Product Description:

The HDS04.2-W200N-HT27-02-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. It mounts inside DIAX multi-axis racks and serves as the regulated power stage between the system power bus and a connected motor. By converting digital motion commands into controlled motor current, the unit supports precise positioning and stable speed regulation in automated machinery. It is used in systems where multiple axes share a rack-based drive platform. This arrangement allows the axis to respond quickly to command changes while maintaining closed-loop control during continuous industrial operation.

This controller exchanges setpoints and feedback through the SERCOS fiber-optic interface and belongs to the DIAX04 family. SERCOS communication allows cyclic command exchange between the motion control and the drive. Thermal management is handled by a built-in air blower; the fan moves cabinet air across the heat sink so no external ducting is required. The power stage is rated for 200 A of continuous output, which supports high-demand servo axes. Housing protection is limited to IP 10 per DIN 40 050, so the unit is intended for installation in a closed cabinet. The controller operates within an ambient range of +5 to +45 °C. The unit is Version 2.

At elevations up to 1000 m above sea level, the controller can deliver full current, while higher installation sites require derating because thinner air reduces cooling effectiveness. Windings and internal power components use C insulation class according to DIN VDE 0110, which supports the thermal stress that can occur during dynamic duty cycles. When surrounding air climbs toward the derated ceiling of +55 °C, the unit reduces current to protect semiconductors. During storage or transport, it tolerates temperatures from -30 to +85 °C, and these limits apply when the controller is not operating.
