Product Description:
The HDS02.2-W040N-HS78-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. Installed in a multi-axis rack, it converts DC-bus energy into regulated three-phase output for precise speed and torque control in machinery such as machining centers, printing lines, and material-handling cells. It links directly with higher-level motion processors to support dynamic positioning tasks within automated production sequences. By regulating motor current inside the rack, it helps servo and spindle axes respond predictably during acceleration, deceleration, and holding phases. It is suited for systems where several axes share a common power structure and must follow synchronized commands from a CNC or PLC.
Command signals arrive through the SERCOS optical ring, allowing real-time exchange of setpoints, diagnostics, and parameters. The optical interface supports coordinated data transfer without separate analog command wiring between the control system and the drive rack. The power stage delivers up to 40 A of continuous output current, which suits medium-frame servo or spindle motors in combined axis groups. Thermal energy is extracted by a built-in air blower, eliminating the need for external ductwork between neighboring modules. The housing has an IP10 rating, so it must be mounted inside a closed cabinet to guard against accidental contact. Internal wiring uses insulation class C, and reliable operation is permitted from +5 to +45 °C.
Installation altitude is limited to 1000 m; sites above this height require output reduction because thinner air lowers cooling effectiveness. At ambient temperatures up to +55 °C, controlled derating is required instead of full-load operation. For storage, the electronics can withstand temperatures from -30 to +85 °C. As part of the DIAX04 drive family, the unit is in line 02 and version 2. These operating conditions are relevant wherever cabinet ventilation is restricted or the machine is installed above standard plant elevation.
