Product Description:
The DDS2.1-F050-D is a drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. The unit serves as the power conversion and current regulation stage between a DC bus supply and servo motors equipped with digital feedback. By interpreting encoder position data and adjusting the output phases, it provides closed-loop velocity and torque control in automated machinery such as gantries, packaging lines, and printing stations. In operation, it receives motion commands from the control system and converts them into regulated motor current for coordinated axis movement. It is installed in multi-axis cabinets where synchronized motion and compact mounting width are required.
Electrically, the drive connects to a regulated DC intermediate circuit at 300 V, and its power section can deliver a continuous motor current of 50 A without derating. Control electronics are supplied from an auxiliary 24 V rail that draws only 500 mA, which helps keep cabinet power demand low. Internal losses released to the panel air volume reach 54 W, while an additional 215 W is removed by the integrated liquid cooling plate. This split heat removal reduces the thermal load inside the enclosure and supports stable operation during sustained duty. The sealed cooling circuit helps maintain semiconductor temperatures during repeated acceleration cycles and keeps the frame temperature steady under full torque operation.
The housing has an IP20 protection category, so the drive must be mounted inside an enclosed cabinet. Reliable operation is maintained across an ambient range of 0 – 45 °C and at altitudes up to 1000 m without output reduction. Cabinet ventilation should keep the surrounding air within that temperature range during continuous operation. The drive can operate in humid conditions, provided relative humidity stays below 95 % and absolute moisture does not exceed 25 g/m³. Storage is permitted from −30 °C to 85 °C when the unit is not powered. Its digital servo feedback interface supports rapid position loops after power-up.
