches its physical width to the DIAX rack format. The unit is Version 2, indicating the product revision used for this controller. It does not include an integrated power supply, so supply functions must come from separate system modules. It also does not include built-in clamp functions, which keeps the controller focused on axis regulation within a modular multi-axis drive arrangement. Because supply and clamping functions are separate, the controller is intended to operate as one axis element within a larger drive system.
