HDS02.1-W040N-HS78-00-FW
The HDS02.1-W040N-HS78-00-FW drive controller is produced by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. It is designed to regulate servo and spindle axes when used with matching power sections, supplying command execution and protective functions to the connected motors. In industrial automation systems, the unit closes motion loops and monitors feedback so multi-axis machines can maintain commanded velocity, position, and torque during operation. Its control section processes motion data and feedback changes quickly enough to support regulated axis movement under changing load conditions. This makes the controller suitable for equipment that depends on synchronized axis behavior across several coordinated drives.
Communication with higher-level control is handled through the SERCOS optical interface, allowing deterministic fiber-optic data exchange with the control system. The power stage supports a continuous output of 40 A, which is the maximum motor phase current the controller can deliver without derating. Thermal control is handled by a built-in air blower that pulls cabinet air through the heat sink to keep semiconductor temperature within limits. The unit is part of the DIAX04 platform, so it follows the mechanical and electrical layout used by that system. It is assigned to Line 02 for this performance class and medium-power axis range.
The unit is classified as an HDS Drive Controller, which distinguishes it from supply and feedback modules in the same rack system. It is identified as Version 1, so the parameter set and diagnostic support should match that release. The designation 00-FW indicates the firmware slot used for the application software. It is used in modular racks where separate supply and power sections are installed beside the controller. The controller is intended for coordinated multi-axis drive systems where stable command processing and continuous feedback evaluation are required for controlled motion.
