Product Description:

The HDS03.2-W100N-HA42-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. As a programmable power module, it links servo and spindle drives to higher-level automation equipment, converting motion commands into regulated current for multiple axes inside DIAX04 racks. In industrial systems, it supports closed-loop motor control and works with a separate supply module so several axes can operate from the same platform. It can therefore serve as the current-control stage between the machine controller and the connected motor. This modular arrangement is useful in cabinets where motion, feedback, and power functions are divided across coordinated rack modules.

The controller receives commands through an analog interface, so velocity or torque references can be supplied as ±10 V signals that the internal processor converts into controlled output current. Because the command channel is voltage based, the unit can be paired with control hardware that outputs conventional analog references without needing a digital command card. Thermal management relies on a built-in air blower, which moves cabinet air through the heat sink so external ducting is not required under normal installation conditions. The power stage can provide a continuous output current of 100 A, giving the drive the capacity for demanding servo or spindle applications during sustained operation.

The controller depends on a separate supply module for DC link energy rather than generating that bus voltage internally. It is part of Line 03 and is Version 2, indicating a later revision within this product line. Standardized mounting rails, connector pinouts, and addressing conventions allow it to fit alongside related modules in the same rack system. The shared form factor also helps keep cable routing orderly in densely populated multi-axis cabinets. It also keeps the controller focused on power conversion and axis regulation.
