Product Description:

The DDS02.1-A150-D/S002 drive controller is produced by Bosch Rexroth Indramat as part of the DDS Drive Controllers series. It is a digital AC servo drive controller intended to regulate torque and velocity in automation axes that use synchronous or induction servo motors. Within a motion system, it converts commanded setpoints into controlled three-phase output so the connected motor can follow programmed profiles while the drive continuously checks feedback for accurate response. This arrangement makes the unit suitable for coordinated axis control in industrial machinery where stable speed regulation and repeatable motion are required.

The power stage can deliver a continuous output of 150 A, which suits medium-to-high inertia servo axes that need sustained current during demanding movement. Heat from the switching devices is removed through external air cooling, a method that draws ambient air from outside the cabinet and helps prevent warm air from circulating back through the drive. The housing has a protection rating of IP20, so the controller must be installed inside an enclosure to guard against accidental contact with energized parts. Position verification is handled through digital servo feedback, allowing the controller to close the loop directly and correct motion errors during operation. The unit is intended for ambient temperatures from 0–45 °C, where current delivery and monitoring functions remain within normal operating limits.

For installation planning, the controller can be used at elevations up to 1000 m above sea level without derating. When powered down, it tolerates storage temperatures from −30–85 °C, which helps protect the electronics during transport and warehouse storage. The unit belongs to Line 02 and is built as version 1. These identifiers indicate the product generation used for this controller type and help distinguish it from other versions in the same series.
