Product Description:

The HDS04.2-W200N-HA29-01-FW is a modular servo drive unit produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. It occupies one slot within a compact automation rack and serves as the regulated power stage that links a motion control CPU with servomotors. This arrangement lets the rack centralize power conversion while the higher-level controller handles motion commands for synchronized axes. By converting reference signals into precisely metered phase currents, the unit supports acceleration, velocity, and position control across multi-axis equipment. Typical use includes packaging lines, web presses, and gantry robots where coordinated motion is required under changing load conditions and repeated duty cycles.

The controller receives setpoint data through an analog command interface, so the upstream PLC or CNC sends continuous voltage or current references rather than discrete communication packets. Continuous analog signaling allows the command value to vary smoothly during speed changes and positioning moves. Power semiconductors and bus capacitors are sized for a sustained output of 200 A, enabling direct coupling to high-torque motors without external boosters. Thermal energy is removed by a built-in air blower that moves cabinet air across the heat sink and helps keep semiconductor temperatures within operating limits. As part of the DIAX04 family, the unit shares encoder wiring, diagnostic behavior, and auxiliary supply distribution used across the platform. The type code digit 04 identifies the power section line size for this controller.

The drive is Version 2, and this revision adds expanded gate-driver protection together with larger non-volatile memory blocks. The added memory capacity supports retention of operating data used by the controller. Its connector pinouts remain unchanged, so established cable assignments and cabinet layouts can stay consistent. The product is identified as an HDS Drive Controller, which keeps its device class clear in system documentation and selection records.
