Product Description:

The HDS02.2-W040N-HS79-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. It serves as the axis control stage in industrial automation racks, converting digital motion commands into regulated motor power for conveyors, pick-and-place systems, and machining centers. Its role is to bridge high-level motion control and the motor power stage so commanded movement can be executed with controlled torque and speed. This makes it suitable for coordinated multi-axis systems that rely on predictable response from each controlled axis.

The command channel uses the SERCOS optical interface for time-deterministic data exchange between the drive and the higher-level controller. Within the DIAX04 family, the unit is part of line 02 and version 2. The controller has a rated current of 40 A for continuous output, which suits medium-power servo applications that require steady current delivery over long duty cycles. Heat is removed by a built-in air blower that pulls cabinet air through the heat sink to control internal temperature. The enclosure has a protection class of IP10 per DIN 40 050, and the windings use insulation category C per DIN VDE 0110.

Installation height and temperature limits should be observed during system layout. The controller can be installed at elevations up to 1000 m above sea level without loss of performance. During operation, the ambient air must remain within +5 … +45 °C, while storage or transport may occur between -30 … +85 °C when the unit is not energized. Operation above the standard altitude or temperature range requires derating so the power section and cooling path are not overloaded. If the ambient temperature rises above the nominal operating range, continuous current must be reduced, and the temperature must never exceed +55 °C during derated operation.
