HDS02.1-W040N-HT01-01-FW
The HDS02.1-W040N-HT01-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. It occupies the command layer of a modular drive stack, converting digital motion profiles into controlled current and voltage for multiple servo axes. Integrated control electronics execute position, velocity, and torque loops, while built-in diagnostics relay operating status to higher-level PLCs. By sitting between central motion processors and the power modules that energize motors, the unit provides coordinated control for automated machinery that depends on repeatable axis response. This arrangement lets the controller interpret incoming commands, supervise feedback behavior, and pass regulated demands to the connected power section.
The controller exchanges motion data over the SERCOS optical ring, so time-synchronized setpoints and feedback move through a deterministic communication cycle. Within the drive cabinet, it belongs to the DIAX04 family, which keeps mounting points and interface arrangements consistent with companion modules on the backplane. Current delivery to the attached power section is limited to 40 A, so connected conductors and related hardware must support that continuous load. Heat from internal signal components is removed by a built-in air blower, allowing operation without separate external cabinet cooling for the controller itself. The designation Line 02 identifies the second design line used for this unit. Because the communication link is optical, it is well suited to industrial environments where electrical noise can interfere with conventional signal wiring.
The unit is Version 1, which places it in the initial release for this order code. It is classified as an HDS Drive Controller, meaning it is intended for command and regulation functions rather than standalone power conversion. This separation keeps control processing distinct from the output stage that feeds the motor, so control tasks and power conversion remain in dedicated sections of the rack. In multi-axis systems, that layout supports consistent feedback handling and organized distribution of motion commands across connected drive modules. The result is a controller that fits structured drive assemblies where accurate axis coordination is required throughout normal machine operation.
