HDS02.1-W040N-HA14-01-FW
The HDS02.1-W040N-HA14-01-FW is a modular drive controller produced by Bosch Rexroth Indramat within the HDS Drive Controllers series. It serves as the power and regulation stage for Indramat servo and main-spindle modules and fits into the same backplane racks as associated power supplies. Because it operates between the supply section and the motor, it processes incoming commands and regulates output current for closed-loop axis operation. In industrial automation systems, this allows the connected motor to follow programmed speed or torque profiles with stable response during changing load conditions.
The drive uses an ANALOG command channel, allowing it to accept ±10 V velocity, torque, or position references from a higher-level CNC or PLC without added digital fieldbus hardware. This interface suits control systems that already generate conventional analog reference signals and need direct command transfer to the drive. Thermal management is handled by an internal air blower, so cooling air must be routed through the module instead of relying on external heat sinks. Under continuous load, the power stage delivers a rated output of 40 A, which supports medium-frame motors during acceleration as well as steady operation.
As part of the DIAX04 platform, the unit uses the rack-based format common to coordinated multi-axis drive assemblies. The controller is assigned to Line 02 and built as Version 1, which place it within this product generation. It is an HDS Drive Controller intended for use with compatible supply modules and axis components, allowing direct installation in the matching system architecture without special adapters. Its rack-mounted layout keeps the controller aligned with neighboring modules in a shared cabinet and supports orderly cable routing across the drive assembly. This arrangement is well suited to machines that use centralized power distribution and coordinated axis control.
