HDS04.2-W200N-HS57-01-FW
The HDS04.2-W200N-HS57-01-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. It serves as the axis power stage in automated drive racks by converting regulated DC bus energy into controlled three-phase output for servo motors. In assembly lines and machining centers, the unit links motion commands from a CNC or PLC to the motor so the axis can deliver controlled torque, speed, and position. Its closed-loop operation supports servo applications that require repeatable movement, synchronized axis behavior, and steady response under changing load. The controller is intended for multi-axis systems where one module is assigned to each driven axis.
Its command channel uses the SERCOS fiber-optic interface, which supports synchronous real-time data exchange between the control and the axis. This communication method helps multiple axes stay coordinated during interpolation and speed matching. A continuous output capability of 200 A allows the module to supply high motor current during sustained motion and heavy acceleration. Thermal regulation is handled by a built-in air blower that moves cabinet air across the heat sink to remove internal losses. Within the DIAX04 platform, the controller matches the mechanical arrangement used by companion axes in the same rack.
The unit is assigned to Line 04 and Version 2. Its mechanical format fixes the module height and depth for direct insertion beside other HDS units, which keeps adjacent drive positions aligned in the rack. The controller also includes regenerative braking and protective monitoring, so deceleration energy handling and internal status supervision are built into the device. These functions allow the module to manage braking events and monitor operating conditions such as overload or fault states during normal machine operation.
