HDS03.2-W100N-HT27-01-FW
The HDS03.2-W100N-HT27-01-FW is a drive controller module produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Installed on a shared power-supply rack, it interfaces with higher-level motion processors to distribute controlled current to multiple servo axes, enabling coordinated positioning, velocity, and torque control in automated production equipment. Its role is to execute real-time drive commands, monitor motor feedback, and protect connected axes against overloads during production cycles. In closed-loop systems, that combination allows several axes to respond together while the controller maintains the commanded motion profile.
The module exchanges command and feedback data over the SERCOS serial interface on an optical ring, so axis status and control data travel on a deterministic channel that resists electrical noise. This communication method supports cyclic command updates and consistent feedback exchange between the controller and the rest of the motion system. For demanding motor phases, the controller can deliver up to 100 A, a level suited to mid-range and large servomotor applications. Thermal management relies on a built-in air blower, which circulates cabinet air through the heat sink and supports prolonged duty cycles. The unit is part of the DIAX04 family, which gives it common backplane geometry and diagnostic behavior with related motion modules. It is identified as Version 2.
The controller is part of Line 03, which uses the slot arrangement and power-bus connection assigned to this design line in the HDS cabinet. An onboard EEPROM stores axis parameters so operating data remains available within the unit after setup. Front-panel status indicators show operating and fault conditions, helping users identify network or axis states quickly without opening the cabinet.
