Product Description:

The HDS03.2-W075N-HA17-01-FW drive controller is manufactured by Bosch Rexroth Indramat and forms part of the HDS Drive Controllers series. Mounted in a DIAX04 automation rack, the unit converts the shared DC bus into regulated phase currents for servo modules and reports diagnostic data to the PLC for coordinated machine control. By handling energy distribution and protection tasks, it supports multi-axis machining centers and synchronized pick-and-place cells that require several axes to run together. Its modular card format suits organized rack installation in continuous-duty plants where several drive cards are installed side by side.

Control commands enter the front panel through an analog interface, so velocity and torque references are carried as ±10 V signals that the drive translates into pulse-width-modulated current for the connected motor axis. The controller belongs to the DIAX04 family, which means it shares bus rail dimensions with companion supplies and feedback modules used in the same rack. Thermal management is provided by a built-in air blower, eliminating the need for external ducting and helping the power electronics stay within their operating temperature range during continuous operation. An output capability of 75 A indicates how much motor phase current can be sourced before electronic current limiting intervenes. The unit is part of Line 03 in the HDS range, matching it to medium-power servo axes.

The drive is Version 2, with expanded parameter memory and additional fault codes for more detailed diagnostics during operation and fault handling. In a multi-axis stack, the unit functions as an independent axis card that can be added alongside matching modules with the same cooling profile. This arrangement lets the rack support multiple servo channels while keeping the front-panel layout and control method uniform from one axis position to the next across the system.
