HDS03.2-W075N-HT13-01-FW
The HDS03.2-W075N-HT13-01-FW is a drive controller produced by Bosch Rexroth Indramat and supplied within the HDS Drive Controllers series. Inside an automation cell, it receives low-level motion commands, converts them into regulated three-phase output, and supervises feedback from connected servo motors. That arrangement lets the controller manage current and velocity response close to the power stage instead of leaving those tasks to a higher-level PLC. In machines with several axes, this local control helps maintain smooth interpolation, repeatable acceleration, and stable motion when loads change quickly. It is suited to coordinated handling, packaging, and transfer systems where multiple motion channels must respond together.
Communication with host PLCs is carried over the SERCOS fiber-optic ring, so real-time setpoints and status data are exchanged with deterministic timing. The power section is rated for 75 A, allowing the unit to energize high-torque servo axes from a shared DC bus. A built-in air blower directs cabinet air across the heat sinks, and the unit is part of the DIAX04 family. This cooling arrangement helps maintain stable operating temperature during continuous duty without external ducting. The fiber-optic control link and onboard power stage let the controller react quickly to changing demand while remaining integrated with the surrounding drive platform.
The unit is part of Line 03 and is Version 2. It uses a deterministic command interface, so velocity loops inside the controller can stay synchronized with the machine clock without external timing hardware. The terminal layout for this line supports consistent wiring with related modules, which helps preserve cabinet organization in multi-axis systems. It can be installed in drive assemblies that depend on synchronized setpoint distribution and stable timing between axes. Coordinated starts, stops, and speed changes across linked motion sections can be handled through that timing behavior.
