Product Description:

The DDS02.1-F150-DA02-00 is a digital AC servo drive controller built by Bosch Rexroth Indramat and supplied within the DDS Drive Controllers series. It forms the power and regulation section between an Indramat supply unit and a synchronous or induction servo motor, providing vector-controlled torque and speed commands for automated machine axes in packaging, printing, and material-handling lines. The unit is intended for closed-loop servo operation, where motion commands from the machine control are converted into regulated motor current for accurate axis response during acceleration, constant-speed travel, and stopping.

This controller communicates with higher-level PLCs through an analog interface, allowing ±10 V speed or torque references to be processed directly by its internal processor. A continuous output capability of 150 A supports large-frame motors without external amplification, which helps the drive handle demanding axis loads in larger servo systems. Rotor position and velocity are returned over digital servo feedback, so the unit can carry out commutation and closed-loop control at high update rates. The drive is part of Line 02 and is identified as Version 1, matching the DA02 analog control arrangement used for this model.

Thermal management is handled by a coolant circuit that routes conditioned liquid through an integral cold plate, removing switching losses more efficiently than air channels. Because the heat sink is optimized for coolant-based cooling, the drive can be installed in sealed cabinets where dust or other airborne contaminants must be kept away from the electronics. This liquid-cooling approach also reduces the amount of heat released into the enclosure, which helps stabilize internal cabinet temperature during continuous operation. The regulated power stage and feedback processing allow the unit to support precise motor control on axes that require steady torque delivery and repeatable speed regulation.
