HDS04.1-W200N-HA19-01-FW
The HDS04.1-W200N-HA19-01-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. It converts motion commands into regulated three-phase output for servo axes, so it forms the core of machining centers, gantry stages, and transfer lines where precise current control is required. In typical installations, it sits between the mains supply and the motor, handling acceleration, deceleration, and fault monitoring for each axis. This arrangement lets the controller regulate motor response closely during changing loads and direction reversals.
Control data reaches the drive through an analog interface, so command voltages from the CNC or PLC are translated directly into torque-producing current. Motion algorithms run on the DIAX04 processor platform, which keeps operating behavior consistent across the product line and simplifies parameter transfer. Cooling is handled by a built-in air blower that moves cabinet air across heat sinks and avoids external chillers. During steady motion, the power stage can supply 200 A, which is the ceiling for motor armature current before thermal limits are met. The unit also includes front-panel diagnostic ports, along with current, velocity, and position loops for closed-loop control. These functions help the drive maintain stable axis response during rapid interpolation moves.
This module is part of Line 04, which sets its mechanical width and backplane contacts inside DIAX multi-axis racks. The unit is Version 1. Because it occupies a high-current slot and uses forced-air cooling, filters should be kept clean and airflow clearance should be maintained so the blower can deliver rated performance. Clear space above and below the unit helps cabinet air move freely through the cooling path and keeps internal temperatures more stable under sustained load. Clean airflow paths also help limit dust buildup on heat sinks and circuit boards during continuous operation in enclosed cabinets.
