Product Description:

The HDS03.1-W100N-HS12-01-FW is a modular drive controller produced by Bosch Rexroth Indramat in the HDS Drive Controllers series. Installed in DIAX04 motion control cabinets, the unit serves as the interface between incoming DC bus power and the servo axes it regulates. It conditions power from the common bus and meters it to the connected motor according to commanded motion values. Within automated production cells, it translates digital motion profiles into controlled current pulses so connected motor modules can follow precise speed, torque, and position trajectories.

The controller communicates with the master PLC over the SERCOS fiber-optic ring, so parameter data and real-time setpoints are exchanged deterministically during operation. It belongs to the DIAX04 family, so it fits the mounting and module arrangement used by related units in the same rack. This makes it suitable for rack-based systems where several axes are controlled from a common platform. Continuous output capability is rated at 100 A, which is the maximum motor phase current the power section can deliver without exceeding thermal limits. Thermal management is handled by a built-in air blower that directs cabinet air across the heat sink fins instead of requiring external ducting. The product is part of Line 03, which identifies its design line within the series.

As an HDS Drive Controller, the unit is intended for multi-axis positioning tasks coordinated by Rexroth motion control. The product is Version 1, which identifies the hardware revision of this unit. Its enclosure, I/O connectors, and diagnostic LEDs follow the module format used across this platform, which helps keep cabinet layouts consistent. The front layout also keeps status indication and connections easy to follow during normal operation. That common module format supports orderly installation in drive racks and keeps the front-panel arrangement consistent across matched assemblies.
