HDS02.1-W040N-HA36-01-FW
The HDS02.1-W040N-HA36-01-FW drive controller is produced by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. When mounted in a multi-axis cabinet, it links a shared DC bus supply to individual motor channels and serves as the power stage for coordinated motion. By translating external motion references into regulated current and voltage loops, the unit directs synchronous or induction motors to index, synchronize, or hold position in packaging, machining, and material-handling equipment. It operates as the link between the cabinet power section and the connected motor, allowing speed and torque commands to be carried out with repeatable control. This arrangement suits systems where several axes must respond consistently to commands from a higher-level control.
The command stage accepts an analog interface, so ±10 V setpoints from the machine control are processed directly by the power electronics. A continuous phase current of 40 A is the maximum the module can supply without exceeding its thermal limit during normal operation. To dissipate switching losses, a built-in internal air blower forces air across the heat sink and supports stable cooling inside the enclosure. The controller belongs to the DIAX04 family, which uses a common platform for multi-axis drive hardware. Within that family, it is assigned Line 02, identifying the second design line used with matching supply units and interface cards.
The unit is classified as an HDS Drive Controller and is released as Version 1. A dedicated cooling fan runs continuously during operation, so the installation space should allow unobstructed airflow through the blower path and across the heat sink surfaces. Clean air circulation helps prevent debris buildup inside the cooling passages and supports consistent thermal performance during extended duty cycles. The controller relies on internal forced-air cooling and does not need additional external ductwork inside the cabinet. Cabinet ventilation should still provide a stable ambient environment so the blower can move air effectively through the module.
