Product Description:

The HDS03.2-W100N-HT70-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat. It provides axis power and motion control for DIAX modular drive systems, permitting a servo motor to run under closed-loop regulation in automated machinery such as packaging stations and material-handling gantries. In operation, the controller converts bus power into regulated motor current so commanded torque and speed can be maintained as the mechanical load changes. This supports precise positioning and stable motion on axes that start, stop, and reverse repeatedly during production.

This controller exchanges cyclic setpoint and feedback data over the SERCOS fiber-optic interface, allowing synchronized communication with higher-level motion control on a deterministic bus. It belongs to the DIAX04 controller family, so it follows the platform used in modular drive systems with coordinated axis control. Thermal management is handled by a built-in air blower, which moves cabinet air across the heat sink to manage semiconductor temperature during sustained operation. The power section is rated for 100 A of continuous output current, which is the maximum continuous RMS phase current available to the connected servo motor. Because command and feedback exchange occur in cyclic form, the controller can remain aligned with central motion commands during synchronized machine cycles.

The unit is part of Line 03, which identifies its design line within the platform for mid-range axis applications. It is released as Version 2 and is classified as an HDS Drive Controller. The controller is part of the HDS Drive Controllers series, so it uses the same general mounting pitch, wiring scheme, and diagnostic structure as related modules in a multi-axis rack. The revision code distinguishes this unit from earlier hardware releases in the same product family without changing its role as the drive’s regulated power and motion-control stage.
